However, a select few have pushed the boundary further by replacing assets or creating a level set outside the world of Half-Life, such as the Bioshock, Goldeneye and Wolfenstein 3D mods. We’ve tried out a bunch of Alyx mods and custom maps over the last year, most of which aim to create an experience and setting similar to the game’s main campaign. Gunman Contracts, a new Half-Life: Alyx mod by ANB_Seth, overhauls Alyx’s visuals to turn it into a mobster shooter that is almost unrecognizable from the game it started as.
