Great game. Shame they didn't make additional maps and more content for it. That being said, I would have paid money for this game, but instead it was FREE! So, it was fun while it lasted.

Great fun with 3 friends - simple but fast paced and exciting. I wish there more stages/maps - too bad development stopped on such a frequently played game.

Two things about this game are mysteries to me.
1. Why the game so good is for free.
2. And why it's not as popular as it deserves to be.

I feel bad that people don't play this game anymore,if Valve made it a first person shooter it would probably be a lot more popular.But atleast you can make it first person with some console commands.Good game! ;)

First game I ever played on Steam, years ago now. Helped me come to accept that Steam wasn't malware :P.

Some people say that the community is dead, or bad.

It's not, there's still a large number of pro players active. Many welcome new players. Some times when you try to find a game, at that moment, there may be none available. Still plenty of people playing; each lobby holds 4 players, each game takes a few minutes. Every full lobby is invisible. People come and go. Consider starting a lobby yourself if at that moment you cannot find any players, it's rare for more than a couple minutes to pass without someone joining. If nobody ever joins your hosting, check your ports, maybe you're not set to handle hosting - that would keep people out of your game for sure.

Or just check for open games in 30 seconds or so. There's often quite a flux of players going.

Years after I started to play this game, I keep coming back to it. I like how the teamwork works, I like how the game is complex enough at the higher levels that I'm still getting better at it, even after so many hours of play.

If you have a few friends, and a couple of hours, you can easily blow through this little game. You won't regret any of it either.

Me: "ok what do we do now guys?"
Friend 1: "we put the bomb over there"
Friend 2: "ok then what"
Friend 1: "idk, something"
Me: "what is that timer?"
Friend 3: "RUN!"
other 3 of us: "what?"
we then proceeded to follow Friend 3 who led us in circles for some time before leading us into an ambush where we died before the bomb could get to us

9/10 If only it was longer

This is how i discovered this game
(me): wanted hats for tf2
(guide:) you need to complete 2 missions of alien swarm
(me:) "clicks download"
(me:) completes 2 missions
(me): finds hat on TF2
keeps playing dis game

SO i really loved this game but not many people play it and there should be more game modes
here are my suggestions:

survival: stand off the alien horde
escape: run from the aliens
plant the bomb: run into the horde while your freinds deafen i mean defend you
bughunt: hunt the boss aliens whilst tackling its freinds

I think Alien Swarm is a pretty cool guy, eh kills aleins and doesn't afraid of anything.

Actually though, this is a great game. Massacre aliens with up to three other people (and a lot more guns), weld doors shut to try and keep them out, cut doors open because oh-crap-you-have-to-go-back-through-there, and get butchered by the Swarm. You'll die. A lot. But it's super fun.

Alien Swarm is an amazing game you shouldn't play anymore.

This game was great, I played it constantly for a period. Gamplay was fun, fresh and rewarding, it was great either alone or in a squad, and it had a great asthetic. Murdering hoardes of aliens was so godamn fun, and the prestiege system was, while nothing new, a nice way of incentivizing.

However, I guess nobody gave the devs more money, or they simply misjudged the difficulty of content creation, or they just forgot the f2p elements, and this game slowly died. It had a great community, but you can only play one campaign so many times. People started leaving, and this game has kind of been lost to time.

Alien Swarm was a perfect example of a game, in many ways, done right. It's just sad to see it kind of fade like it did.
