[Bozos of Bones]

I never noticed vampires piss off warlocks. Strange.
Anyway, I've finally decided to change my question. It was X-Beyond the Frontier. Shame to all who played it and didn't get it. The new one:
You set up your strike force from your army for every mission. Your surviving troops gain exp, the ones that die are replaced after the mission with unexperienced ones. Stunning 3D graphics, excellent strategy and tactics and extreme playability.
