This might be an obscure one, but...
Metal Gear: Acid 2.
I actually really loved Metal Gear Acid for the PSP, and then picked up Acid 2 because of how much time I dumped in the first one.
The story was horrible, the art style was like a mid-90s Marvel comic (Snake wore a leather jacket IIRC...), and the stupid shoehorned "3D" was such a waste of time.
And the Acid series was no more.
