Ad Infinitum is a single-player survival horror game set during World War I. Players take on the role of a German soldier navigating the trenches and haunted environments of the conflict while confronting psychological terrors and otherworldly threats. The experience blends exploration, puzzle-solving, and evasion of hostile entities across a narrative-driven campaign that shifts between battlefield ruins and a mansion in Berlin.
Gameplay
The core loop centers on first-person movement through claustrophobic spaces filled with mud, barbed wire, and decaying structures. Progress requires careful observation of the surroundings to locate items, activate mechanisms, and piece together clues about the protagonist's fractured mind. Encounters with grotesque creatures demand stealth and timing rather than direct confrontation, as resources remain limited and combat options stay minimal. Environmental hazards such as unstable ground and collapsing sections add tension during traversal. The story unfolds through discovered documents, audio logs, and visual hallucinations that reveal family secrets and the lingering trauma of war. Multiple endings emerge based on choices made during key sequences, encouraging replay to uncover alternate outcomes.
Game Modes
Ad Infinitum offers only a single-player campaign. No multiplayer options, co-operative features, or competitive modes exist. The entire experience remains linear in structure while allowing limited freedom to explore side areas for additional context and collectibles. Puzzle difficulty scales with the narrative, starting with straightforward environmental interactions and progressing to more intricate sequences that tie directly into the horror elements.
Development and Art Direction
The project originated as a student endeavor in 2015 before expanding into a full release. A dedicated digital artbook compiles dozens of illustrations and sketches spanning nearly a decade of work. This 79-page collection includes early concept drawings, development notes, and behind-the-scenes material that illustrate the evolution of the game's unsettling atmosphere and character designs. Screenshots and additional visuals provide insight into how the team translated the horrors of trench warfare into a psychological framework.
Is It Worth Playing?
Ad Infinitum suits players who enjoy atmospheric horror titles focused on narrative and tension rather than action or resource management. The World War I setting provides a distinct backdrop compared to more common modern or supernatural themes, with the psychological elements delivering consistent unease through sound design and visual distortion. Reception has been mixed, with critics noting strong atmosphere and story while some players cite repetitive sections or technical issues. The game launched in 2023 and received no major post-release updates or seasonal content, leaving it in a finished state available on PC and consoles. Those drawn to puzzle-heavy survival horror with multiple endings and historical flavor will find the most value, particularly if the artbook's developmental insights add appeal for completionists interested in the creative process.
