Tenchu: Fatal Shadows

Being a life-long fan of both stealth games and of ninjas, you put Tenchu into the disc tray. It takes it in, and fires a beam of dark light into your eyes. Everything goes black.

You wake up outside. You look around, finding only unfamiliar terrain. Standing, you see it looks an awful lot like a castle from old Japan, like on InuYasha or something.

Or in Tenchu.

'No!' you think. 'There's no way!'

Your doubt in what has happened is cut short by a female voice behind you.

"Where is Nasu?"
