The CS-Autocannon is a large vehicular cannon that fires powerful bullets. It is manufactured by the Civil Security, and is intended for use by the Mobile rO81-CS, as seen in its color scheme. The CS-Autocannon fires large orange projectiles which explode upon impact. The Autocannon bears some resemblance to the Vehicle Cannon, which is also the source of the Autocannon's sound.
The CS-Autocannon is gray in appearance, and has four blue lights and one green light. When the cannon is fired, the lights slightly flash. The barrel of the gun is very similar to the one of the Vehicle Cannon.
- The CS-Autocannon was added as part of version 1.28, and was originally created by LazyRain.
- A handheld version of the CS-Autocannon was added in version 1.32. This version features a bolt handle, unlike its vehicle counterpart.
