Thanks. If I had the time, patience and available sprite work I wish I could create my own AvP project someday. What I'd envision is you initially have a small roster of a Marine (Grunt sprite from Capcom's AvP), Predator Warrior and Warrior Alien. On completion you begin to unlock other characters until eventually the Alien Queen as a final unlock. AI partner coop would also be a must have for this kind of side scrolling beat em up.
I think I just played way too much of the AvP Mugen release by Ristar87 & Sergeus and wished this could also of been an OpenBOR project.
