Stealth Games do need an audbile way to tell the player "I am done searching and will now go back to a lesser state"

[@BonaparteBardithion]

@Yo Momma It is important that they have a bark at both ends of the alert period. The same thing can be accomplished through the use of body language, but both barks are useful in limited visibility. You can also use it to indicate if other guards are alert now. Instead of "Must've been the wind" they might sometimes say "Better call it in" and all guards are set to alert for a set period of time. Different closing barks can be used to warn the player if there are varying reactions.

I once tried to prototype an "inverse stealth" game, where you had an army of guards and were looking for a spy. The guards were easy enough to create, but the prototype fell through when I realized how many things the spy's AI had to keep track of. Known hiding places, not taking paths currently in a guard's vision cone, if they're spotted they'd have to path an escape route that doesn't take them past a half-dozen more guards... it was too much.

[@zedudedaniel]

You could make it an asymmetrical game, where one player is the spy vs the mastermind player who hires guards to defend things

[@allooutrick8266]

What if you approached it with the ideas of a puzzle game? It might help to do things like give guards and other things a radius the spy should avoid. If you can manage it, you could give the spy a "priority level" kind of thing and use that to influence difficulty. As for hiding places yeah that can get complicated as you may have to declare things specifically as hiding spots and use what's discussed in this video to determine if and when they're caught.

[@allooutrick8266]

By priority levels I mean like how soon after entering this radius should they attempt to escape it. Side note, it almost feels like the way games highlight trails you should take to your objective isn't all too different from this.

[@expert862]

you can just make it a multiplayer.

[@KyleJMitchell]

Yeah, that's not far from trying to write an AI that can play a given stealth game the way a human player might. There's a reason AI like that is such active research; it's *hard*. You might get farther by giving the spy its own behind-the-scenes cheats (like teleporting him to a good-enough path or being invisible to the guard that last spotted him for a bit) to short-circuit some of that complexity.

The batman games are amazing at this, as the guards react to your actions throughout the stealth sections. One of their guys goes down, they all start looking for you, only a few left, they start going back-to-back so you can't sneak up on them. Only one left, he starts freaking out at every little sound. You can throw a batarang at a nearby wall and he'll shoot in that direction in blind panic. He will also look everywhere and turn often, which makes sneaking up on him more challenging.

I'd love to see a discussion on rewards in stealth games: I feel like it's the only genre out there that really *demands* perfection from the player, there's always some kind of "ghost bonus" for never getting seen... leading to stealth games being in the pantheon of save-scummiest games out there, next to classic isometric RPGs or Xcom. I'd rather see a "one run" bonus, where you make it from the start of the stage to the end of it without dying or restarting at a checkpoint: encouraging players to play through their mistakes and see the run through regardless of what happens.

[@Laezar1]

That's actually a brilliant idea. I always end up save scumming cause I don't really have the willpower not to and have no incentive to not do it. I usually find an excuse like "this was clearly bullshit detection" the first time I do it and then it becomes easier and easier to savescum. Having something to push me to actually do my best in all situations and accept my mistakes would help. Sidenote but I'd like something similar with games like xcom and fire emblem.

[@ineffabletryx6528]

The only thing is that games like Shadow Tactics: Blades of the Shogun actually encourage save scumming by warning you if you haven't save within a minute, because it realizes how easy it is to make a plan, think it will follow through, and then underestimate your character's speed, or something happens that you just didn't expect entirely. Sure, some stealth games that make it easier to get back into cover, and games like Hitman 2 actually kind of do reward this because it's a lot easier to predict what will happen, and in master mode you can only save once. It really just matters about what game you're playing, and whether save scumming should be encouraged or discouraged.

I can tell I'm going to enjoy this mini-series immensely.

[@thegameneededme5]

Man, I love the art style and animations in Mark of the Ninja so much. Also, I really like the system in Alien Isolation where using the motion tracker creates sound which can alert the Xenomorph, so you’re encouraged to use it sparingly. Tying something that really benefits the player to a stealth system that could get them killed if they over-rely on it creates an interesting balance.

[@ЯношБан]

I found that this kind of approach to the design of the motion tracker is actually applied to pretty much every item/mechanic in Isolation: the more you use the flamethrower on the Alien the more resistant to it it will become and more persistant/aggressive it will get; use certain distraction too much and the Alien may get more and more bored with it up to completely ignoring it next time; as helpful as the items and tools in your inventory are, they pose a huge (but varying) danger/problems to their user, and the game does its best to point that out - all done to create and add to tension, stress and anxiety. And I found it working out for the game really, really well. Its really interesting in general, how going against some of the player/user friendlier things mentioned in the video (like guards having their hearing cut in half when they are off-screen, or awareness meter displayed to the player) does not necessarily mean bad design, as it depends on the type of stealth game being made, its core focus and core experience that it is supposed to provide. Having said that, maybe not related, but Isolation really would've benefitted from a more in-depth, reactive and just plain better AI for humans. They worked fine, and on points great, but they can be comical, and unlike the Joes, not in a good way.

[@stevethepocket]

I'm still waiting for a stealth game where your flashlight is the kind you have to loudly wind up to recharge. It's been staring game designers in the face ever since those hit the market.

[@Alex36973]

That's why I love that game

[@ЯношБан]

Pocket Fluff Productions while an interesting idea, it seems more like a little annoyance to keep track of, isn't it? Tho, I guess depends on the game. If it's a stealth-horror/stealth survival-horror, where it most likely would be designed in a way that will get you killed, that'd be not ideal, but in other stealth games, with more forgiving enemies when it comes to spotting and becoming aware of you, that could work nicely.

[@TheIllio]

I would love to see a stealth game where guards get higher awareness whenever they almost spot the player. Like when that guard saw something suspicious, it would take a better look at the surrounding and would react faster if something occured again. However, in most games, guards merely take a quick look at the place where they spoted something and return to idling around like nothing happened. So some kind of rising alert level for guards would be cool. From reducing the time they need to spot the player to actually leaving their idle status permanently and actively searching for something until they find some explanation (like a cat or something, which could actually be used as an distraction to lower the alert level).

[@levelzero8445]

Most stealth games right now have such a system, although rudimentary. When the player is spotted and hides again or a body is found, the guards will stay more alert and aggressive even after they return to their routine. It's often limited by the fact that those guards can't alert others to your presence, so you get a vigilant guard while the others stay the same.

I'm glad you mentioned the _Sly Cooper_ series, because that's exactly what I was thinking of when you mentioned representing sight cones in 3D. It's a system that fits the game very well, too. The fantasy offered by playing as Sly Cooper isn't being constantly on the edge of your seat, evaluating and guessing whether you can be seen; it's about being a master thief who's so experienced that those things come as second nature.

[@Pooofcomify]

Despite all these mechanics, I've always wanted to play a stealth game where the guards are as human as possible. For example, we are aware of someone pretty instantaneously; it's not like we need time to be aware of a person after we've seen them. Another thing some games do is returning the guard to a calm state after they've been slightly alerted. A real life person would stay on edge for the rest of the encounter. I think a stealth game like this would be unreasonably hard, but I've always wanted to try

[@JS-ue2si]

The problem with a lot of military stealth games, and even FPS games, is that during the mission, the player is responding to their environment and situation for the very first time. But in most military ops, by the time soldiers put their boots on the ground, they've memorized the layout of each building, know exactly how many people are expected to be there and where they'll be, memorized the routines of the guards and staff, know everything about any security systems, and have even practiced a dry run several times on a mock set that looks like the op. So I'd LOVE to see a hyper-realistic stealth game where gunfire alerts just about every guard in the area and where the guards can see exactly what you see (Like, it doesn't make sense that I can see Sam Fisher hiding in the dark but they can't). And have it be so realistic that pretty much the only way to pass the mission is to plan it well. So the game becomes about forming the best plan and then executing it well.

[@voidvma]

Try *Payday 2*, altough it's full of DLCs, the base game and free DLCs lets you pre-plan each heist: see map, place some useful things (body bags, medkits) and you can even draw on the map for other players to see. I recommend playing it with at least one friend.

[@BygoneT]

Classic Hitman games dude. Though they're silly in essence, they work precisely like a trained assassin receiving info on a job. Especially in blood money, you can request information about the target's habits, the establishment's weaknesses, you can examine the skeleton of the level before going in, and so on. Splinter Cell is a bit different, yeah. But I never had any trouble with it. My extreme caution as a child made me stalk the shadows and abuse sticky cams so much that I was basically never caught. Except in Kalinatek, because fuck the first big hallway where they turn on the lights. I remember getting a heart attack *very* clearly there. I ran into a mine face first thinking they were gonna get me.

Bruh, you highly overestimate the military. That sort of intelligence is rare. The military doesn't go in raw, it generally has a baseline, but not the full blown schematic. And unless its a super important op, you won't typically do dry-runs - as constructing the dry-run costs a good chunk of money. You may go over it in a terrain model, or maybe run a few TDG's (tactical decision games), but a full on dry run is rare.

I liked how *Mark of the Ninja* had the condition of scared shitless, in addition to idle, suspicious and in pursuit. I'd love more 3D stealth games explore guards with different personalities and fear/anxiety levels, when if you're good enough they might say "Fork it, I'm not paid enough for this." Maybe some cool traits from psychological to supernatural to throw you out of the loop sometimes. Imagine hiding from a vampire, that can't see you, only hear and is forced to avoid holy places, running water and can be distracted by having forced to count scattered seeds. Or a suspicious guard not calming down, once they've seen som treasures missing, or a supersticious guard thinking the place is haunted after you prank them, or magical gumshoe being able to follow your steps, but only in the same exact order (so you can always make path longer), or the guard that is watching cameras in real time, so you have a chance be not seen by them, at the cost of having harder time later, etc.

[@GameDevYal]

Considering how many games slap on stealth mechanics to spice the game up, mess up all the mechanics, and instead just ruins the experience for one level, making this miniseries is a genius idea :D (Speaking of, having illustrative examples of games that do the exact opposite of a stealth "best practice" to highlight just why the mechanics work when used properly could be a nice educational touch - my main pet peeve is when a game doesn't give you any feedback on whether you're hidden or not, so you need to trial-and-error through an invisible hedge maze to find the path the designers want you to take)

Hello! Your videos are incredible. I think an interesting video could be how games balance, not just through mechanical skill, memory, and strategy. But around Fear. Take for example the mechanics of Alien isolation, which is a fairly straightforward stealth puzzle game, which then becomes incredibly difficult because you can't keep a clear head. As said by Ras al Ghul in Batman Begins. "Feel terror cloud your senses" Another example of this could be the stress induced difficulty of the lockpicking at the end of the water monster corridor in Amnesia: The dark descent. Or anything you do while getting chased by the regenerator in dead space.

Shadow Tactics is the best stealth game I have ever played so I'm glad you included it. Minmi Games did an absolutely phenomenal job in not only modernizing the "commandos" formula, but also improving upon it.

[@mayatunes]

I'd love to see a mini-part about how stealth interacts with combat, and how the different ways and numbers of how to deal with enemies changes the feel. Like, how do games like MGS (which have multiple different ways to dispatch enemies), compare to games with only one/one main method of attack (Mark of the Ninja), or none at all (survival horror)? Or how most games let you kill guards, but others don't?

[@ЯношБан]

Hmmm, "none at all" doesn't necessarily mean "survival horror" tho. Actually, survival horror games usually allow you to kill/dispatch your enemies and engage in combat (Look Resident Evil games apart from 4-5-6, those are action-horror; *System Shock 2, Alien:Isolation etc), however, even in a shooting-focused survival horror, it is always quite risky to do so, and is not always a viable solution. In traditional survival horror games ammo is always limited, you are vulnerable and the threats are tough or deal alot of damage, if not both, but you're usually not forced to fight, as you may be able to run away, making engaging in combat a tactical decision. In a game like Alien: Isolation engaging in combat can be lethal and quite often, even with a group of survivors, but you can use that to your advantage and in general you have a number of different ways to kill/dispatch low tier threats, and survive an encounter/fend off the MVP that is the Alien. Horror games that have no means or ways to engage or kill the threats are games like Amnesia, Layers of Fear, Outlast etc and I imagine you were referring to exactly those games, specifically Amnesia and Outlast, as they are stealth focused. Many horror game enthusiasts don't consider those as survival horror, rather as a beast of a somewhat different breed, that still has no proper definition/name, I definitely couldn't find it. Some people call those simply "horror games" buuut that's just bad as it is already taken and stands for, well, horror games but of every kind/sub-genre etc (action-horror, survival-horror and so on). Some say they should be called as "stealth-horror", which is better, probably best option, but still I think there are some problems with it. I even read some people refering to those games as "modern horror" which is probably even worse than just calling them horror games, so yeah.

[@mayatunes]

@@ЯношБан Fair enough. I just like the idea of a stealth game where you can't just "remove" the guards. I know that you don't have to allow killing in order to "remove" guards, you can incapacitate them in other ways, but still.

[@ЯношБан]

@@mayatunes I get it, I also like that idea, I mean, the more diverse the genre the better in general. I just wanted to point out that if people talk "survival horror" and mean by that games like Amnesia, Outlast, Layers of Fear, or, on the opposite end of the spectrum, Dead Space, RE5 and etc, that may not be really correct.

[@BadNessie]

My favorite fun stealth section is that of UnMetal, where you even get to choose the type of guards (not knowing what it will mean exactly) by telling your story in an interrogation and then playing it out in hindsight. This game deserves a huge mention!

This reminds me of an amusing post I saw on Facebook months ago. One person is talking about how there are two ways to play stealth: no-one sees you, or leave no-one alive to see you. The second person remarks: so stealth, and Russian stealth.

[@RobinOttens]

The Siren games have an interesting solution for view cones as well. Letting you literally switch your view to see what the enemies are seeing from their perspective, as if switching channels on a tv. As a horror stealth game, this has the added benefit of giving you that classic view from the monster's eye that is used in so many horror movies. It's also a good way to scout around without having to risk getting spotted. And when you do decide to get a move on, you lose the enemy perspective, have no radar screen for overview, and will have to trust that the enemy is still where you last saw them. Adding a feeling of tension that perfectly elevates stealth game tropes into a full on horror experience. Siren on the PS3 somewhat alleviated this by letting you split the screen, so one half is your own view, the other half shows what your 'sight jacked' enemy is seeing, but only for one enemy at a time.

[@PlebNC]

My favourite thing in stealth games is all the actions that a player can take that aren't the direct route or simply shooting enemies and play up the particular stealth fantasy the game's portraying. For example in the Batman Arkham games you can get a gadget that remotely disables enemy guns. Depending on the game, this gadget either has a long cooldown between uses or a fixed number of uses per encounter. Nothing is quite as satisfying as getting the guards super-scared of Batman, disabling the remaining guns and then intentionally revealing myself and watching the horror on the guards faces as they realise their guns, their only strength against the Batman, is worthless and then I take them out. I don't even run after them, I walk because Batman's that badass and the enemy's that screwed. While strong, this strategy has some downsides - The long cooldown/limited uses and guards who realise their guns don't work with either switch to melee combat or run off to get a new gun from a supply crate. This means the player has to plan their attack and move swiftly like the Batman would to make the most of the temporary advantage.

[@Shoxic666]

the two styles of stealth: hiding from monsters & hunting down prey

[@adams13245]

I wonder if you could make a hybrid of these types. One where you start out hiding from the monsters in the shadow, then, as you progress, become the monster in the shadows. I guess Arkane's Prey gets to this somewhat; the player starts out afriad of every small object, but, as the game progresses, you gain the same powers as the Typhon enemy and can pull the same stuff off.

[@ludensarahan]

Metal Gear Solid 5 is the hybrid of those. I highly recommend it.

[@thisylvain]

Good thing about the confinement is that we get even more good content on KZbin! Thank you!

[@mateuszgwizdalla]

Interesting how the camera really empowers the player characters, and how few stealth games opt for first-person (Thief stands out to me). It's kinda ridiculous you can see both your player crouch behind cover, and exactly totally everything behind that cover, yet often in the player characters shoes all that information wouldn't come from their actual perception. It's a sort of player-omniscience (perhaps that would be an interesting topic to cover?)

[@mrredcheeks4018]

Zelda: Breath of the Wild did a good job with their fuzzy detection. Different enemies have different levels of awareness based on their danger level which is the best way to fight them. Some Lynel can see from really far away but the best way to fight them is through mounting and attacking them since it's a 1 v 1 encounter, but are otherwise avoidable. And on the other end less aware bokoblins and such you can sneak attack to kill, but will call for reinforcements if they spot you since you typically fight them in encampments.

[@MidnighterClub]

I think Zelda: Phantom Hourglass deserves a mention! (Fully visible cones, near instant discovery, safe zones, best Link.)

[@Roxor128]

I can think of a situation where you might want to do extra raycasts in addition to parts of the player's body: Checking for light visibility. If you're just checking the player, then standing in a shadow with a lit area behind would show them as hidden when they really shouldn't be. Add a few extra points around the player's hitbox that rays would normally go through and continue them if they don't hit anything between the guard and target point and sample the light from where they eventually do hit and use the contrast between there and the player to influence the visibility calculations.

I love stealth games! I've played a lot, and my favorites are the ones that factor in believable tactics. Splintercell: Blacklist was the first stealth game that gave me bonus points for leaving enemies completely untouched, which I thought was very cool. Even one dead or unconscious body should be enough to put an entire compound on lock-down, but most game guards just chalk it all up to "imagination".

[@yashasvik2958]

The only thing in stealth games that doesnt make sense is how if one person sees you, everyone in the compound and their deceased grandma knows where you are and mission failed

Not in every stealth game, in MGS V the guards scream "Enemy/Intruder spotted" after he spotted you to alert the other guards. A bad example of this is Watch Dogs 2 though.

Talking about the alert state in guards, in Thief: The Dark Project, if the guards are idly walking, you can knock them out in one hit using your blackjack. However, if they are on alert (if they hear you, even if they haven't spotted your exact location,) you will be unable to knock them out. Sure, you could still try to kill them with your sword, but, if you play on harder difficulties, you will get an instant Game Over if you kill anyone. Awesome video!

@Richard Foran Would you really want to play a stealth game where, if you were spotted once, the guards entered an alert state that lasted for hours of time? That one dead body you didn't quite hide well enough would send the entire base into full alert for the rest of the session? You do know there's a difference between the fantasy of being a hidden ghost who no one knows is there and the reality? For one thing the latter requires a ton more push ups.
