Wolfen were the pinnacle of scientific achievement, redefining the limits of what it means to be human. Their counterparts, in turn, grew into the ultimate predators.

In the game of survival, Wolfen were created to win every time. But while the enemy keeps evolving, rendering old tactics ineffective, the only rule left is to endure at any cost.
