Chasm: The Rift

Humankind, in the process of evolution, has encountered a mysterious phenomenon - the destruction of the normal flow of time. From the past to the future, time rifts are forming in Earth's atmosphere. These rifts lead to different periods of history. Through them the most aggressive creatures from the past, present, and the future, have begun to infiltrate our time.
