So a friend of mine and I were talking about how brutal doom pretty much made doom 1 and 2 even more amazing. essentially this led to a question of making a new game like so. After our nostalgia trips we began to think on such and due to my lack of keeping up with unity in my time away I have no clue how it would work with the new UI options. and 2d interface. Like in brutal doom I know you got headshots. I know in the 2d engine you can set colliders for such but how could you do that in the 3d engine using planes. I also don't know if the creation of sprites for enemies is the same, Going to be honest here. don't know how that was done in older versions either. as for AI and finishing moves wouldn't know how to program that in either. Its been to long. Some pointers in the right direction would be great.
