Corrosion: Machines Change Minds

User summary: The game master creates and controls a self-aware machine that attempts to exterminate the characters. The remaining players have human characters that attempt to survive and (possibly) triumph. Action resolution uses opposed dice pools. The game uses an ingenious character sheet that is cut into nine pieces, each representing an intersection of character capabilities. When characters sustain damage one section of the sheet is flipped over, eliminating a die from their pool for that intersection.
