one of these few games where you actually enjoy it with friends. Would totally recommend for a 4+ friend group looking for a game to play.

If you're looking for a fun shooter co-op game. This is your best choice. Been playing this game for years after years and never got bored from it. Apart from the original maps the game comes with, you can add more maps and mods yourself enhancing your experience even more! (I didn't try downloading any mod before though).
This is game is Half-Life but Co-op with your friends. Half-Life one comes with the game files, you'll find it naked hl_{lvl} in the maps. You can even play Half-Life Blue Force and other Half-Life varieties by just downloading their maps from the community and enjoy the laughs you have with your goofy friends and even family!
The best about this game it's free, doesn't require a strong PC, too many maps to try and the lobby limit is so big you'll almost never reach it!
