In RHEM is a letter I have written to my brother. If you help me get this letter to my brother ZETAIS I can help you get back to your world.
A rich and complex place with its own rules.
On a quest to uncover the secrets of a mysterious letter.
A journey - you arrive, a stranger in a strange land.
When you start the game, the opening movie will run and you will be transported to the land of RHEM. The car has been commandeered and you must sit tight in one spot, momentarily unable to leave.
