Okay, so as I just said, there's two different endings to the game.
You would think that just beating the game would give you a normal ending... and you'd be partially correct, this ending does give you a staff roll. But remember, your character is a diabolical Eater. So what exactly happens?
(as for those weird discolored parts of the background in outer space... I'm not sure if it's an emulation issue or Jaleco being lazy. It IS a prototype, after all...)
So what went wrong with Chimera Beast that would cause it not to see the light of day in arcades? It's hard to say, as there is no information anywhere that I can find about the game regarding this.. It's my personal theory that players were turned off by the ugly player sprite and perhaps the ugly graphics in general... or they didn't grasp the concept of eating the enemies. Who knows? If the game had actually been released though, I don't think it would've been too big a hit, so maybe Jaleco was right in cancelling it after all. But I'm glad they took a chance in developing the game, for even though it may not have ever officially seen the light of day, emulation has provided us the opportunity to forever preserve this gem and see what could have been.
The game certainly isn't perfect though... truth be told, it's really not some of the best gameplay ever to hit a shoot-em-up. So why DO I like this game so much? Truth be told, I think it's that wonderful "bad ending". God, what a delightful twist... of course I realize that I have completely blown the surprise if you've read this far, but... chances are you were never going to play the game anyway if I hadn't told you about it personally, so... yeah. If you're in the mood for a "different" type of shooter though, I highly recommend giving the game a chance in MAME or RAINE (since you'll never be able to play the game otherwise), you might be pleasantly surprised.
In the Mankind stage (Stage 6), destroying the jeeps that are on the ground make a pair of humans appear... they don't really do anything, they're just fodder to be eaten.
But wait... they MAY look familiar if you're well-versed in the ways of shitty arcade beat-em-ups!
....oh, that's right, it's a reference that pretty much nobody would catch or ever care about. Still though, it makes for a fun trivia fact, doesn't it? Not surprisingly, a lot of the same staff that worked on 64th Street went on to create Chimera Beast, too. It all comes full circle!
