Puff and Blow each have a Methane Gas Gun which fires a cloud of immobilising gas. If this comes into contact with a bad guy he will be absorbed into the gas and then float around the screen for a limited time. Bad guys are harmless in this state.

Puff and Blow must suck the floating gas clouds into their guns and blast them out against a vertical surface. Bad guys then turn into bonuses which can be collected. Be warned! – the gas cloud dissolves with time after which baddies become active again and extremely annoyed.

This is a PSP adoptation of Super Methane Brothers, a commercial Amiga platformer by Apache Software Ltd. The port is based on V1.4.8 of a linux conversion of the game by Mark Page.
