Speedrunners BREAK Physics in the most Stylish way Possible

Speedrunners abuse the oversights in developer made physics, mainly inertia. In many speedrun world records you will see players bunnyhopping, yeethooking, and more to glitch and skip their way across the game at great speed. Today we are going to be breaking down how inertia can be manipulated to some awesome ends in many games but mainly Devil May Cry 4.

I think that if they make a DMC6 and Inertia is demand enough they could easily put it in because of how "easy" it was for modders to add it in DMC5.

[@MrSandmanTBB]

That's because it's already in the game, it's just that some stuff now halts momentum in the air

[@Kaliospectre]

@@MrSandmanTBB Vergil is a prime example since his trick still retains inertia in 5.

[@emaitchess3821]

They removed inertia but they made it so u can keep moving in your desired direction through the air with just the left stick. Yes people have spent a shitton of time practicing to master air movement in 4 but they made it so in 5 everyone can do it with a basic knowledge of the game, without having to do that. it's not a necessary mechanic they wouldn't need to add it. Just breaks their game more, maybe fun for stuff like these but in the end it's just that

[@Kaliospectre]

​@@emaitchess3821 I'm of the opinion that they could've done that while keeping inertia, because I don't really see the use in halting the inertia as it's a singleplayer game. It's not like other people are using inertia to fuck you up in PvP or something like that, plus the motivation to master inertia is intrinsic, it's just to look stylish. There's no advantage in terms of damage for using inertia. And the other uses of inertia still can't be done with the left stick like guard flying, skyrunning, or star rave's different variations, it only works for rainstorm.

[@alastor8091]

@@emaitchess3821 kind of made me a little salty because once 5 was released, I spent hours figuring out how to do all of the inertia stuff, sword raves, enemy stepping which I was never good at, switching to all styles in combat, mobile Rain Storms, I learned it all and became so much better I even beat Blood Palace when I couldn't get past floor 30 before. I won't say the time was wasted because I did become ridiculously good in 5, but a lot of techniques were just canned.

Before I get deeper in DMC and play the real one(not the reboot), I was thinking it's just a cool slasher game, like God of War But now, oh boy, not only the storytelling is amazing, not only the gameplay gives you a sense of real control of a death-machine, but also watching such amazing guys, like Donguri and DK, send shivers all over my body! I thought Tekken or MK combos are something astounding, but watching DMC "Bosses" is really make me feel so incompitent and motivated!

[@M7S4I5L8V2A]

One other thing DMC4 had unlike the others was Reversals which got cut from 5 despite being in the demo. I think at one point Itsuno did want that to be a thing though because he said he wanted Dragon's Dogma to be an action game without lock-on. Reversals would be something everyone could use with that.

[@Gamegalgegod]

Reversals aren't exclusive to 4, these can be done in 3 as well. In 5's case they are in the game and you can do them when no enemies are present but as soon as enemies are targetable the ability to do a reversal is removed aside from very specific cases like EX-Streak. Itsuno did confirm during a livestream post launch of the game that this was "removed" because they didn't want a player to accidentally do this after seeing it be done during play testing. Which doesn't quite make sense since it requires you to buffer buttons which can be pretty hard accidentally but hey ho, what's done is done now.

[@M7S4I5L8V2A]

@@Gamegalgegod Yeah I was there for the stream and saw it live. I was kind of worried but you have to understand they don't quite understand the terminology and the stream was for english fans. There were points where he had a hard time understanding but they had Mat there to translate. I remember him saying that if a thing is cool then they try to keep it in. The response you're talking about I remember being when repeatedly being asked and apart of Mat's damage control. He could pretty clearly tell that people didn't like the answer we got.

DMC4 to DMC5 is like Melee compared to Smash Ultimate.

Good analogy in my opinion. One has the more advanced tech and such, while the other one wins in just about every other way.

[@sierraamaya]

Thats the problem with funny glitchs sometimes you cannot move them to another place.

[@chrisrockett5897]

Yep. One is a bit broken, has crazier movement, disliked due to control layout, and has a bit of a smaller fanbase, while the other is a tad less broken, has a better layout, more beginner friendly gameplay, and is loved by most of the fanbase.

[@Rodro257]

Yeah, i dont think dmc5 is a bad game even for high level players, but dmc4 is better.

[@guilherme100099]

@@edgyboi1995 What other advanced techs are you talking about? Just asking just out of curiousity

[@TOMxLEON]

Great explanation for inertia in DMC4. Now I really understand why some people like DMC4 more than 5. But like only 0.0001% of players really know how to utilize it in such a stylish way. I think DMC5 removing inertia while adding a lot more stuff that more people would find easier to implement in their gameplay and be really stylish won't really take away the fun. (Personally DMC5 is my favorite action game by far)

[@WanderDMC]

This makes it sound like implementing inertia in DMC5 would be difficult or be some sort of compromise. To make it function like in 4 sure, but technically speaking it's already in 5. They just designed it so that you lose your inertia almost instantly. And whether or not inertia is in the game or not has nothing to do with having many moves. Adding inertia to the game isn't some sort of trade off or something. If anything it's more than likely possible that they put more work in to make sure that inertia wasn't present in the game

[@salvale9184]

@@WanderDMC What 5 gained from removing inertia is making moves feel much more intuitive and easy to understand than 4. Personally I never liked inertia but understand how technically yes, it did add more depth to some moves. The moves that do alter inertia however feel rather arbitrary, for example Nero's midair charge shot giving you backwards momentum doesn't exactly feel nice when you're trying to work it into a combo because it simply forces you to grab or air caliber back to the target, and neither of those moves feel well tuned to the slight-but-noticable bit of inertia the airshot gives you. As I said yes, this does add another dimension to combat but all this comes down to is another unintuitive extraneous factor to manage, and in a game where you already have to manage the positions and velocities and stun values of you and your enemies, it just strikes me as an annoying distraction more than anything. If you find it fun, that's fine but I just do not and neither of us is necessarily right in that

[@WanderDMC]

@@salvale9184 Not really sure what this has to do with my initial comment tbh. Aerial charge shot moves you backwards regardless of whether you choose to carry the inertia or not. Pretty sure it even pushes you backwards in 5, so you'd have to calibur, snatch, or JC it regardless if you don't want to deal with the backwards momentum. You're kinda conflating the implementation of inertia in general with an instance of Nero's design just being the way it is. Besides that's only one of like two instances where you could maybe call it unintuitive. The only other instance I can think of it being stinger jump, but that's a pretty niche scenario that you'd have to put yourself in. These are like the only two instances in which a casual player can come across inertia and have it feel unintuitive, but truth be told that's not even scratching the surface of what inertia can do. The pros far outweigh two potential negatives. It's also really not that much to manage with everything else. You don't even have to actively implement it into your play style either. It's entirely up to you, as is the case with 99% of the game's combat. It should be there for the people that enjoy it and want to add an extra layer to their gameplay. It's not even difficult to manage it either. It's something you just utilize the more you play, the same as the other things you mentioned. Also not sure why you brought up stun values? Those aren't prevalent in 4 or 5 or really even something you can manage outside of DMC3. Inertia is already a positioning tool anyway, so you're not adding much more to manage. You just have more control/nuance over it, especially with Dante

Oh man, seeing DonGuri's gameplay right there takes me back, I remember seeing his fights and damn, he fights like a god, I'm no big time speed runner but I do like to try speedr unning every so often just because i love the chaos, DMC games in a way is the one that just makes me enjoy crazier battles in terms of chaos compared to a game like dragon ball xenoverse 2, it is why seeing dmc4 is probably going to be the most op types of gameplay you can ever see without any sorts of mods, dmc5 has lots of crazy stuff with it alone, but the fact that dmc4 was what brought creative chaos to such a degree, it's enough to make any warmonger and speedsters nut at absolutely satisfying gameplay fights like these, the trick to being able to play as crazy as this sometimes is to just enjoy and feel the game, like if you are looking at this from an outside perspective and it makes you think "I'll never be able to do this" your wrong, it's not impossible, you just have to be able to keep a cool head while trying to combo, it's kind of hard to explain in a way but think about it like literal "instinct" you get to the point where you don't even need to think about what button combination is the move, you just think about "what direction do i want to take the combat to" I'm still a long way from mastering the games but i have had moments where my mind is so clear and calm that i am pulling of crazy flying combos as well just from my head being like "ok this is the order i want to do this in" sorry about the paragraph but daaamn, i gotta admit if it wasn't for the physics in dmc4 we wouldn't be seeing crazy stuff like this all the time .

[@syrelian]

A lot of it is this simple mindboggling concept They don't think about the moves Combos like this, or speedrun strats and tricks, often come down to building a rhythm and muscle memory for the process or major parts of the process, so you just think "I'm doing The Thing" and Do It, instead of "I'm doing XYA XXYART XBAYY" or whatever and getting lost in your own inability to keep up, its also why when a speedrunner messes up a strat, they can often devolve to tactics similar to a casual player, it isn't necessarily that they can't do better, its that their rhythm is broken and thats disorienting compared to walking in prepared to do something less precise

[@c0mplex_Ale]

@@syrelian It’s like melee players really, there’s just so much crazy execution involved in playing it that they don’t even think about it. They build up thousands upon thousands of hours practicing and learning so when it gets to it, they don’t even think about what they are doing.
