About this game

GONE MISSING:

An Elite Research Team has gone silent on a mysterious planet possessing an inner, maze-like structure.  This is no longer a standard rescue mission; it is a frantic descent into a Shifting Labyrinth with hostile entities around every corner.  You are being deployed into the heart of this hellscape to determine their fate.

DIMENSIONAL DOORS

Once you enter The Labyrinth, you must navigate an endless assortment of rooms.  In each room, you have to locate a Key which can then be used to unlock Dimensional Doors.  These special doors will bring you deeper into The Labyrinth.

YOU ARE NOT ALONE

Many Dangerous Entities roam The Labyrinth.  You can choose to Fight, Sneak, or Run from these creatures.

Fight - Use your trusty Axe to tear entities apart.  While the most rewarding, this isn't always the most viable option, for many entities are impervious to any form of attack. 

Sneak - Crouching lets you slip by certain entities, though be warned; some entities are exceptional at tracking their prey.

Run - A first (or last) resort for many: Some entities are far too dangerous to take on, especially in groups.  Running away and losing them around corners may be your only choice.

TRULY ENDLESS

The Labyrinth will go on For Eternity, becoming more and more dangerous the further you wander.  With every attempt, you can aim for a new high score on the leaderboard.  Additional challenges can be enabled for extra points.

What horrors will you encounter within The Labyrinth?
