SPIRAL GALAXIES

Two opposing bases have been constructed around several large planetoids, their gravitational energy harnessed to power an array of transporter pads in the central core. Use them to beam yourself directly into the enemy base, but be careful, teleporters only work for the home team - you can't use them to get home! Each side also has two pads that can be used to move quickly to your upper level where a giant canon waits to launch you clear across the map. Defend your canon - because it is the only way back to the enemy base for invaders keen on taking your flag home, unless they want to ride the perilously slow floating conveyor pads that run between the two bases' lower decks.

Beware of orbiting asteroids.
