Futuristic Update similar to the WW2 update
A cool thing to see in this game would be a completely new update that's centered around the future, Kind of like Battlefield 2142. Since they already did WW2 this would be a great idea to add as another option for new gamemodes and a new setting.
Even better is the weapons can have some imagination and have some even be completely fictional.
Maps could probably utilize new mechanics as well. There could even be new vehicles that are based around the future setting. And I know It does sound like a lot, But it would be something completely new for Pavlov.
