How the heck does this ONLY have 17 votes; it's the better version of Altered Beast. In fact, I dare say it's exactly what Altered Beast ought have been! There's a definite lack of games where you can transform into animals, and frankly, with the existence of the furry community, I'm surprised there's not more games where the player can transform into animals.
We have that Animorphs game for the Gameboy, Altered Beast, Mythic Force, and Bloody Roar... (I'll even add Silicon Valley Space Station as an honorable mention.) And that's it. I'm sure there are more obscure titles too, but this is the icing on that cake. Please bring back MYTHIC FORCE for those of us who missed it at the arcades!
