MRFF

The fluid stream of the MRFF gun; the ammo-dependent length can be seen as a taut stretching toward the cursor

MRFF, short for Magnetorheological Ferrofluid, is a modded gun available in the n-gon mod n-gon-upgraded. It sprays a stream of fluid from the player's head which drains energy and has a length dependent on the player's current ammo.
