Zombies are the least of your worries: Vampires, mermen, blobs, chainsaw-wielding crazies, and yes, spiders, are some of the more terrifying creatures that will also try to off your neighbors.

This neighborhood sucks.

Unused & Dummied Out Items

A few items and one weapon are unused, though unfortunately there's nothing unique about them besides their graphics. The Game Genie codes replace Player 1's starting weapon.


Still no bananas, we still have no bananas today

Game Genie code: KB2T-AAB6

The banana is functionally identical to the popsicle weapon, and uses the same graphics. In the Sega Genesis version, only the item's pick-up item remain. The SNES version contains graphics for the actual weapon and its HUD icon, but they were cleaned out of this version.

Paint Can

It's better suited for the SNES version anyway, there's a larger palette
This paint can is used in the SNES version, albeit obscured from the player's vision, and acts as the flamethrower weapon's pick-up object. There's no flamethrower weapon in the Genesis version, so its appearance here is even more confusing.

Yellow Potion

I don't want to drink it
Game Genie code: MK2T-AACJ

This is identical to the random potion. It's missing the question mark on the flask, but that's about it.


Items 5C and 66 point to the functionless Grey Potion and Machine respectively, at least in the SNES version. In the Genesis game, they don't even have any graphics in the ROM. So in this version, they're just blank entries with no icons and no purpose. Exciting!

Unused Level Bonus

This text appears in the ROM at address 987B:


While partially coded in, this bonus was never finished. It would grant 1000 points when a certain number of Blob monsters are destroyed. The Blob monsters can only be destroyed with cold weapons.

Unused Passwords

The following passwords are treated as valid, and will start the player in the bonus stage "Curse of the Pharaoes". Once the bonus is complete, the game will display the message "Dr Tongue welcomes you to 55 levels of terror" before hanging. The first code gives you all ten victims, with each subsequent code removing one victim from the total.


Similarly, these passwords are for accessing the credit level. Once complete, you will be prompted to enter a name for the high score (if you scored high enough to have an entry in the high score table). One of the NPCs in the credit level will give you the code QSDZ for all ten victims, however the codes for fewer than ten victims are never revealed.


Unused Music

Zombies Ate My Neighbors contains one unused music track. Interestingly, it's actually different from the SNES' unused track, and takes up a different slot! It's track 01, which points to nothing in the SNES version.

Regional Differences

North America Europe
VrrrrrrrrrRRRRRRRRRRRrrrrrr The perfect fireman axe

The Chainsaw Maniac enemy was redesigned into an equally insane Canadian lumberjack in the European version. Surprisingly, it made the transition rather well, behaving identically in both versions. Some related sound effects and text (such as stage names and a bonus related to it) were modified accordingly. (e.g. the "Chainsaw Begone Bonus" became "Axeman Begone Bonus".) This may have been done to prevent comparisons with Leatherface from The Texas Chain Saw Massacre, which was banned in England, West Germany, and other European countries.
