Ive got an idea that shouldn't be too hard to make. Take the campaign mission and let players to control enemy AI. I'll explain it on first FA mission as an example.
Start would be pretty much similar to what's there, but one player would have control of those 2 Order bases (or two players, each player having one base). Their target would be to kill the position you normally play in campaign.
The original player would start with some factories already, else it would be really hard for him. It would be diving straight into the action. Base would be pretty much the same as they are right now. I dont wanna do too many changes to that. ACU can start fully upgraded with T3, RAS whatever.
Now it will get bit more tricky to have fun during the next parts. Because depending on who wins this fight, I wouldn't want to end it here.
Anyway next thing is to defend the small city against 5 Order Bases. If the coalition player kills the order bases in first objective. Then the disadvantage for those 5 small Order bases could be really big. So I was thinking about restricting the area just to this fight. Coalition player wouldn't be able to use his main base. He would have control on the civilian base. (Some adjustments will have to happen here so he has a chance.) I ll think about this part a bit more.
Another part of the mission is to kill Order commander. Not much to say here. Each player having one base. Coalition player would get his base back as he had it in first objective if he survived. Else this part could be skipped and going directly for last objective.
Defending Fort Clarke against seraphim. Also pretty clear what will happen here. One player in control of Fort Clarke, second one Seraphim forces.
This could also take too much time so maybe it will be better to split it into different missions so if you wanna play just the last part you don't need to go through all the previous objectives. I ll try it out, how it goes.
So do you like the idea? Im open for suggestions how to do this, what you want to see there. And if this is succesfull I can try to do the same thing with other missions.
