Vodolazik: a lost crew member from the first Titan expedition. Heavy radiation and an unexplained biological exposure may have caused his mutation. Original fictional lore and artwork; the name and pressure-suit horror inspiration acknowledge Project K.O.N.T.U.R., without affiliation or endorsement.

Original monsters inspired by Doom and classic 1990s shooters, using our own designs rather than Doom artwork. No affiliation with or endorsement by id Software or Bethesda. Original Titan map and Lumen monster sprites/designs by Lumen SI for Valentyn Shapovalov/SREIF. Doom-derived engine via doomgeneric under GPL-2.0; actor movement/projectile routines adapted from that engine. Freedoom Phase 2 supplies temporary pickup, projectile, font, UI and sound assets, credited to its contributors. Original synthesized action OST and Titan Breach ambient track by Lumen SI, with source in compose.py and music notes. Mashenka is an original adult-sized synthetic maintenance entity: she stops advancing and cannot strike while a living player faces her within a 90-degree cone with unobstructed sight; she moves and attacks when unobserved. No eye tracking is used. Vodolazik’s betrayal, space-radiation mutations, spore/light attacks and 2035 expedition are original Titan fiction, not scientific claims or external canon. No commercial Doom II WAD assets are bundled. This is not an id Software/Bethesda product. Mobile controls are experimental.
