About Ad Infernum

✦ AI summary

Ad Infernum is a survival horror game where you navigate a desert wasteland filled with cult remnants and eldritch horrors while your sanity deteriorates through unpredictable psychological effects. Fight, hide, scavenge, and improvise your way through multiple solutions to each encounter, upgrading weapons and crafting items as your grip on reality slips away.

After experiencing a devastating car crash in the middle of the desert, you awaken stranded at a long-abandoned gas station. A voice on the radio calls out to you, trapped nearby but just out of reach. Together you discover remnants of a missing cult, unholy rituals, a mysterious cavern, and bloodthirsty creatures hunting you both down. With the walls closing in, can you follow in the cultist's footsteps and complete their final ritual -- before it's too late?

Lose Your Mind


Witnessing horrors will chip away at your psyche, depicted by your Nerve meter. As you slowly lose touch with reality, audiovisual hallucinations and other unforeseen consequences will begin to manifest. The effects of a weakened mind are wide-ranging and completely unscripted - meaning any manner of horrors can happen at any time.

Fight


Face threats head-on with a wide variety of guns and melee weapons. From hammers, to nailguns, axes, baseball bats, shotguns, and much more. All weapons are able to be upgraded to fit your needs.

Scavenge


Discover valuable supplies hidden away in every corner of the world. Use them at-will, or break them down in to raw materials to be used in arcane transmutation. Collect recipes to unlock the ability to transmute these materials into completely new items.

Hide


Avoid dangers by keeping a low profile. Create distractions by making noise, or take to the shadows to remain unseen. Flip switches or shoot out lights to gain the element of surprise, or power them all on to see what's lurking in the darkness.

Run


Escape your pursuers with a mixture of both agility and ingenuity. Vault over barricades, slide under obstacles, and climb anything to put distance between you and imminent death.

Improvise


No key for that door? Find a hole in the wall. Break a window. Crawl through a hatch. Climb up a pipe. Every encounter is designed with numerous solutions in mind, further multiplied by emergent systems allowing for completely new ways to tackle problems.

✦ AI summary

Ad Infernum is a criminally underrated horror immersive sim set in a demon-infested gas station that players praise for its clever puzzle design, creative problem-solving opportunities, and surprising depth despite its short length and small setting. Common complaints center on technical issues, particularly crashes on Linux, though those who can play it find it engaging with good replay value. Players generally feel it's worth experiencing, especially at a discount, as it delivers solid horror immersive sim gameplay in a compact package.

Ad Infernum is a short, yet dense, horror immersive sim with plenty of depth to pass the playtime. You play as an unnamed schmuck who finds themselves trapped in a gas station beset with a demonic presence. You need to carefully venture out from your safe room to find more resources, solve clever puzzles, and avoid the disgusting creatures prowling the gas station (at least until you're well-equipped enough to deal with them), while carefully balancing your health and sanity (the latter of which causes hallucinations at lower levels, brining to mind Eternal Darkness). The map is small (to be expected when the game is set around an otherwise typical gas station), but dense with supplies and secrets. As the game progresses, the demonic influence becomes more and more severe, until you find yourself in a true hellscape. After my 2 hour run, I was impressed by the game by the end. What it lacks in immediate presentation (somewhat simple graphics and limited voice acting), it more than makes up in game and level design. It was a blast to play, and the game does offer replay value as well with achievement hunting and a post-game currency to be used to strengthen your character for the…

Good and short game. If you are struggling, just improve a single melee weapon damage with all your kits and let that carry you.

Gameplay is tight, but the invunerable enemies are such a turn-off. This is not an immersive sim by any stretch. You can stack some boxes every now and then but you really don't need to. The game world itself is limited to about 3-5 buildings all of which are accessed through fairly linear means. Combat options and problem solving tools are too limited for this to be considrered an immersive sim. It's short, fun survival horror that will keep you hooked for about 3 to four hours. Play it. Play it.

A unique combination of immersive sim and survival horror. The systems and mechanics on the game are so solid that they would be great on a longer expanded game, but they are still as good in a 4 hour game. Respectable graphics, great music, competent voiceovers and story, and a creative setting that is larger than I initially thought. Overall, a great compact game that will satisfy both survival horror and immersive sim fans.
