Level 11 is a level in the Plazma Burst 2 Campaign. In this level, the Marine enters a medium-sized Civil Security base. In Level 11, the player encounters a new vehicle, the Mobile rO81-CS that charges from off screen, and endures heavy railgun fire.
The Marine approaches a Civil Security base. The first thing the Marine sees is a Civil Security Heavy armed with a Rocket Launcher CS-LitBro. However, as the Marine get closer, a Mobile rO81-CS appears from off the screen and charges him. After destroying the car and surviving the rockets, the Marine proceeds up a flight of stair deeper into the base. The player will find a few Crates along the wall. The Marine has to make his way through the base to reach the exit, but there are multiple platforms with Lites and Heavies armed with Lite and Heavy Railguns that could easily kill the player in 2-4 shots. There is an exit hallway on the right side center of the interior base, leading the Marine to the next level.
- Civil Security Lite - There are 15 Lites, armed with Lite Railguns and Heavy Railguns. A CS Lite inside the car has a Grenade Launcher.
- Civil Security Heavy - There are 5 Heavies in this level. Two Heavies at the beginning have Rocket Launchers, while the others have Heavy Railguns.
- Mobile rO81-CS - A Jeep with a minigun that charges from off screen at the beginning of the level. It has 120 HP on any difficulty, making it easy to destroy with 1-2 well placed rockets, or a single BNG blast.
