What Lies Within

ENTER THE FACILITY. COMPLETE THE ASSIGNMENT. GET OUT ALIVE.
What Lies Within is a 1–4 player co-op horror game where you work as contractors for M-E-L — Mutation Evolution Laboratories, entering abandoned research facilities to recover what was left behind.
These facilities once housed experiments involving extra-terrestrial lifeforms, genetic manipulation, viral mutation, and human testing.
Now they're unstable, decaying, and filled with the remnants of M-E-L's work.
M-E-L doesn't care how you get the job done. They only care about results.

EVERY DEPLOYMENT IS DIFFERENT
Explore procedurally generated facilities with changing layouts, rooms, hazards, objectives, and entity spawns. Each facility environment rotates through multiple states, including blackouts, flooding and more. Routes you relied on before may no longer exist. Learn the facility, remember your escape routes, and adapt when your plan falls apart.

COMPLETE YOUR ASSIGNMENTS
Repair systems, recover classified research, document entities, collect biological samples, and complete special assignments issued by M-E-L executives.
Your team must recover enough valuable material to meet the research recovery standard set by the M-E-L executives.
Success increases your promotion level, bringing greater rewards—and greater danger as well as a higher recovery standard.
Repeated failure will result in termination.

YOUR VOICE CAN BETRAY YOU
Use the in-game radio to communicate with your team while exploring the facility.
But be careful.
Your teammates may not be the only ones listening.
Entities can react to the sounds you make—including your voice.
Sometimes calling for help is the worst thing you can do.

SURVIVE THE FACILITY
Every entity has unique senses, behaviours, strengths, and weaknesses. Some hunt by sight, while others follow sound, investigate disturbances, or track your movements.

Observe them. Learn how they hunt. Bring specialised equipment, find places to hide, and use the environment to create distractions.

Adapt—or become their next victim.

Welcome to the team.
