The Final Operation(s)

Whenever they do a FINAL operation for this game, it should be a level about the deaths of Acheran & Chairon. I got a couple ideas for this.

1.a) You progress through a level as normal, the final part of the level is you holding off an attack with Chairon & Acheran for a time limit. Once that time limit is reached, you're now just holding out until all the players are dead. Reaching an end to the Operations Marines alongside Chairon & Acheran.

1.b) Pretty much the same as before, but this will also be the sole level in Operations to feature 6-player co-op where both squads have to link up to Acheran & Chairon from different directions, but foe the final fight you all fight together and die together.

2.) Possible follow up mission to 1.a, or just its own but you play as a the group that went in to recover their bodies. Could be the other squad since only one group died?

I just want something that give some better closure to their characters, gives them a proper hurrah and by the developers who made them to begin with.

At the very least we should get a book.
