Zombies Ate My Neighbors is an action-packed monster-mashing shoot-em-up that has slithered out of the SNES and into the Genesis. One or two players fight Zombies and other famous movie monsters that have overrun 48 lengthy labyrinthine levels and seven hidden bonus levels!

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.

Error Handler

Exclusive to this version of the game is a basic error handler. Handy! Use the Game Genie code ABTA-B92C to trigger a 68000 Error in the demo.

The complete list of error traps starts at 2D60 in the ROM.

Hidden Text

Banana

Supraball legendary items. 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

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

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.

Miscellaneous

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 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

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.
