Add some solo missions where we can play with the Recon Rangers or the Scarlet Scouts. Yes I know this is a co-op game but every co-op game has at least some solo aspects in it as well. I suggest it to be a series of some weekly prestige missions that alternate, where you play without your pet or shield, but given a the uniform of your respective team (either the Recon Rangers or the Scarlet Scouts) alone with a temporary shield (like in lockdown) and your weapons of choice, these missions will have one of two "modes":

(Recon Rangers): Where you play as a Recon Ranger and go help a squad or retrieve an artifact while being stealthy or other stuff that Recon Rangers do.

(Scarlet Scouts): Kinda like a regular clockworks run though more challenging and you have to kill everything in that area or kill a specific boss or monster (could be The Collector or a new boss type that's kinda like an armored gremlin or a tank) or other stuff that Scarlet Scouts do.
