Road to Promageddon

This free to download, barebones game aims to be playable in one session, but is also robust enough for replay and modification. It isn't part of any pre-existing tabletop RPG family tree, though it is in Creative Commons (more details at the end of page 2), so if you ever feel the urge to put your own spin on this prom themed mech joy, take a stab at it.
