Open the "O2 CRITICAL Project" file in GameSalad for Mac, test/execute on companion device.
PHYSICAL COMPONENTS: Space shuttle game piece not necessary, but it makes the game a lot better. Storage card is not necessary, but it makes the game better. Game REQUIRES 8 black Energy Cubes, 12 colored Repair Cubes (4 yellow with 3 pips, 4 green with 2 pips, and 4 pink with 1 pip), 9 Oxygen Cubes (3 green, 2, yellow, 2 orange, and 2 red), and 1 D6 die (preferably the same size as the other cubes for easier rolling).
Technically speaking, the companion app isn't necessary at all if you know the repair requirements for each component and can keep track of your rolls. But, doing it that way really sucks (I tried), so using the companion app is recommended. But, I'm not your real mom, so whatever floats your boat is fine with me.
