HALO 5 MERCENARIES MODE

Hey guys!
Do you know about Resident Evil Mercenaries Mode? It’s basically like Halo’s firefight, kill enemies and take rounds, but you can choose differents characters.
So imagine:
It would be exactly like Firefigh mode, but with the possibility to select differents characters like:
Master Chief
Locke
Arbiter
Jul Mdama
Fred
Kelly
Linda
Macer (?)
Buck (?)
Romeo (?)
Didact !
Tartarus
Johnson
And who knows? Maybe Noble 6 just for play as him! (I know he’s dead)
Each character of course would have differents abilities and weapons
Would you like it?
