Aperture: Salt Mines

Aperture: Salt Mines is a community-made modification for Portal 2. Set in the same universe as the original games, descend into the heart of Aperture in the year 1998, shortly after the death of Cave Johnson. The year is 1998. You enlisted to Aperture’s test subject program a decade prior. As if only just remembered, your application gets accepted for one of Aperture’s standard testing courses. But what may seem like a simple hour or so taken from your day may in fact turn out to be a larger escapade than first thought.
