From the introduction:
Void Empires: 2750 is a game about science fiction adventures. The game ultimately revolves around a group people creating characters and having adventures such as: post-apocalyptic survival scrounging, battling it out with psi-blades and psi powers, marauding bug-alien hives, and epic battles in vehicles, mechanized walkers and space craft. Void Empires: 2750 aims to provide a toolkit that supports any of these adventures, for use either with the native setting or a setting of your creation.
Despite the toolkit approach of Void Empires: 2750, there are some core concepts that define the overall tone of the mechanics, technology, and the native setting. Below you will find high level descriptions of these core concepts, all of which can be easily changed should the GM wish to do so for their universe.
