Xenopopper

The Xenopopper is a Hardmode, post-Golem gun. It uses bullets as ammunition, but fires a small cloud of four bubbles per shot, which pop after a short delay and release bullets that travel to and intersect at the cursor location. It is dropped by the Martian Saucer boss during the Martian Madness event. The Xenopopper's best Modifier is Unreal.
