The Stalker: Reborn

In The Stalker, you assume the role of an elite UNIT 8 soldier. You and your team have been sent to exterminate an "experiment that went horrendously wrong", known as The Stalker. He's a nearly invisible mutant hunchback creature with psychic powers, and he'll stop at nothing to devour you and the rest of your team. The goal is simple: Kill him or be killed.
