Very fun if you're good.
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
