Can't Unlock the Repulsion Cannon in Subnautica

The Repulsion Cannon is a Modification Station upgrade for the Propulsion Cannon. If it is missing, the usual problem is an incomplete tool chain or missing Magnetite and Computer Chip materials.

LAST CHECK

ANSWER LOCK // QUICK RESPONSE

First unlock and craft the Propulsion Cannon, then use a Modification Station to make the Repulsion Cannon with one Propulsion Cannon, one Computer Chip, and two Magnetite. There is no separate fragment set to scan for this upgrade.

SIGNAL CONFIRMED

BLUEPRINT DIAGNOSTIC // WHY IT ISN'T UNLOCKING

The Repulsion Cannon is a sidegrade made at the Modification Station, not a standalone Fabricator tool or two-fragment blueprint. A missing Propulsion Cannon, Computer Chip, Magnetite, or Modification Station will keep the recipe unavailable.

UNLOCK CHECKLIST

  • Build and access a Modification Station
  • Gather one Computer Chip and two Magnetite
  • Craft the Repulsion Cannon at the Modification Station
