Level 13 is a level in the Plazma Burst 2 Campaign. In this level, the Marine encounters Advanced Usurpation Soldiers and Drones, making his way through a small outdoor area. The destination of this level leads to a teleporter which starts the Usurpation base levels.
The Marine begins at a drop-off down into a water area crawling with Advanced Usurpation Soldiers armed with Alien Shotguns. The first hostiles that are encountered are the Drones that will fire at the player as they descend into the water area. The Marine arrives in the water area and sustains heavy fire from Alien Shotguns. After taking out the Advanced Usurpations, the Marine crosses the water area on a platform beneath an even higher platform with more enemies that will fire down at the player. The Marine must proceed to make his way down into a pit below the main area of the level and teleport to the next level.
- Drone - There are 3 of them. These are equipped with Miniguns and Grenade Launchers. They attack the Advanced Usurpation Soldiers.
- If you are lucky, you can get the Drones to attack the Usurpations, possibly killing some. Or vice versa.
