Gravity Kings is a cancelled overboard / overbike racing / skateboarding game that was in development by Microsoft Game Studios for the original Xbox. Unfortunately there are basically no details on this lost project, but just a few images from an early prototype: by looking at these we can speculate it could have been similar to the Tony Hawks’ Pro Skater games (exploring the levels, doing tricks), but with an alien twist. The game was set in a modern-looking city, but with strange, orange-skinned aliens.
Images from this early prototype are preserved below, to remember the existence of this cancelled game. If you worked on this lost project and could help save more details, screenshots or videos, please let us know!
