The Bubble Gun

It is exactly what it sounds like: a Bubble Gun for R.E.P.O.

It shoots slow, floaty rainbow bubbles. If a bubble hits an enemy, it pops. If it hits a wall, floor, shelf, table, or other hard surface, it sticks there as a little bomb. Pop one bubble near another and they can set each other off.

How it works

Use it like a normal held weapon. It does not hurt teammates, and the tank does not refill on its own.

Contact	Result
Enemy body	Bubble pops immediately
Player body	Ignored
Wall, furniture, floor, or other inorganic structure	Bubble sticks in place as an armed static bomb
Nearby bubble pop	Armed and floating bubbles chain-detonate

The explosions are meant to feel punchy without turning the room into soup: light damage, solid enemy knockback, and big bubbly visuals.
