Touching an enemy gives them and their nearby team mates the plague. Plague victims bleed to death in 10 seconds unless they pick up a health kit or touch a resupply cabinet.
Increased max health, small health regeneration, small fire and reload rate increase. Attributes shared with nearby teammates.
Discharge your supernova attack (grapple secondary fire) to briefly stun nearby visible enemies. Stunned enemies drop their powerups, and are pushed away from the supernova attacker. Once discharged, the Supernova powerup disappears and respawns.
