To the ill-fated souls imprisoned within, ARX is a labyrinthine fortress of anguish and misery. But a single spark of hope within one brave spirit might just be enough to put an end to ARX's reign of malice.

Break the chain of torment

Many a spirit restlessly roam the halls of ARX. Awaken the soul of a foolish adventurer, of a humble servant or an untimely guest to try and earn back your freedom. To do so, you must venture downward, into the belly of the beast, in order to defeat the ultimate evil lurking in the catacombs below.

At the start of every playthrough, choose from a random selection of spirits, each carrying their own unique abilities and boons.

Into the fray

Angry spirits, enraged ghouls, bedeviled rats and many more guard your vengeful path to salvation as each hand-crafted, procedurally generated level becomes progressively harder the further you go. Look out for beguiling traps, secret treasures and snarky ghosts!

Relics and Weapons, and Spirits — oh my!

But do not fret - ancient relics, as old as the bones beneath your feet, will help you on your journey and might just give you the edge you need to succeed.

And should you happen upon a kindred spirit, try and help — you might be surprised by the result.
