Capture the Flag

Capture the Flag is speculated as a future Game Mode in Minecraft, mentioned by Notch in a Blog post. It is expected to come after the Final version of the game is released.

Not much is known about it, but, according to the name, it is expected that it will consist of players having to build bases and having to defend some sort of Flag from enemy players. The flag is most likely to be a new block type. Some people have made their servers have a sort of "Capture the Flag" mode where each team has a base, e.g. Red team has a red base, Blue has blue and so on.
