Hidden Palace presents...

Spore (Feb 19, 2008 prototype)

Discuss this release on our Discord server!
And check out the Twitch stream as it happened!

Happy New Year everyone! We start off with a big bang. The game Spore has been famed for its lengthy development and the many iterations it went through. Today we present a build, donated by a generous anonymous secret Santa, dated Feb 19, 2008, a full six months before the final release.

It features many cut creatures, features, debug editors and overlays, a planet editor, a cut flora editor, an animation viewer, a model viewer, and much more cut content that is sure to make the Spore modding community busy in 2026.

Enjoy!
