Free This Week: Astral Ascent and Luftrausers on Epic, Steelrising on Prime

The Epic Games Store is giving away two games free to keep (claim once, own forever) until September 17: Astral Ascent, a fast roguelite platformer, and Luftrausers, an arcade dogfighting shooter. Both replace last week's Alone With You. Amazon's Prime Gaming, meanwhile, is handing Prime members Steelrising, a full soulslike action game (a demanding melee combat game in the Dark Souls mold), to keep permanently as part of its September rollout.
