The Mobile rO81-CS is a fast, armored car-type vehicle developed by the Civil Security, and found in the Plazma Burst 2 Campaign and singleplayer, but can never be used in multiplayer like other vehicles. It is first encountered in Level 11 and becomes usable in Level 18. The Mobile rO81-CS has great ramming skills and speed, and can easily run over enemies, draining their health and usually outright killing them. The Mobile rO81-CS can be hard to control in terms of speed, and can easily be destroyed if it collides with objects at high speeds. The Mobile can easily be flipped over onto its side, and cannot be returned to its normal driving position without the help of explosives. This inconvenience makes the Mobile rO81-CS difficult to operate in many situations.
As for the appearance, the vehicle consists of a body curving inward around a glass-like dome, where the vehicle driver operates. There is also a spoiler and multiple exhaust pipes on the rear. The armament is connected to the side of the cockpit. Two large wheels can be seen on the ends of the vehicle, giving the Mobile a similar appearance to the PB:FttP Jeep.
As mentioned before, this vehicle can run over enemies, and can run any character over. It's also possible that if the floor is thin enough and a player is run over, they can slip out of the map and die. The same is true for enemies. It is also possible to glitch the mobile if it hits a surface hard enough to the point that its wheels will appear above the vehicle.
Enemies in Mobile rO81-CS mainly charge off-screen, especially in the Campaign. These powerful vehicles will run the player over and crush them if they are not careful. When destroyed, the driver will be ejected automatically. Like the Hound Walker-CS, the player can take control of this vehicle by getting close to it and pressing the E button. The main weapon found on the Mobile is the Vehicle Minigun, which is also used by Drones.
- A different model is seen in Plazma Burst: Forward to the Past. It is highly unlikely to be a Civil Security Mobile, due to no other Civil Security technology being seen in the game. This could be a Human Soldier variant of the Mobile.
- A speed test has revealed that its speed down hill is faster than a bullet.
- It appeared 3 times in Plasma Burst 2 campaign: once in level 11 and twice in level 18.
- If you shoot it with a Drone Gun CS-Virus blood will squirt out, killing the operator and disabling the vehicle, resulting in a dead body falling out. Once dead the vehicle will become neutral and usable, no matter your team.
- Note: Before the version 1.17, it was not possible to takeover a vehicle after killing the operator.
- Unlike the Hound Walker-CS, the Mobile rO81-CS's movement is relatively silent. No motor sound can be heard.
- When the Mobile accelerates in Time Warp, whether it is in use by the player or an enemy, the speed will increase greatly, and the car will have a very large chance of flipping. The player can avoid this by braking slightly to cancel the flip.
- If your Mobile collides with an enemy when Time Warp is activated, the enemy has a greater chance of dying and breaking from the impact.
