This is a Sci-Fi themed variant of the original Basic Action Super Heroes! game. The basic mechanic is rolling 2d6 and multiplying the result by the appropriate stat (Brawn, Agility, or Mind) plus any applicable modifiers and beating a target number. Simple and easy. Characters are built on points. While there are plenty of options here, it won't take you hours to build a character and you could jot all relevant stats down on a 3x5 index card. This version includes guides for creating alien races. There are also rules for starship combat. Scenarios range from Victorian Steampunky Sci-Fi to Sci-Fi Fantasy to Post Apocolyptic genre.
