I stuck upon a guy in a Russian forum that claims to have a different version of the Abe's Exoddus game in which there are some significant differences in the level design.
He has only the first disc of two so the game can not be finished but it's a interesting one.
I don't know if this version is known among you and if someone have hearth of it.

Here is a screen comparison

I sent him a mail asking if he can share it.

By the way since it's a first post here ...
I'm curious about what are the chances of finding a prototype of Prince of Persia 3 (aka Kindred Blades) shown on E3 here [url]http://www.youtube.com/watch?v=KUyLOVmKu4E[/url]
It's more violent then the final version - The two thrones.
Kind of closer to WW
