Capture the Flag - Steal the enemy's flag and take it back to your base.
Attack and Defend - One team tries to take control of a map by taking their flag to certain points in a map. The other must prevent this from happening. If teh attacks manage to take control of all the points, then the roles are reversed.
Territory Control - Two teams vie for control of points scattered throughout a map. To take control of one, a team's flag must be taken to the point. Once one team has control of all of the points, the points reset.
Hunted/Assassinaton - A Civilian must reach a point in a map, but asassins (usually Snipers) try to stop him. HWGuys, Medics and Soldiers assist the Civilian. If the Civilian is killed the assassins get points and the map resets.
Deathmatch - Kill everyone for fun and profit!
