Do you mean the Ouro Flashback missions or the Ouro TFs ?
If you mean Flashback missions, there's a lot of them: only for the level 45-50 content, we're talking 79 missions in 8 story arcs...
... so you'll probably need to set up several sessions to go thru them all 
By the way, I'm setting up a Flashback Badges missions run next Saturday. I was not planning on doing it at the highest difficulty, but I could crank it up a bit if asked.

OH I mean the missions, yes I know it will take some time. Not looking to do all at one time, just take them one at a time.
So anyways, this is simply for those that enjoy pain. Lvl +4 baddies, set to lvl 8 team, though if I have a full team that won't matter. Not for badges, mostly for the pain. AV's are welcome as well.
I tried a 1 person set on 8 players with +4 baddies today and I was given my butt back to me.
So who is with me for the pain and the pain????
so with a team of 5 we attempted lvl 29 Ouro mission, one person dropped while Bama's computer decieded to bend him over. With the 3 of us remaining, we completed the story arc with only a minimal death ratio. All I got to show for it was a Red Recipe which was sold at aution for 500 influ.
I had a crazy idea, as I layed down at Reichsman's foot yesterday. I would very much like to run through all, yes all the Ouro missions, with a team of 8 at the highest difficulty.
So if you are interested in the type of sadomasochism let me know and we can work something out.
