Roll the control die. Aim for Amazing.
Alternity is TSR's skill-based science-fiction RPG: heroes are built from the skills you buy, and every check is a d20 control die plus a situation die, with Ordinary, Good and Amazing successes. Everything we can find about it is here — the rules, the settings, reviews, videos, fan-made PDFs and art, and where to buy the originals.
