The official site for Neil Marshall’s Doomsday has been updated to include a new 3D game as well as a restricted-content area.

The restricted content includes an image gallery and two videos, “Under Attack” and “Street War.” The site also now has a 3D game called “Maurader Massacre.”

Doomsday, which stars Rhona Mitra, Bob Hoskins, Adrian Lester, Alexander Siddig, and Malcolm McDowell, hits theaters March 14, 2008.

Synopsis: In the action-packed new thriller DOOMSDAY, from writer/director Neil Marshall (The Descent, Dog Soldiers), authorities brutally quarantine a country as it succumbs to fear and chaos when a virus strikes. The literal walling-off works for three decades—until the dreaded Reaper virus violently resurfaces in a major city.

An elite group of specialists, captained by Eden Sinclair (Rhona Mitra), is urgently dispatched into the still-quarantined country to retrieve a cure by any means necessary. Shut off from the rest of the world, the unit must battle through a landscape that has become a waking nightmare.
