Awesmic
A tacked-on reskin of an older version of Hayate reimagined as a new playable character in the DOA series. Could possibly be working for Victor Donovan, or is Victor Donovan. Either way, Christie's sick of his shit, and that makes me happy.
Project Bokuho
Gameplay wise? Nothing but a Hayate clone.
