Abe's Exoddus Demo is a shorter version of Abe's Exoddus release before the full game. It's currently available on Steam. The demo only lasts until the point just before the Brew Drinking Cutscene.
Similarities and Changes
The Gamespeak functions are all identical to their final versions. The title screen is exactly the same and the controls are the same. Most screens are also identical.
You can only access Abe's gamespeak on the titles screen, Several screens are changed. For example the screen which says 'Quicksave! And be glad you did!' is replaced by an empty screen. There are also less tutorials.
The most noticeable change is the removal of the game's quicksave feature. In addition, the save function is broken so that no saves past the screen before the above mentioned room work. Trying to load a save beyond this point crashes the game and invalidates all the other saves.
The demo ends when you activate the seven wheels at the end of the first area, which then provides you with a slide-show of a number of screens of the full game, before closing the demo.
