Русская рулетка - Russian Title
A ring of planets, connected by galactic portals has become lost in space. The planets are devastated and the portals have been disassembled. It is up to you to you to find the missing parts of the portals so they can be reactivated. Mostly you will have to fight for them, or perform services to the local authorities.
You can exit and enter any vehicle you encounter at will, and many have turrets that can rotate independently. In some levels you will be accompanied by an NPC who will guide you to the next portal part.
