The 10th Planet is a cancelled game from Bethesda Softworks. It would have been a sci-fy space combat game, slatted for release in 1997. Playstation and Sega Saturn version were also planned.

In the distant future, our solar system is a ravaged battlefield, and mighty starship armadas are the tools of our destruction. Using a previously unknown tenth planet orbiting our solar system as its staging ground, an alien force plans on conquering Earth and destroying anything that gets in its way.
