I was playing the campaign over again on veteran and on the level where you play as Rousseau and get the suitcase from oberst fischer I was thinking it would be cool if they turned that map into a gamemode on multiplayer where the allies have to rescue oberst fischer in a certain amount of time before the germans execute him, as the allies you would have to reach him untie him and make sure he don't get captured he also wouldn't be able to get hurt and escort him too the extraction zone then wait for the reinforcements to arive. As the germans you would have to defend oberst fischer from escaping he don't move if your by him you would tie him up each time the allies untie him and you get him back. There would be a time limit obviously and maybe for a twist the allies would have 7 players instead of 6 and the 7th would be oberst fischer and could only move when untied and being escorted but could not fight or get hurt. And maybe for the germans a 7th player as well would be the german that had him at gunpoint in the campaign level and you would defend him but you could die and when fischer was untied and being escorted you won't respawn untill he's tied up.
The defenders will camp their asses off. Especially when it will be in a building.
For the Fischer guy it will be boring
Ask a co-op mission will work
