Phantom Abyss

Phantom Abyss is a massive asynchronous multiplayer game that casts players into procedurally-generated temples and tasks them with retrieving the sacred relics hidden within deadly chambers. Intrepid adventurers will dodge scores of hidden traps, leap treacherous chasms, and flee relentless guardians through branching paths until one of the relics are claimed or the devices of death overwhelm them. Be warned, you only get one attempt at each temple and failure or settling for a lesser relic means you will never see that temple again...

The cleverest players will use the phantom runs of failed attempts from other players to their advan
