The Membrane is a gun that fires a shotgun blast of bouncing green bullets that split into more bouncing green bullets.
- Absent Minded - If the player also has Bouncy Bullets, The Membrane's shots bounce 4 times and become homing.
- This synergy is a reference to the movie The Absent-Minded Professor, which features an extremely bouncy material known as Flubber.
- Due to its overpenetration, high range, and high projectile count, the Membrane works extremely well with Flak Bullets and Scattershot.
- This works even better with the synergy due to homing.
- The Membrane is a part of the SHOTGUN gun class, and as such benefits from the Shotgun Affinity synergy.
- The bullets after the split will not be connected by Shock Rounds.
