Description
The Propulsion Cannon is a versatile handheld tool that uses directed kinetic force to grab, hold, and launch objects at range. It is invaluable for clearing debris, solving wreck-based physics puzzles, and defending against small predators by hurling rocks or crafted projectiles. A PRAWN Suit arm variant extends the same functionality to heavy-duty operations.
How to Craft
Craft the Propulsion Cannon at a Fabricator after scanning fragments found in wreck sites. The recipe is modest, making it accessible early-to-mid game once you have Silicone production online.

How do I unlock the Propulsion Cannon?
Scan Propulsion Cannon fragments in wreck sites, then craft at the Fabricator with a Battery and Silicone. Fragments are commonly found inside wrecks in the Grassy Plateaus and Kelp Forest, often behind sealed doors that the cannon itself helps clear.
Can the Propulsion Cannon damage creatures?
Yes, launching heavy objects at smaller predators deals damage and can stun them. Rocks, metal salvage, and crafted items all make effective projectiles, though leviathan-class creatures are too large to meaningfully damage.
Can the PRAWN Suit equip a Propulsion Cannon?
Yes, the Propulsion Cannon Arm is a PRAWN Suit arm module variant of the handheld tool. It offers greater range and lifting capacity, making it ideal for clearing large debris fields and manipulating heavy objects during deep expeditions.
