The Warpgate is a large spawning point for each empire. Each warpgate has terminals where a player can change their class, spawn any vehicle in the game and switch continents. They are always surrounded by a distinctive shield that can be seen from a long distance away and can not be captured.
In addition to the warpgate, there are two smaller territories, also uncappable, which provide a small income of resources to prevent resource lock from rendering a faction unable to spawn vehicles after they've exhausted their supply.
Warpgates also have turret towers around their perimeter which can be manned.
Inside warpgates, players can't take damage from friendly fire or destroy their vehicles.
