Killingfloor

I play this with a group of friends and it's ALOT of fun. You have set classes which need to work together to kill certain creatures.

I would recommend it, but surely it's cheaper than 19 euros? :(

Get a group of friends to try it, loads of maps and theres a few different game modes! (Weapons are bad ass if your good at the game also)

just download and use garena

cool game, played via hamchi with friends
pure fun, lots of guns/maps, but just like 6-7 type of zombies

Pwning it with iN noobs.

rly a nice game :)

I would say, download it for free+garena!

Really good game but casuals ruin it
