Before Frictional Games became famous for its commercial computer horror movies, the team started playing Penumbra free of charge, which was later turned into a series of horror movies. Among other similar projects, this one stands out above all with its realistic physics of the world, which has been used in many ingenious riddles. In the darkness there is always something lurking, so you have to be on your guard.

After his mother's death, the hero of the game receives a strange package from his father, whom he has never seen before. In it he finds the key to the bank box, and in it strange notes about the secret base in Greenland. Without thinking for a long time, he sets off to an ice-bound land.

There he almost dies in a snow blizzard, but suddenly encounters a mysterious manhole. Happiness in misfortune, he finds what he was looking for. He needs to find out more about this place....

We are dealing with a 3D adventure, which means we need to run around different rooms and look for objects needed to move on. You can interact with the world at an advanced level. The cabinets can be opened by simply pulling the handle, the same with the door if they are not coded.

Move the boxes and barrels, and the petrol canister to the power generator by turning the cabinet. It soon turns out that the base is abandoned not by accident. Something here spreads on people.
