The Castle
A massive steel and wood castle with two 20 foot turrets scalable by spiral staircases. The structure is surrounded by a speedball type field containing barrels and tyre barricades for cover. You need some serious skill to attack and capture this stronghold.
One Team attacks the castle, the other defends it. If an attacking player is shot he/she must walk back to the top of the field, where they can then join the assault again. The defending team must hold the attackers back until they ultimately are all destroyed. The game is played twice (once each way) and the fastest attacking team wins.
