Battle Royale Mod?
Again, I can't program or anything, but it would be cool to make a battle royale mod (based on the novel/manga) deathmatch where everyone gets released into the arena like 10 seconds at a time, when you die your dead and you get a random weapon. It would also be cool to have areas become forbidden like in the book, where you die if you enter them. A total conversion with realistic weapons and japanese school children models would be cool too.
Really love the manga, seems kinda hard to make a fun fps out of it tho. Still if its done right u could make something out of it.
I loved that film. wouldn't mind seeing a mod
