Steam Store description

What Lurks Inside is a tense, semi-cooperative role-playing survival game about exploring, destroying, and escaping a mysterious scientific facility… or about disguising yourself to sabotage and undermine the foolish humans who have wandered into your lair. Where to go? What to gather? Who to trust? Use your cunning and judgement to make sure that you make it out alive… Features: Play either multiplayer or singleplayer (Multiplayer Recommended) Random facility issues make each playthrough varied Environmental dangers Melee weapons and teamwork for human players. Fast-travel and traps for the monster. Set up a plan several rooms in advance, or lay in wait to spring an ambush. TRY TO PURGE THE LAB - BUT WATCH YOUR BACK… Four bodies in environmental suits descend into the facility… but only three of them are human. Which of your teammates is the monster? Cooperate with the other humans (hopefully) to complete objectives and purge the lab. SABOTAGE, TRANSFORM AND KILL! The humans have no idea what you’ve got planned for them. As the monster, use special Bio-Growths to fast-travel around the facility, setting up traps and plotting vicious ambushes. Pick off your companions one by one, or all at once in a grand master-scheme! Sabotage their equipment all while ripping apart corpses and collecting their bits to use later in feeding the Bio-Growth.
