This variant of Erosion is a rocky asymmetric map set alongside a sheer cliff ledge.
Ascent is built on the terrain outside the Grifball court on Erosion. It has two bases, the red base at the top of the map, and the blue on the opposite side, at the bottom. The map is littered with rocks for cover. In the middle of the map, there is a neutral Wraith among many buildings.
- It is the only built in competitive forge map not to appear in matchmaking.
