Mothership (Panic Engine)

Mothership, the sci-fi/horror game, burst onto the scene a few years ago and has inspired tons of designers to try their hand at a D100 system. It uses the Panic Engine, and the chargen ensures that there’s paths to min/max your build. It’s lightweight and powerful, and forces characters into tough decisions immediately. Tuesday Knight Games also sells third-party content on its site.
