The 10th Planet

The 10th Planet is a cancelled space combat game that was to be published by Bethesda Softworks.

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

Development and marketing
Development for The 10th Planet began as early as 1994. It was showcased at E3 1995. The game was being originally developed jointly by both Centropolis and Bethesda. However, during the development phase, Centropolis chose to stop working on the game due to Centropolis's commitments to their films. Players who pre-ordered the game would receive a copy of XCar: Experimental Racing. The game was described as Star Fox meets X-Wing; PlayStation and Saturn versions were considered. According to Todd Howard, the game never made past pre-production.

Release
The game was originally to be released in 1996. This was pushed to October 1997 and later to 1998.
