The Immortal Lock

You are Ranger, an operator of the UTJR stationed at a secret, multinational research facility in Finland. You are being deployed to investigate the disappearance of a survey team that went missing beyond the slipgate, cast into the farthest reaches of existence. Yet through the thin veil of reality, you find only a desolate plane of flesh and despair, and a dread voice that beckons your name. This map is larger than an entire episode, if played in its entirety, and is best experienced in segments. It includes a story, extremely challenging fights, trick jumping, and a vast amount of large secret areas, but is difficulty scaled to accommodate everyone.
