Clan Arena is basically Team LMS (you spawn with almost all weapons as well) where 2 teams (red & blue) fight against each other. Once you die you have to spectate. If 1 team is 100% dead the other team gets 1 point. 10 points to win a map.

Helpful Hints and Tips
Team binds are again useful to show your position (e.g. “Roaming” bind on 8 [Numpad]) or to show enemy’s position.
