I would love to see dual objective maps introduced to Dirty Bomb. For those who don’t know these type of maps: both sides have an objective to defend and one to attack. The winner is the one who successfully attacks their opponent’s objective.
RTCW had a lot of these style of maps, including two that came with the game–mp_depot, mp_destruction. W:ET’s campaign mode was more popular than stopwatch or objective mode so not a lot them were made for that game. But there were a few popular ones-- byzantine and baserace come to mind.
The best part is they do not have to be large maps or require more than one spawn point. A community made map mp_bridge for RTCW is a good example of that
Hell even Splash Damage cut their teeth working for ID with a dual objective map MP_marketgarden (my all time favorite map). Now that is a map I think would work well in Dirty Bomb. I would love to see a remake of that map but placed in London obviously.
