With S&Box introducing gigantic map sizes, proper realistic explosives could be a possibility. Not only that, but with my position in the queue, I could attempt to start development on GWarheads on the Source 2 engine. Now, this would come with a few issues. First off, I would require to learn C+, as well as S&Box's particle editor. Second off, this would all depend on the difficulty of how hard those tasks would be to carry out. Hell, I'm not actually sure when I'll be able to start development. This also depends on when S&Box receives workshop compatibility, and when its API is complete.

I will be adding to this thread later on. Stick around for updates.
