ExTime: Primal Menace is a single-player action-adventure horror game inspired by iconic franchises such as Dino Crisis and Resident Evil. Travel to the archipelago in the Bermuda Triangle to understand the peculiarities of the temporal anomaly that brought the monsters of the Cretaceous period back to our world. On the way to the true reasons for the appearance of a time rift, an atmosphere of danger, various types of dinosaurs, secrets of the past, and an unpredictable future awaits you. Solve complex puzzles, fight, flee, and find out the reason for the events taking place on the archipelago.

Back in 1995, the research facility was built on the Scarsmore archipelago. Its prime task was to study the possibility of time travel. In the process of research, scientists discovered the so-called "principle of the reversibility of the past." This principle assumes that the object does not move in time in the state in which it is at the moment of transfer. Moving into the past - he is getting younger, into the future - he is getting old. That is if you travel to the past before the onset of an important event, and then move to the future after the event, it will not happen.

During the next test in 1995, a strong energy release occurred on the archipelago for unknown reasons, after which most of the base was destroyed and the project was closed despite all the prospects.

After 20 years, a scientific expedition is sent to the archipelago. During their stay on the island, scientists notice inexplicable phenomena that lead to sudden aging or rejuvenation of objects. After some time, the strongest release of energy again occurs on the archipelago, communication with the explorers' camp disappears, and the archipelago turns out to be inhabited by dinosaurs. Several leading powers create the «ARROW» organization, whose task is to clarify the circumstances that occurred on the archipelago.

Monsters from the past are very hungry and evil. Don’t hope there is a safe place, danger awaits everywhere—on land, in the air, and in water.

The atmosphere of tropical horror won’t leave you for a second: the chance to face a bloodthirsty reptile or a whole group of small predators is higher than ever. Also, don’t forget that the most dangerous creature on the planet is a man.
