I'm tinkering with a fairly 'game changing' idea at the moment. It started with an idea and i'm looking through the rest of the film to see if it will work out right, So far it's looking good. I'll post details on that soon.
I can say right now that this idea wold include the removal of the entire helicopter scene, But if I do it right then the scene shouldn't be missed at all.
Right now I'm really looking at ways to bring some more DOOM flavour into DOOM.
