Two teams play against each other. One team must escape by making it to a friendly base, breaking down barriers along the way. The other team must prevent them from doing so. The current version only allows you to play as the escapees.
Notes You can pick where you want your units to spawn by setting a rally point. The barracks contains units that are good at killing other units, the factory contains units that are good at destroying barriers, and the gateway contains units that are good for both.
