I'm amazed that someone actually remembers Alien Breed 3D, let alone trying to remake it. I played it a lot back in the Amiga days. I could never get that far in it, although I've since finished it thanks to the convenience of emulator save-states.
It seems like not a lot of progress is being made on this though, which is unfortunate. It is a pretty ambitious project, and although the cynical part of my brain says it isn't going to happen, I'm still going to hope this gets somewhere because I would REALLY like to see it.
I don't really have much time on my hands to help you guys at the moment but you have my support, for what it's worth. Perhaps give me a shout later on down the line and I'll see if I can knock up a website for you guys.
