It's Like They're Popping Out Of The Screen. (Sorta).

In order to promote the (anaglyphic and stereoscopic) 3D support in its upcoming rails-shooter, House Of The Dead: Overkill - Extended Cut, SEGA's released a couple of new screenshots of the game that work with those cheap red and blue glasses. Try it out.

Given the game's grindhouse vibe, this is actually pretty authentic. Nothing says 'retro' quite like a pair of red and blue glasses.
