No, not the horde-based twin stick only one stick sort of shooter. That’s Vampire Survivors, even though I keep getting the two names mixed up. No, this is the Capcom 1-on-1 fighting game from the late 90s heyday of Capcom 1-on-1 fighting games. There was a cheap bundle of bundles (a bundle^2, if you like) on the eShop recently where you could get Street Fighter 30th Anniversary Collection and Capcom Fighting Collection together for less money than either collection had ever been on sale for individually. Ah, gwan then.
Vampire Savior (the lack of a U is making me queasy), or Darkstalkers 3, depending on region, is a CPS2 based game, much like Street Fighter Alpha and X-Men: Children of the Atom, so it has big ol’ sprites and loads of animation. The fighters are generally based on monsters like a mummy, a vampire, and a Definitely Not Frankenstein’s Monster.
I played as newcomer-to-the-series Baby Bonnie Hood, who absolutely isn’t supposed to be Little Red Riding Hood, and has a machine gun and a dog. It was silly fun.
