Team Fortress 2
In Capture the Flag mode, the map is split into two nearly identical bases; one for each team. Both bases have a briefcase in them. The goal is for one team to grab the other team's briefcase and bring it back to their own base, while defending their own briefcase. You must capture the enemy intelligence 3 times in order to win the game, but server modifications can alter the number. When a player carrying the briefcase is killed, the intelligence is on the ground and returns to its base after a 60 second time period. The player who dropped the intelligence or his team can pick up the briefcase before it returns and still capture it. If a player drops the intelligence by falling into a bottomless pit, it automatically returns to its base. The briefcase can also be manually dropped.
