TRAPPED takes place in Alaska, where a strange event has wiped out the entire population except for a few special people. Instead of water, a black, viscous substance has appeared, changing everything it comes into contact with. Poisoned swamps give birth to terrifying and deadly creatures. Previously, monsters were wild animals, but now they have turned into monsters that want to absorb everything they see on the way. The player will be in the role of a survivor, moving alone until he finds comrades. The authorities have brought military forces to the territory of Alaska, and the order is to destroy all living things.
