Styx and bones

The reaper returns to his apartment only to find it strangely silent. He goes to where the fireplace should be, and discovers that it's been painted over - there's nothing but a wall where it should be. His employer having left him, he decides to finish what the fireplace asked him to do and find the location of the skulls. While driving along river Styx to find the Stronghold, he stops his car as heavy skeleton activity in a construction site makes passage rather unsafe. Fourth level in the "Deadline" campaign. This one's a stealth level - use the dark and the silent guns to your advantage. Silenced 9mm pistol or tactical SMG are recommended primary weapons. Alternatively, there's plenty of loud and powerful guns if you want a more intense approach or if you just want to clear out the mines.
