Ill give credit to @ZiT for his initial demon code, but i figured changing the value you'd be able to play as other demon forms (difference is it doesnt need pointer so mine are just heaps)

I don't remember this game much, but did you get the option to play as trish or that other woman (with the rocket launcher)?
Health code I had to put an activator because it seems to crash at end of mission (even @patjenova code did)
Is there any way to make these actually change your form and not just appearance?
