Portal: Rebirth - Rebirth aims to create a unique Portal 2 experience based on visuals of both the first and second games. The puzzles will mainly be based on Portal 2 mechanics, and no word on the storyline yet. Please follow the mod to get updates on progress and story.
I decided to merge 00 and 01 to get straight to portal puzzles, this way it's better for the player that already knows the mechanics.
