—Blast your way out of tentacle hell as a failed lab experiment gives birth to a rapidly growing viral horror in this intense action rogue-lite inspired by 80s Monster movies. Use the lab to your advantage and improvise an escape plan before this constantly evolving life form spreads out of control.
Demon Spore
SteamAs a top scientist at a cutting edge genetic research laboratory, you’re racing to solve the problem of feeding an ever growing population. Your team is overstepping ethical boundaries with gene editing in an attempt to breed a new form of livestock that will grow at 100 times the rate of normal animals.
But after an experiment is mysteriously interfered with, it gives birth to a virally spreading mass of tentacles that is consuming everything in its path and evolving into a creature from hell. You must use your scientific experience to learn how the organism behaves, exploit its weaknesses and fight your way to safety.
An abomination of flesh and tentacles with a taste for organic matter, constantly evolving and adapting, spreading to consume everything in its path. Use any tools you can find to slice through the creature’s tentacles, target its weak spots and stunt the growth. Escape each floor before the growth mutates into something even more horrific.

Team up with friends in local co-op mode where up to 4 players can attempt to escape the lab together. Choose your character and role carefully and watch each others’ backs - you’ll have to work together to survive this tentacle infested hell.

Use your scientific know-how to re-purpose lab equipment and systems to slow down the growth or create a diversion. Manipulate the lab’s layout to lock doors, create new routes and block the creature’s spread. Cobble together experimental weapons and technology to fight your way to safety in an ever changing environment.

Every room reveals new surprises and tough choices. Sneak past the creature before it spots you or set a trap to swing the fight in your favour? Save a scientist to unlock new equipment or cut your losses and race to the exit? But be careful - even your fellow scientists may be unknowingly carrying a dormant growth waiting to release itself…

Each path has different dangers and different rewards, choose your escape route wisely to stay one step ahead of the creature. Every time you play you face a completely different layout but will learn more of the secrets of the lab and how to use them to your advantage to outsmart your enemy.
