Two sides, counter terrorists cts and terrorists ts, everyone buys same util and utils can counter each other, smoke extinguish molly and grenades can clear smoke, ts have ak and cts have m4a4/m4a1-s, game is very fundamentals heavy and emphasizes gunfights more than valorant. Since everyone is the same it allows every player the same opportunity for massive hero plays and outshine everyone else. There are still dedicated roles like in valorant, dedicated awper, entry fragger/duelist, support, roamer, and igl. Not much different from valorant which is expected since valorant esports started with washed up cs pros coming to valorant.
