• Deadly Environments: get those best zombie locales as often seen in movies - graveyard with green gas-spewing crematorium, courtesy of "Return of the Living Dead"; lonely cabin in the middle of the woods; airports, junkyards, and more. In this game, the environment is your weapon. So get creative with your kills.
• Four Unlikely Heroes:
• Harlan Woods (heavily inspired by George Romero's "Night of the Living Dead")
• Natalie Flores (the tough but mentally unstable female lead; used to be a bartender)
• Ed Fragsen ( the lonely and broken security guard with nothing left to lose)
• Jimmy86 (the arcade rat-geek who's really a reflection of the designers themselves)

• Zombie-Killing Arsenal: flamethrowers, chainguns, dual smg's, shotguns, take your pick.
• Racking up the Score: score multiplier system plus bonuses
• 55 Days of Terror: 55 increasingly intense levels across seven unique environments in the game
