It's Christmas Eve in New York City! The mayor is throwing a wonderful tree-lighting ceremony, attended by many. He even has a disabled young boy to pull the switch to activate all the lights.
And as he pulls the switch, people notice that a lot of the crowd are decaying...
And New York City falls victim to a terrible virus that turns its victims into flesh-eating cannibals. This makes it okay to shoot them. The newly formed New York Bio-Hazard Team finds a sole survivor of an undead attack, one Officer Stevens. They find that Stevens is the only available person immune to the disease.
Even better, the normally invulnerable zombies explode upon contact with Stevens' blood. Things look brighter for New York suddenly.
This game provides examples of:
- Action Girl: The player, if one chooses a female Officer Stevens. Or if they select Rayne.
- All There in the Manual: Gives some background as to why you need to shoot up zombies with your blood - they're invulnerable. They've tried tanks, flamethrowers, rocket launchers, and they keep on regenerating... not to mention the only other thing that can stop them is a nuclear weapon.
- An Asskicking Christmas: Zombie hordes and Christmas trees. Yep.
- BFG: In the spirit of one-upsmanship, the game's biggest gun is the BMFG. Doom at least left your mother out of it.
- Bare Your Midriff: The female characters can wear outfits that leave their belly exposed.
- Bellisario's Maxim: Invoked by the manual, when explaining their rescue missions: "The civilians go into your... uh, 'backpack' (don't think about that too closely)..."
- Black Comedy: The Commissioner accidentally shooting a special-needs kid and his psychotic breakdown, flashing back to when he was locked in a shit-stained cell by an angry grocer who caught him stealing.
- The Cameo: Slipknot and Chimaira (the bands) are playable (and hardly expected additions at that). So's Rayne.
- Chainsaw Good: Zombie-Santa seems to think so.
- The Ditz: The Commissioner, who accidentally shoots a retarded kid and manhandles chemicals almost constantly. Even the Director of the NYBT says the Commissioner's son is smarter than him.
- Escort Mission: Comes in two flavors: Rescue missions, where you must collect civilians and lead them to a pickup site (later missions have the 'copters with limited seats, forcing you to head to different pick-up sites), and ones where you must protect civilians from zombies. The last mission was the latter with one civilian, the mayor's son.
- Mall Santa: what all of those chainsaw wielding Santa zombies were before the virus hit.
- Number of the Beast: Look closely at the blood paks used as ammo for the Vaccine Gun. "Type 666"
- One-Winged Angel: If you linger too long in a mission, zombies will go Berserk - turning into red-and-black humanoid things that move faster and do more damage.
- Our Zombies Are Different: See "All There In The Manual".
- Pyrrhic Victory: You've managed to save New York by wiping out all the zombies! Congratulations! Too bad you only saved a few hundred people, at least the entire continental United States is still zombified, and there's no word from the rest of the world. But still...New York! Ayyyy!
- Verbed Title
- The Virus: There's an interesting meta-game version based around Multiplayer. Each console had their own unique (cosmetic) version of the zombie virus. If you beat another player, then your virus would spread to the other player's console. If he beat another player, it would infect another save file from another player.
- We Are Experiencing Technical Difficulties: See above.
- Zombie Apocalypse: Duuuuuuuuuuuuuh.
- Zombie Advocate: Tom Reilly. He thinks zombification is "an eating habit" and organizes a zombie aid concert.
