I'd love to see a remake of the map 'totalwar'.
For those who don't remember, it was a axis vs commies themed map (including theme song when a flag was captured). It featured an outdoor area with a huge wall in the middle which contained 2 sniper nests. I believe there was also a 'nuke' button in these sniper nests to wipe out everything moving on the enemy yard.
It was actually quite a drag to play this map since the only path towards the flag was a very narrow spiral/corridor, but I'd love to see it again on servers for nostalgic reasons
