Acid Cannon


The acid cannon is similar to the pistol, musket, and energy pistol in that it repeatedly shoots projectiles at regular intervals. The projectiles in this weapon are acid globules. Note that the acid terrapus is immune to the acid cannon in all its versions. The acid cannon is the weapon of choice for destroying the skeleton terrapus and any type of Automaton.

It can be upgraded using a weapon kit. When upgraded, the name and appearance of the gun will change along with increased damage output. The upgraded versions are mark II and mark III.
