An Unofficial Half-Life Expansion Pack [Delta Particles]

Here's a half hour long video of me yapping about Delta Particles. It is a mod for Half-Life that was released fairly recently, and I loved every bit of it. This is almost the same length as Blue Shift and that's why I call it "an unofficial expansion pack".

Her accent makes it even more immersive. Of course a top lab like Black Mesa would have geniuses from around the world, not just the US

[@Web720]

While true, but for a top secret research lab?? I could see immersion from with or without that cause it can go both ways.

[@dylanv.4970]

I really like the line in Black Mesa mentioning that the facility employs people from 5 U.S. States and 3 countries or something to that nature.

[@SysOpQueen]

@@Web720 very true, a lot of 'surface level' top secrets are marked NOFORN meaning literally "No Foreigners" such as the operations of nuclear plants. Easy security clearance for a native born citizen, a whole different story for anyone born outside the country edit: but don't give up hope! plenty of comrades who share ;)

[@theicepickthatkilledtrotsk658]

The mod's dev sure likes grey and purple. It looks good though.

[@designator7402]

It's a tricolor scheme that's pretty smartly used. Allies and safe spaces are purple, orange is used as a guide/attention color, and green accents mark enemies.

One thing I realised from modding Left 4 Dead 2 is that weapon sounds heavily affect how good a weapon feels to use. The dual pistols feel bad to use normally since they are weak and have weak sounding shots, but they feel great to use when the sounds are replaced.

[@tonny8881]

A good example is RTCW MP. The thompson and mp40 were the same stats wise, but people thought the thompson was better because it sounded better

[@pellaria8012]

The beretta sounds weak in half life.

[@thornknight8402]

left 4 dead 1 had better pistol sounds

[@Pinnaporaptor]

I remember playing this one back when it was just Half-Life: Delta, had a super good time with it. Looks like a replay is in order

[@DoctorBreenBB]

Speaking of mod things, SMG got silencer upgrade later in the game, electrician NPCs can "heal" player like scientists, but they restore armor instead of HP, and in Xen you can kill these Xen Trees which smack you and was indestructible in base HL. Btw killable Xen Trees was my contribution to this mod, I did killable Xen Flora, code and basic gibs models, but unused that since I didn't do any full fledged mod yet (expect some skins at Gamebanana) and shared it with author, same with running zombies, I did that animation, (its edited HECU Grunt running anim actually, which I was able to load on zombie model, and modified hands so they look forward instead of holding invisible weapon), liked how it played, they are more fun compared to base HL where zombies are almost harmless enemy to be honest, and showed this animation to XF-Alien, he liked idea and added them as separate zombie variant, which replaces average zombies randomly based on difficulty.

[@karisasani7006]

As for his way of saying, "It couldve had combines come to apprehending you" at the end... would you have done that?

[@DoctorBreenBB]

​@@karisasani7006 I don't like this idea, I don't think that it would be any sense to reference HL2 or other Valve games even if they share same universe if mod story isn't connected at all, and I'm not related to ending at all, I'm not mod author, I did some contribution, its just Xen Trees and running zombies, same as coder of Field Intensity mod helped mod author with coding some things, but main developer is XF-Alien, and everything including models, animations for them, maps, story, most of coding, almost everything is his, and he did ending as he wanted to. And if even if I was main mod developer, I'd still won't do that.

[@uncanny-hector-1906]

THANK YOU for making the Xen Trees killable. I didn't know until I accidentally blew one up.

[@Lucios1995]

There's t w o technicians in the entire mod

[@EugenijusKrenis]

I love all this fanon and unused content (like Hostile Takeover) stuff with competing research corps and etc, Black mesa, Aperture, etc etc, a major competitive field wxisting for decades and then it's still 90-00s as usual with all this hypertech like power armor, esoteric energy generation, robotics and teleportation being relegated exclusively to the very facilities and a military detachment here and there.

[@BOGI1703]

This mod is so 2000's in the best way possible I love it 🔥

[@ivanthehighman177]

26:01 actually at this part and the sections before where you start seeing space, in my head canon, you legit went to a telaporter that telaported you even outside of Xen and space and time.

[@jess648]

xen in this mod has the vibe of some of the concept art for it

[@Cats-TM]

We salute you, Security Man. You have done great work for your research facility. 19:20 Hey! It is like German Half-Life!

23:23 Bro I just love the atmosphere here man. The devs did a perfect job with it.

[@cepheus3d]

It's a really fun full conversion mod. The slower gameplay compliments Half-Life's gameplay really well. Very tastefully done, even with a limited budget. I really wish we'd see more of these kinds of projects cause they're so cool!

[@parkmallbaby]

There were so many fun HL1 mods I played back in the 2000s. One of my favs was the mod where you play as a Vortigaunt I think it was called Point of View, and Paranoia where you play as Russian Spetsnaz who uncovered some old Soviet biological weapon experimental bunker. Those mods were so well made. And there was also one set during the Vietnam War with some horror aspects to it.

[@Torekk]

Propably one of the best youtube videos ever, it tells you exactly everything you need in about 30 seconds. I'm gonna dl Delta Particles now.

[@Atrahasis7]

Man what a golden age of fan made content, HL Echoes, Field Intensity, Signal Lost, Residual Point, for HL 2 the excellent Entropy Zero 2, and this is only one franchise. Other ones have been getting amazing stuff as well. I dont like the detail textures on this but looks fun.

[@dylan8736]

[@starwatcherusa]

I just recently completed this mod. It's really impressive how long it is for it's quality. Almost feels meandering at some points. Although I LOVE how it completely recreates almost the entire arsenal and it has the most beautiful version of Xen for a goldsrc mod i've ever seen.

[@Samiska19]

[@m4pownerz]

Thanks for the mod recommendation, Radiation Hazard. Brilliant as always! Love from Australia.

[@franthehonest-eyes4883]

When I want more Blue Shift, I use to play Azure Sheep, even if it contradics with what's behind the locked door that Barney is knocking, apart from that it's a beautiful and entertaining one to play. It has an hq model pack but I would recommend not replacing the apache model because it causes an error with the first scripted event.

Cant wait for "Half-Life: Delta: source"

[@Cats-TM]

After a bit of thinking I think the SMG is a Heckler and Koch UMP. Would need to play through and see a world model but I have yet to have time to do that. So, this is my best guess based purely on the viewmodel shown in the video.

[@ecksdee1149]

after just 57 seconds of watching this video you convinced me to download this mod so far i love it

Realized i wasnt subbed to you when someone in a sven coop lobby mentioned you, and i was curious about this mod too since delta particles made a big splash in a hl1 mod discord im in but i wasnt too particularly impressed from what was discussed; you definitely sold me on this mod in the end

[@alface935]

6:35 That Machine Gun reminds Me of the Ump from Counter Strike 1.6 but with more gear

[@charity_]

dunno if you noticed, but once you fight an assassin, your SMG gets a new silenced option... lower speed, high accuracy, its fun :)

The Combines Arresting the Main Characters would have been sooo awesome. That would open up Room for a 2nd Part and would also be able to make the Story Continue

[@matheusgraef]

this mod looks so GRAY. sometimes i felt like it could have used more varied lighting to "paint" the rooms in different colors since everything is a gray canvas.

[@Feasco]

would you say it's grittier and less bright?

[@impairedtrout6917]

It's because it's dark and gritty

This whole thing feels like an alternate universe Half-Life 2 where they did just make a by-the-numbers sequel to the first game.

[@unimportantcommenter4356]

Played with the Delta mod and I have to say that it was very impressive for a quote on quote "demo". Thabks to your vid, I'll try Delta Particles out cause I just can't get enough of the game's buttery smooth gunplay. Also, is there a chance that you will cover HTDF: Classic? Unironically looks like "Mod of the year" material to me.

Will check out HDTFC. It always slips my mind.

[@mr.pointman1930]

And Lambda Generation as suit voice is awesome.

[@dojodog]

What immediately stood out to me in this mod was the sound design- the team went above and beyond. I was very pleasantly surprised when I first picked up a health kit or battery and the chargers were extremely satisfying to use, especially after a huge encounter. The punchiness of the weapons makes them feel extremely powerful, which really helps the weaker weapons in the arsenal feel a lot better. The damage output on some of the weapons is also pretty insane, even on hard mode; The M4 consistently kills HGrunts in about 4-6 shots and the Barret is really good for taking out Alien Grunts quickly.

[@saltypotato42]

It's a really good HL mod. I love the map layout and visual, also the gun sound is a plus, compared to HL. I hope there's going to be more mod like this.

[@intecrisis]

I did really like delta particles but I maintain that residual life is the best hl1 mod ever

[@ivanthehighman177]

[@Theocatzipped]

Good mod, played it yesterday

[@TheSeriousSoul]

I just finished playing this mod myself the other day and I put off playing this mod until after this video. I disagree with the Light Gun doing the most damage of any weapon in the game, I'd give that to the monkey wrench. Reason being is I one shot the tank with it you see at 19:30 by holding down right click for 10 seconds almost killing me in the process. I found the Xen part to be only difficult due to a lack of health rather than ammo but I did wrench the majority of enemies due to it's instant kill capabilities. Also the "Ghost Zombies" seen at 15:30 are actually headcrabbed female assassins as seen by the corpse you step over right after killing the zombie. Fun mod and was definitely good enough to keep me absorbed from beginning to end.

[@commenter_HIMIK-MAN]

Oh hey, I played this mod before it's full release. There was so much content in it that by the end, I completely forgot it was unfinished. I should replay it, seeems like they added a whole lot since.

[@HellsAsylum]

Nice mid. Kinda reminds me of Hostile Takeover and the Allied Processing facility, although Allied Processing wasn't competing with Black Mesa as far as I can remember. Btw french fries on pizza is god tier.

[@NoVIcE_Source]

Dr. Diana Hayes Nerd lol

[@kokojack]

I played it when it was known as Delta years ago (2022) and it was good but nothing crazy. It felt like a russian reboot of Half Life with new setting and new weapons but it was cool. Some fights were very, very hard due to lack of ammunition, xen controllers and assassins everywhere, very high HP ennemies, switching between weapons was awfully slow and mobs spawning en masse in front or behind you. I did love the xen part it was long but very well crafted Judging from your video, the mod added more weapons, was visually improved, added decapitation, new ennemies and a better ending. You didn't mention the low switch speed animation issue so I assume it was fixed. I rated it 7/10, but with those changes I would probably give it an 8 or even a 9

[@staticsphere_]

22:28 in all fairness he was foreshadowed by some audio cues and this section is also notably devoid of enemies to build up the anticipation. That being be said I also shat myself here.
