The "bubble" shooter.

"bubble" shooter is a trap created by noob scientists. It shoots "bubbles"(cannon ball code name) at mutants. The noobs have ran out of bubbles so now it's just standing as a decoration. How does it works : you put "bubbles" in the back of the shooter and then it shoots out from the front cannon of it.

Random Comment : This sadly was a weak machine that they builded, in 1990, they builded this because it was able to kill mutants, they had some poisonous bubbles into it and that basically killed the mutants and so they coughed and coughed until they died of the poisonous gas going through to mutants lungs, and that happened but the bubble shooter doesnt work anymore since the noobs are out of poisonous bubbles.
