Waterworks! That map could be so epic remastered!
I would keep much of the map the same like lockout and just add new subtle changes like additional paths, greater stalactite drops, maybe add a large beautiful underground waterfall and larger bases with additional vehicles like the new gun goose etc. Of course all in keeping the map balanced too though! I just see so much potential for an epic remake here that could be very visually beautiful and very large and fun to play in BTB!
