ANB_Seth is the solo developer behind Gunman Contracts, first as the Half-Life: Alyx mods Chapter 1 and Chapter 2, and now as Gunman Contracts – Stand Alone, published by 2080 Games. The standalone entered the Steam 250 seven-day chart at #41 in September 2026 with a score of 6.98 from 471 reviews.

His path is one of the clearest recent examples of a mod audience converting into a commercial one: rather than porting the mods, he rebuilt the concept from scratch to run natively in VR and on a flat screen, which is what allowed the standalone to reach players who never owned a headset.
