About Ad Infinitum

✦ AI summary

Ad Infinitum traps you between a decaying family manor and the hellish trenches of World War I, where you must uncover dark family secrets and battle grotesque creatures spawned from your fractured psyche. This psychological horror puzzle-adventure uniquely blends intimate personal trauma with the cosmic dread of war, forcing you to distinguish between nightmare and reality as you fight to break an endless cycle of suffering.

Trapped between the walls of your family home and the trenches of World War I, you try to piece together your past and take back control of your life.

BREAK THE CYCLE



Will the nightmare of the war ever end? Will you find inner peace one day? In Ad Infinitum, you play as a German soldier haunted by the horrors of the Great War. While your mind grapples with memories of your family home and the trenches on the front, you try to break the endless cycle of suffering.

BETWEEN A DREAM AND REALITY



You wake up in your bedroom, unchanged from your teenage years, in a run-down and deserted manor house. Suddenly and inexplicably, you are transported to the trenches where the horrors of war are overshadowed by vile and even more terrifying creatures. Unable to distinguish between reality and nightmare, you must fight to regain control of your life's narrative.

NIGHTMARES THAT BECOME REAL



Unspeakable nightmares come to life in the recesses of your mind. To escape the death traps and terrifying creatures, you must understand the source and motivation of each monster and solve the puzzles that stand in your way. From blind demons who can hear your softest footsteps to hideous disjointed puppets who move in the dark, horror is around every corner.

A FAMILY TORN APART



The fallout of the war is felt far from the front. Peel back the shroud that hides the secrets of your family, torn apart by the Great War, and try to remember your past. Through exploration and by solving riddles and puzzles between the walls of your home and the barbed wire of No Man’s Land, you ultimately reveal a chapter in the story of a German family torn apart by war.

✦ AI summary

Ad Infinitum is an atmospheric horror game with solid storytelling and aesthetics that players compare favorably to titles like Layers of Fear, but it suffers from notable bugs including broken puzzle elements and progression issues that significantly detract from the experience. Most players acknowledge the game has merit in its concept and design, though the technical problems and frustrations they cause make it a risky purchase even at discounted prices.

A story that is dark, beautiful, thought provoking and confusing. Would recommend at a reasonable price.
Recommended Sep 25, 2026
This game was both incredible and terrible at the same time. The bad is that it can be buggy around ladders and some of the set pieces are almost perfect but fall just short (not all of them but some are anticlimactic), As for the great parts about this game it dives into World War I possibly the most horrific war humans have ever waged. Brutal and without mercy showering the lands with toxic gases, artillery, and gunshots that turned once beautiful land into a place no man should live. Shell shock was given to many soldiers who survived the horrors of trench warfare and the game's horror reflects that. Going over many themes that can and will hit a little too close to home for some this game tells a great story both on and off the battlefield, If you like slow burn psychological horror games this barnburner can be right up your alley and if so I'd say it's worth playing. There are definitely times that come really close to perfect but fall just short but that doesn't take away from what the game is trying to push the player into experiencing. I'd give this game an 8/10 but objectively I can see it being around a 7. Great game nonetheless.

Incredible atmosphere; simulataneously terrifying and heartbreaking. There are so many layers and I'm glad I played this. If a game was ever poetry, it would be this.

Amazing game, beautiful soundtrack, good graphics! Give it a try and if on sale it is a must buy!

Games like Borderlands 3: guns that roll, trees that branch

Games like Borderlands 3 have to do two things at once: roll a new gun every few minutes and make a skill tree worth planning. These manage both, and one asks you to craft instead.
