This battle takes place on a hostile planet with an unbreathable atmoshpere. The sound of your air system is audible throughout the mission, and the noxious gases are visible as a green haze and fog. Even the sky is a sickly green color. Fireballs leap up out of the lava below, and the occasional lightning strike can be seen as well. The bases are rather near to each other, but perched on opposite sides of a small valley. To get to the enemy base, you can either jump across the platforms suspended between them, or run across the bridge far below, or circle around the ridglines at the ends of the valley. It makes for a fast-paced and refreshingly different battle.
