Capture the Flag (or CTF for short) is a gamemode from Team Fortress 2. Both teams have to acquire the other team's intelligence briefcase and bring it back to their own base's intelligence room while stopping the enemy team from doing the same. Each time a team successfully captures the other team's intelligence, all currently alive members of that team will gain temporary crit boost for 5 seconds. When the intelligence briefcase is dropped, it will take 20 seconds to respawn to its original place. The first team to get to 3 captures wins the round.
