Release Date: 1993
Platforms:  SNES, Genesis
Developer: LucasArts

Not really an obscure game, but still probably not as widely played as it should have been.  From one of best game developers of all-time, Zombies Ate My Neighbors is a quirky but difficult game that forces you to try and save the world from an invasion of zombies, mummies, vampires, and gigantic babies.  Weapons include water pistols, bazookas, and everything in between.  Each level is self-contained but generally detailed and fun to look at, with locations ranging from beaches, to museums, to pyramids.  The game also combines horror and humor at the same time and does it quite well.  And because it's LucasArts, there are about 40,000 easter eggs to be found as well.  The soundtrack is also quite catchy, with appropriate tunes for each themed level.

My favorite part of this game has always been co-op, even though it possibly makes the game more difficult.  But it's a blast to go through this hilariously crazy universe with a buddy and a drink.  "Now, get on the trampoline and jump over to where I am.  No, not that direction.  Damn!  Now I have to backtrack and do this all ov...oh crap, alien!  Die!"

There is apparently a download available for the Wii, which is the SNES version.
