Project SX-Ultra is a pulp-style interactive erotica game built with HTML by Kitty and the Lord. It presents an acid-novel story about a young volunteer who enters a government mind-control program and becomes an undercover agent. The Agency assigns missions that require deception, combat, and sex to survive in a dystopian setting. You explore strange worlds while dealing with cyber brain parasites, terrorists, rival agencies, and suspicious colleagues. The game uses AI CG visuals and includes themes such as female domination and male domination.
The v07.2026 build, dated July 3, 2026, shows continued development. It runs on Windows, Linux, and Mac in English and is uncensored. The update adds eight new Morgan GIFs, six Morgan images, and Morgan and Rhea TF quest events, including a Morgan date scene with three endings. It also includes new music for File 6 and the Neon Dreams Lounge, new File 6 choices for GEN FEM avatars, twelve exclusive avatar designs, a wardrobe in the Personal Portal, and an upgrade tree whose perks and abilities unlock through Quantum Influence. GIFs return for TF events, and players can ask Lucy about an intersex avatar.
