Cabin in The Woods

We are in Norway. You are working for a global organization on a classified project and you decide to take a road trip with some of your colleagues on the mountain Swalbard, to explore the forests with the most secret bunkers. Rumor has it, that there lies the global treasury, deep in the mountain, where the most essential things of earth are kept, to be used by those who outlive a global extinction. In your path, trying to avoid clashing with an animal, your vehicle slams on a tree and is immobilized. Unfortunately, no one in your group has mechanical knowledge and your phones have no signal to call for help. So you start to walk, hoping to find civilization or someone to help. A few hours later you bump into a cabin deep in the woods. You approach and knock the door to ask for refuge and help and that is the last thing you remember. When you regain consciousness you realize that some of the group are no longer with you and leaving from where you are seems almost impossible! Will you be able to figure out what happened and escape before the night falls? The clock is ticking…
