A long time ago, I was a child playing video games. One of the best parts about video games was the ability to modify the game. Change how it works, change the way the game was played, change the exact type of game that you played. Eventually modding got so involved that you didn’t recognize what you were playing in the first place, and along came those few gems, that were just delightful pieces of mods that made the experience totally worth it. What the.. frick.. (2008 ALL YOUR BASE remix) If that song doesn’t date when this was made then I don’t know what does. This is “Scientist Slaughterhouse”. Now, this game.. or this modification of a game, is off of the original Half-Life engine, which was made back in 1998. This mod was made in the early 2000s, I believe, and it’s entire objective, is about slaughtering the scientists in the game. I absolutely love this, and the game was discontinued, which is a goddamn shame. Well, maybe it’s not, maybe it’s not stupid fun. I haven’t played this in years. but what I remember of it, is that it was just absolutely wonderful. If you like the idea of those whacking games and the gratuitous violence that comes with it, then you will like this game, because that’s all it is. I swear. That’s all it is. You can shut up- Okay. There we go. Now- oh my god. Number one. It’s not even in the right resolution. Hang on, Lemme do this real quick. Alright, so if you don’t know what this is, and if you don’t know what Half-Life is, There’s… *Mark trails off as the site intercom says something unintelligible* I’m sorry. Oh, hi. Hello. There’s really nothing I could do to explain what it is. Oh yeah. Oh power me up baby. Oh, give me the juice! Yeah, I love the energy armor’s S U C C. Yeah, okay. Alright. Yeah, here we go. Yeah, it’s just- *wheeze* This is literally it. That’s all there is! It’s just a game with an entire infinite possibility of different ways that you can annihilate scientists from the game Half-Life. That’s it. Antimatter Pul- *mark breaks into laughter* pulverizer mode! *Mark unleashes fury upon a scientist* Ion Discharge Cannon Mode. *more fury* Gluon Gun! *less enthusiastic fury* Antimatter Puvl- alright, okay, so Yes- Oh! Shooty! (x5) male voice: OHMYGAWD, WE’RE DOOMED!! Yeah, oh.. I forgot there were scientists under the elevator- It’s been so long since I’ve played this particular “game”. Now I can- Now I can long jump. Yeah, I forgot there were.. *giggly* I forgot there were scientists down here.. I forgot! Okay, yes, so if you thought that was it oh you just have one gun and that’s gonna be it The answer is no whoa. Whoa. Oh Okay, you can shut down thank you, okay, what is this do I forget oh, oh, OHOHOHOHOHO There you go What does this one do? OH I see- hehehehe Oh my God! Incendiary warhead Ha-BOW! *laughing* PLASMA BOOOOMB! Oh my GOD! EMP, you say? EMPeepee *explosions* OHOHOHOHO You shouldn’t run into that my bud. Alright so Half-Life is an old game. Oh what is this? Ouu! Where am I? Oh I forgot there’s a lot of loading… The game’s old So like, you know how loading screens and engines didn’t used to be a thing It kind of is now- look at that sky box! We seem to be on an aircraft carrier of some sort. I’m sure this is normal. Wait. Hang on. Let me line up the crosshairs Hello! Hey, good to see ya. *gunshots* Okay… *chuckling* *Imitates gunshots and laughs* Oh alright that was- that was fun, that was very fun. That was fun. Test fire? Oh, goodbye. *laughing* Alright go go buddy, go go. Come on. Where you goin’? Where you goin’? Where you goin’? Oh shit! Um… I don’t think I was supposed to do that. I’m not sure how I get back now *laughing* I don’t think I was supposed to fall in… Ugh. Shit okay. Well, that’s weird. Is there a load? There we go. Okay back here I guess no this is fine moving on to a different area because that’s not where we want this piece button Oh Oh, oh oh, oh, oh oh oh, oh Oh, I see oh yeah, you should be worried. Oh I see. Oh I see God, I miss half-life! Half-life was this shit! I’m gonna say it outright half-life Was this shit one of my favorite games of all time love the imagination and my god valve. What are you doing? What are you doing? Half-life 3 you got to do it at some point you can’t leave us all hanging forever here, man Whoa, that’s a that’s a quake portal Hello What’s going on in there? Oh, that don’t look good. Well, that don’t look good at all. That’s probably one of those not good things. Oh no! Hi Don’t walk into the beam Don’t walk into the-. Well, you’re not gonna walk into the beam, are you? Hey, you shouldn’t walk into this beam here Whoa Okay, what’s in here? Ou! excuse me, Oh disruptive shield avoid contact oh ow! owie! owwww I didn’t know- AAAA! Hi buddy, hey, how you doing? I weeeeeee Aw, I lost my jump assist I lost it so goodly. All right. Uh-oh. Yeah. Yeah. Yeah. Oh Well, that’s not what I wanted. That’s not what I wanted at all. Can I get another one? Please pretty please put another scientist on the platform, please Aaaand squoosh. Shouldn’t be laughing at that I should but that’s what this game does to you Oh, well, that’s what this mod does to you it gives you a feeling of godly power the kinds that you shouldn’t actually have and yet you do, and I know not why I enjoy it so… Oh, what is this? It’s a flamethrower It’s literally just a flamethrower and then there’s a button… Huh? Oh wait [Scientist’s dialogue overlaps] Scientist: Why are you leaving me here…?
Mark: What a big baby. wHERE did you go?! Oh I didn’t do that. That wasn’t even me. Okay, caution extreme heat keep clear. What am I launching? Whoa. Oh Shit. Whoops. Bye. Be careful. You guys better. Be careful. You guys better. Be careful I think I’m getting Wallops about the volcano if I’m not mistaken. Oh, oh Oh Oh my god That’s why I should not have power in case it wasn’t obvious I should not have I just should. All right. Let’s get me out of here. I’ve taken a bit of damage I don’t want to do too much else damage to my poor innocent body. Oh Hi How are you? How are you doing? Not so good apparently according to your stump of a head Now what’s funny about this game? Is it got more sophisticated? The longer it went on like the more they updated the game The more sophisticated it became no one conquers the world alone for us Nothing is impossible like it seems weird to say but yeah the game did in fact become a lot more sophisticated A gas chamber? I don’t like the sound of that. Okay. Alright. Oh They just vanish, oh they just go into the ether. Oh, they just disappear out of this universe- What’s this do? What does this button do? Alright, so that’s pretty standard Okay, alright everyone do the flop, all right so cool good. Yeah so Nephilim, oh shit Nephilim wave. Oh Right They’re all so dancey, they’re excited The lure of of half-life is also just as bizarre as sometimes the game Thinking about the headcrabs and all that stuff and the combine and all hey Hey buddy. “Green emitter?” Oh wait ‘Please don’t mess with my laser turret.’ Oh, I wouldn’t DARE… How about you buddy? G-man. G-man! All right, whatever just back to you buddy, all right all your base are belong to us You have no chance to survive make your time All right. Good. Great. Yeah, good. Hey shaadi Gunny. What does this do? Oh, I’ll save you I Tried what? I’m sorry Hey, you didn’t tell me that was gonna happen Man, I got so many memories of playing half-life So many memories, I can’t even explain to you how far this brings me back because it really really does. Oh Shit. Oh Shit oh shit What does it do what it’s just to kill you it’s a kill you Oh, What the hell? Whoa, I bugged it. I- I most certainly bugged it. I bugged it. That’s not supposed to happen. That’s- that’s not- that’s not what you want. Oh!!! No Oooo tractor beam. Oh, yeah come with me Scientist: It appears that you need medical attention right away. Mark: I do…
Scientist: Let’s try this.
Mark: Ow. Yes. [singing] Baby I’m back! I’m on a roll, I’m back baby, Baby I’m back. Oh Where am I going, baby? I’m back mom. Oh Shit Oh, what is this? I know what this is. There’s a weird alien bug launcher, which I love Power overwhelming? Oh wait. Fuel. Oh, oh I get it Oh, I know what you want You want me to set up a bunch of things for you to get this to under waiver? Do this the thing in the stuff and that the thing you got it? Oh wow Snorks snark I’m back, baby Whoa shit. Wait, no no, no go back. I gotta get power overwhelming There we go What have I done Oh Oh Shit. Oh that that’s probably not good for the scientists outside. It is loud out there. It is really loud. It’s it’s quite loud. Oh, Shit. Oh My god Oh Weird weird. Oh, they’re fighting each other. Oh shit. It’s a war Alright cool goods war its war. I like war not really but okay. I’m out of here. Oh, okay. Good good Okay save what’s fantastic about mods and I kind of want to get back into the world of modding Especially modding way too much in games, which is always fun But the best thing about mods is it allows you to get more value out of individual games, you know You can have half-life 2 But it can last you a long Long time because so many people are in the community are making cool things like it just kind of never ends Whoo? That don’t make the most sense but whatever. All right what else we have here, what’s this kaboom? Oh Shit, what did I do? See, this is what it means it get more sophisticated as time went on this this mod was like updated month by month And so whenever they like added a new release to it. Hey You know they would do this shit for totally for free and it would just make game for the love of like making shit and I and I love that. I love that. It’s not sustainable in any way because people got to eat but man, I love hobbyist mod makers That’s the coolest stuff. It’s just so fun. It just makes it all really really fun And it makes games more fun because you can feel the community that’s all a part of it and you could feel how many people are like loving the game and enjoying the game and just like Hey, there’s something on your shirt. Hey your face Landed on you Where are you? Turns out they’re all dead. Okay, cool. I Didn’t realize it was like a wall of fire approaching you oh Omae wa mou shinderu.
(You are already dead.) NANI?! That’s still going on out there. Okay bear that’s I guess that’s just forever now Can I go turn that off because that is obsessively too loud. Oh my god Thank you, yes, thank you. Thank good God who vomited who yakked no emotion, dear do Alright, oh my [???] oh, oh What?! Melt your face! Oh! Oh My god I Love it. I love it really did get more sophisticated as time went on that. I don’t even remember that Maybe I stopped playing before it Was this one?

Oh, hey and nobody’s gonna get through ever again Okay, good good, you know and go.

Oh good at HEV. Okay brutes control Oh, Boots wait, no. I need to cross that I need it. I need to cross that please. Thank you. Okay. Goodbye I need that. Thank you. Thank you. Thank you. Thank you for that I mean it’s a scientist fault for just spawning out of nowhere Like if they didn’t just pop out of existence like that, then they wouldn’t have nearly the problem that they’re at it. Oh All right. I’m in here now wherever here is and there’s this thing. Oh No, wait. No, there’s no one in there. Oh All right, okay, you could still surprise me every once in a while you could still give me the old woofer Oh, hey is this gonna go spiraling out of control as the Rams over those scientists over there? Can I get up here, please? Thank you. Good look out It’s like this scene from Austin Powers You know how it was I Don’t need to quote it for you. All right, good road.

It hurts. Alright, cool. Goodbye How is there more? Oh hi.

Like they’re they’re cool sometimes in there They’re wonderful and they’re weird and I like that about them So thank you everybody so much for watching If you’ve got favourite mods that you’ve played in the past or that you’re playing right now for whatever game Please let me know down in the comments below I want to know what mods you guys go to all the time to have some fun with games that you know and love and have Played a bajillion times and you know mods make them a little more fun and you can always go back to it for a little Bit longer so, you know, that’s pretty cool.

Everything back there was either absolutely ridiculous and nonsensical for the fun itself or it was really deep shit with heavy story. Now, everything is fucking mediocre, reeks of vanilla more than classic wow and is fucking politicaly correct not to offend anybody.
