Personally I'd like to see a campaign thats more unique than multiplayer/skirmish, such as a mission designed around the weather mechanic, as an example you could be put on a map where the weather controller has been sabotaged or malfunctioned causing even more extreme weather than what you would normally see, this could effect your units even more so, there could be safe regions or areas on the map to capture that give protection against the elements, this could be a timed thing such as every 5 minutes the weather becomes extreme and you must get your units outside of its influence or lose them, im sure you get the point.
I also believe a unique system like with StarCraft 2 the heart of the swarm where you have the ability to select upgrades for units, this could range from stat buffs from more health or faster build times to units you normally wouldn't have access too, or special abilities you can use, like for example an orbital strike, something that allows you to carry over progression through your entire playthrough of the game.
I personally believe the campaign should be heavily focused on the story, SupCom's story was overshadowed by its gameplay in my opinion there was story but you would normally just ignore it in favor of just completing the mission and moving on to the next, I'd like to actually be invested in the story and caring about the characters and what happens to them. Since i am on the topic of story i suggest having the campaign similar to the second game where each faction has their own separate story leading to their separate outcomes or consequences, allowing players to pick their own outcomes could also lead to a more invested story where instead of following the dialogue you are actively participating in whats going on and having to face the consequences of your actions whether that be immediate or down the line, i dont entirely know how this will work for co-op but i'd imagine the host picks and the second player either gets no choice or can just vote while leaving the decision ultimately to the host.
I will say that i am not a developer so i don't know how well any of these suggestions would fair inside the game but i personally believe sticking away from just plain skirmish battles like "Hey commander, you've spawned at this place, kill that other commander" and instead be more story focused, with ofc killing commanders but not that being the end goal for every single mission, variety will make it refreshing and not feel like you're playing skirmish with people talking in the background.
I'm excited to see what you guys come up with when the kickstarter reaches its campaign stretch mark
