Any good 4-player co-op games?

[SoSicklyAwesome]

Me and three of my friends are looking for a 4-player co-op game that we don't already have, but nothing comes to mind.

So, I'm following one of my many mottos:

"When in doubt, come to Facepunch,"

and asking you guys if there are any awesome co-op games you know that support 4-players or more.

We already have Payday: The Heist and DEFCON, so please don't mention those.

Cheers!

Left 4 Dead or Killing Floor.

Left 4 Dead 2

the mass effect 3 demo is fun

[Lazyboy0337]

League of Legends is fun, but you would need five people or work with a randomie.

Wait, that came out and I didn't notice?

I'm ashamed of myself...

You should check out SWAT 4.

[Creeper]

Swat 4, Serious Sam, Borderlands, Sven Co-Op.

Alien swarm is quite fun, and its free.

[Jax Strife]

DUNGEON DEFENDERS! Also: Magicka, Terraria, Any of the ARMA games, Titan quest is a good co-op RPG, same with dungeon siege games. Multiwinia is fun but competitive.

We did have a Dungeon Defenders craze, but that did not last for longer than two months.

Far Cry. Make the right map and it's hours of fun.

We're thinking of getting EYE: Divine Cybermancy.
Should we?

If you guys like strategy games you can try Men of War series,specially Assault Squad

But I'm not sure if you can really play with 4 friends,only tried with 3

[stoyan377]

L4D,L4D2,LoL, Dota2, Borderlands, Alien Swarm, Killing Floor, Bunch of Heroes, Magicka, Portal 2 (for portal 2, only 2 people co-op).

i wanted to say Cry of Fear.. but you want a "good" co op game

[Muracle]

Borderlands and Dungeon Defenders are great.

Hey man, if it's so bad it's funny, we'll have a blast playing it.

[catbarf]

Left 4 Dead, Serious Sam, System Shock 2, Doom 3, Serious Sam, SWAT 4, Serious Sam, Borderlands, Alien Swarm, Serious Sam, Serious Sam: The Second Encounter.

But really Serious Sam is about as good as it gets for co-op FPSes. It's simply awesome.
