Propulsion Cannon

The Propulsion Cannon is an Unimplemented tool. While it cannot be crafted players can spawn it in-game using the ITEM PropulsionCannnon command

It has an energy level which can be replenished with a battery.

One of its intended uses is to launch DNA serums.

It can also pickup and launch objects, such as peepers, sandstone, and Debris.

Speculation
The Propulsion Cannon looks ALOT like a Gravity gun, it also seems to pick up debris from the Aurora, possibly hinting that there may be hidden things under the debris of the foresaken ship?
