The Bio Uzi is an Alien weapon in Raze. In the game, you wield two at the same time. The weapon arcs as it fires a ball of acidic sludge at an enemy. If a player can use it the right way, a half-clip can kill most enemies.
The Bio Uzi's use canisters of highly condensed mixtures of Toxic waste and Acid. When fired, the mixture combines with the oxygen in the air, expanding it greatly and giving it it's watery nature. On impact with any surface, the mixture splashes and sticks to all nearby objects, corroding and burning right through them. Even the toughest of armors are no match for the Toxic and Acid combination.
