Portal: ISOLOPHOBIA

An experimental, "open-world" Portal 1 map inspired by images of "Elegiac" or "Liminal Space" vibe. The map has no real 'end', the player is encouraged to explore as much as they wish.

Install Instructions: Extract the BSP and place it into your "maps" folder in Portal 1, then load up the game and load the map via the console, play for as long as you wish.
