  • 0:28 I c wut u did there

  • This game is great. Just get at least one friend to play with you!

  • That's actually pretty badass for a free game.

  • No one ever plays it.

  • @dragonsegg100 I do! No but seriously I can usually find a decent number of games when I go on. It's only been really dead like once in my experience.

  • Is this an FPS game or top-down game like some old games (GTA 1, GTA 2)??

  • "and a shipload of weapons"

    there really isnt very many weps :/

  • a very cooperative game. I recommend it! Unfortunately only one campaign. I wish for more.

  • Only Valve would make a game this awesome and release it for free.

  • this game rocks, as any of all valve games

  • I HATE THIS GAME! WHY? IT MADE MY LAUNCHER BEEN A PIECE OF SHIT

  • Seems nice

  • Isn't the guy at 00:34 the headcrab mom from HL1??

  • And offcoarse, windows only....

  • sadly, I downloaded this game only for the tf2 hat.

  • Odd choice of remakebut ok. it looks good

  • i just download it!

  • Gives it new Campaigns for Alien Swarm?

  • One of my favorites <3

  • holy shit guys, this is castle crashers with guns!

  • Do you have to play with friends?

  • GunBros Alien Version?

  • Did anyone notice that some aliens from that game are very similar to the ones in HL1?

  • @you0suck0popy one weird thing I noticed is that even though it's a source-based game, it needs to download Counter-Strike 1.6 too

  • why the f@ck always 4 player co-op ? >:( thats why killing floor is better than most games = 10 player co-op ! >:)

  • @thrallskull It has 6 players coop.

  • plz help me :( ive downloaded it i click play but its been saying preparing to launch alien swarm for the past half hour...what should i do?

  • Even though i´ve played through this, i almost shat my pants at the first alien.

  • looks fun!

  • It's a good game, or rather it would be, if the community wasn't so bad,

  • Hmm. Source SDK required the VC9.PDB.

  • The only reason why anyone plays this is for the worthless parasite hat.

  • @Animat8r i dont play TF2 and i play this game for fun like its dynamic shadows and shit like that the graphics in this trailer are true

  • yep. free on steam

  • Good game, but we all know 95% of the players are in it for the hat...

  • Its quite amazing that this is a free game, it is actually better than many games out there with high prices.

    Ive been playing more this game online than some i have paid for.

  • Very cool game! And free! Awesome! But it have so many bugs xD And no updates... sad.. and no Half-Life: Episode 3 ='(

  • Wow didn't think of getting this till today. Well new game for meh :D. Although is t just me or is it a bit like spiral knights? I mean the 4 players the screen and the mobs :/

  • @felliixs came way b4 spiral knights,,, originally it was for UT2004... so its older then spiral...

  • does this have any sort of Half Life connection? cus i saw one of the aliens from half life 1

  • @TheGravar No, there is no connection and no alien from Half-Life here.

  • @LuisMatheus4 0:34 that Alien is in Half Life 1, when u travel to another planet :)

  • @TheGravar nah it just kinda looks like it

  • @TheGravar You mean, XEN? As far as i know this game has no connection to Half-Life, unless Valve adds a connection to it in Episode 3 :P

  • @LuisMatheus4 no not xen, xen is that big guy in the end, im talking about that headcrab mother thing in half life 1 when u travel to the other planet, its the same on 0:34 xD

  • @TheGravar No, XEN is the planet where you see Gonarch, the Spider and Nihilanth is the last boss.

  • @LuisMatheus4 @TheGravar Yes sorry i kinda mix them up, but the name of that Spider Headcrab mother thing is Gonarch?

  • @TheGravar Yep, it is.

  • They look sort off like the monsters from dead space.

  • VALVe never fails to amaze me.

    Awesome work VALVe. Waiting to see where you go from here.

  • Any way to play it without acquiring STEAM?

  • @megamanxtreme2 I got mine through STEAM!

  • @MegaMaster456 So does everyone that has replied here. Thanks for the reply, but I don't like STEAM, personal reasons and I would like a way to get the game without having to use STEAM.

  • @megamanxtreme2 nowp its steam only.

  • @zakor33 Sounds about right, thanks.

  • better then l4d. make more

  • It's almost the Alien Swarm 1 year anniversary

  • @nelord7000 They do look a bit like mantis-men.
