As part of a deal with Playboy, the game features a variety of posters featuring scantily clad models scattered about. And honestly, that's fair enough. Sometimes you really do need a bit of titillation after a long tiring day of shredding zombies with chainsaw-wielding motorcycles. We've all been there. But this product integration was not merely limited to the background. If you rescue a female survivor while holding an in-game Playboy magazine, you'll get bonus experience points. Creeping out the people you save is a plus, apparently.
To put the final cherry on this cheesecake, one of the in-game survivors comes with an appropriate outfit for a world-ending apocalypse: a Playboy bunny suit. She also happens to be the only survivor who cannot die before the finale ... because that would be removing promotional content from the game. The power of advertising (and boners) is stronger than death itself.
