Gameplay
This map is multi-layered and symmetrical, and purpose-built for competitive CTF matches.

Trivia

 * Swarms of lumenons can be seen flying in the background. Rarely, a glitch can make them fly across the map, but the scene does not appear when reviewing the match in Theater.
 * A small creature can be spotted on Red Base and Blue Base, lifting a panel. A good way to spot it is to zoom in with a Sniper Rifle as it hides away when you get too close.
