Very fun if you're good.

User Rating: 8.8 | Counter-Strike: Source PC
This is my favorite multiplayer fps for the pc. The guns are nice, the graphics are nice, and most of the lvls are designed for strategy so they are always interesting. A big part of what makes this game good is that you die in about 2 shots, 1 if it hits your head. So if you cant aim fast and predict your enemy's actions you're not going to enjoy this game. Two of the only quibbles i have with this game are-
1. Everyone is a camper. Everyone on the terrorist team camps literally every round and its really not fair or fun to fight against ppl with that kind of advantage. Luckily the counter terrorists usually arent allowed to camp since they are on mission to save the hostages. Oh, also the awp completely overpowers every other gun in the game so never play on servers that enable them.
2. So many hackers.....the second a server has no admins the aim botters come and ruin a perfectly good playing session. Also i have reason to believe that about 30% of the cs population either uses wallhacks or recoil hacks, not that i really care about these cuz im so quick to shoot it really doesnt help them much B-) the end :D
