Red vs Blue. Romans, with their Coliseum, versus the Greeks, and their Parthenon, in the ultimate clash of civilizations. 3 strongholds are setup and so are all flags that are required.
Game mode: ScatterCaster (strongholds) is perfect for this map. Similar to paintball but not one life, and you get the scattershot and the plasma caster.
Paintball = Golden Gun = min health/one shot kills. Also, no friendly fire.
