Inferno Protocol

Inferno Protocol is a co-op survival horror game for solo play or up to six players. You explore a shifting maze in search of a way out, but its corridors change, and environments can become forests, deserts or frozen halls. You mark walls, leave objects as clues and rely on memory to navigate; a compass can help, but it is not always reliable.

Find your way

You can discover old hand-drawn paper maps, though some are misleading. Notes, warnings and sketches left by people who came before may offer useful information, point to injectors or exits, or warn you away from dangers. Their authors are no longer there to ask.

Survive the maze

Resources are scarce, and scrap metal and frayed wires only go so far. When you kill a creature, you can harvest its bones, armor, flesh and organs. You can also find traps or craft your own, then plant them in corridors and let the maze do the rest.

Settlements and survivors

A settlement at the maze's center lets you farm, build walls and craft supplies. Smaller camps are scattered through the corridors. Some inhabitants will talk or trade, while others may attack before you can draw.

Injectors

You find injectors as you venture deeper into the maze. Some are labeled with effects such as dash, rage, night vision, double jump and extra health; others are unlabeled. Injectors may save you or change you in ways you cannot predict.
