About Ad Infinitum

Ad Infinitum puts you in the mind of a German soldier haunted by World I. You awaken in a run‑down manor that mirrors a teenage bedroom, then are thrust into the brutal trenches, where history and horror collide.

The game mixes exploration, puzzle‑solving and combat as you uncover family secrets and confront nightmarish creatures. Its core question is whether the endless cycle of suffering can ever be broken and inner peace found.

01 / THE GUIDE

Dream‑Reality Shift

The protagonist wakes in a deserted manor that looks exactly like his teenage bedroom, then is abruptly transported to WWI trenches. This shift forces the player to treat each environment as a distinct narrative space.

Both settings contain their own obstacles: the manor hides riddles tied to family history, while the trenches expose you to combat and surreal monsters. Recognising which world you are in guides how you approach each challenge.

  • Take note of visual cues that differ between the manor and the trenches; they often hint at puzzle entry points.
  • When the scene changes, pause briefly to reassess objectives, as goals differ between the two realms.

02 / THE GUIDE

Nightmare Creatures

Unspeakable nightmares manifest as blind demons that can hear the softest footsteps and disjointed puppets that move only in darkness. These entities add a horror layer beyond the historical battlefield.

Survival depends on learning each monster’s behaviour. Blind demons react to sound, while the disjointed puppets move in the dark. Understanding these patterns lets you avoid death traps in both the manor and the trenches.

  • Listen for subtle audio cues; they often precede a blind demon’s movement.
  • Be cautious when entering dark areas, where the disjointed puppets are known to move.

03 / THE GUIDE

Family Puzzle

The fallout of the war reaches the soldier’s home, where family secrets are concealed behind riddles. Exploring the manor and solving these puzzles gradually reveals the story of a German family torn apart by conflict.

Each solved riddle links personal memory to historical context, providing narrative depth. Solving these puzzles unlocks new story fragments that flesh out the family’s past.

  • Document clues you find in the manor; they often reference family members or wartime events.
  • Cross‑reference symbols on puzzles with any historical notes you encounter for clearer interpretation.

04 / THE GUIDE

Single‑Player Experience

Ad Infinitum is designed for solo play, allowing you to progress through its story at your own pace without multiplayer elements. All narrative and combat content is accessible in this mode.

The game includes full controller support, meaning you can use a gamepad for both puzzle interaction and combat, though no other input specifics are detailed.

  • If you prefer a controller, experiment with its layout during early puzzles to find a comfortable grip.
  • Take regular breaks to absorb story details; the pacing rewards reflection.
