Capture the Flag

Capture the Flag is one of the game modes planned to be added to Minecraft. You are most likely to be split in teams, to build a fort and defend your flag. No other information has been leaked.

A popular mod by noxyryan has been made. In it, player scale maps, and tag each other if they're on their side, and use TNT to explode other players optionally. There is also a flamethrower which spews scripted lava blocks.
