this is my second favorite counter strike. there are awesome gamemodes to play, and you need it for garrys mod to work properly... if u can, buy it!!

this game is so amazing. there are so many hilarious endings and funny easter eggs in this game. there are portal and minecraft ones... must buy this!!!

this game may be really old, but dont let that fool you. stil one of the best fps's out there lol. actually not sure how much it is, but its worth it!!!

i played this game a lot with my friends. its fun to work together in this fps/strategy game. I reccomend this to people who like coop games.

This game was just a game i bought cuz pewds played it... but this game made me laugh so hard! There are so many jokes and secret stuff!! Must buy!!!

this game is amazing. the only thing i dont like is that HALF LIFE 3 ISNT OUT!!!!! THANKS VALVE!!!!!!!!!!! lol but no this is an awesome series!

i have barely played this game, but from what i have played, it is an awesome coop experience to play with your friends. Must buy if u got good friends!

i really like this game. i honestly have not played much of it but maybe at least 10 hours, and from just playing on like 2 servers, and there more!

I think this game is amazing because its not just a first person shooter, you have to communicate with your teamates, and work together. "100% NOT COD"
