Download of Vanish 1.0 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X is a product of 3DrunkMen. We recommend checking the downloaded files with any free antivirus. The application lies within Games, more precisely Adventure.
From the developer:
Vanish is a first person adventure horror game for Mac. Thrown into a Labyrinth for reasons unknown, you must roam through the darkness to find your escape. It's dynamically generated at run-time and continues to change while the player plays it. Each hall piece dynamically spawning and certain objects within it as well, with a possible burst pipe or idle creature.
You may want to check out more software for Mac, such as Shiver - Vanishing Hitchhiker, Shiver - Vanishing Hitchhiker Collector's Edition or krank, which might be similar to Vanish.
