Edit: This is the achievement for beating the entire campaign or online vs. on hard.
Finished the last campaign I needed on hard last night to get this achievement with a friend. Anyone else done this yet? Did you do it through Campaign Vs. or Hard Mode? A ton of people? A few? Just curious.
Shipyard was a nightmare, but everything else went down the first run through. CC on offense/security took 2 run throughs, but was easier than I thought it would be.
GT: Nephaerius
On hard offline, no real challange after getting warm with bot behaviour. Shoot em as long as your team is here to hold it on their own.
According to steam 1,1% of the players got it. But these statistics shock me as only 86,5% have ever revived themselves…
This is the trophy for beating all mission on hard mode or in online versus, right?
I can’t be more than 1 or 2 missions away from completing this trophy, but hell if I know which ones I haven’t completed on hard. It’d be wicked awesome if, instead of just having white dots to tell you which missions you’ve completed, it showed bronze-silver-gold dots to tell you which missions you’ve completed on easy-normal-hard.
/sigh
I did everything on solo hard mode, Shipyard as security isn’t so bad if in the 2nd portion you play engineer and defend the bot operatives from the rooms adjacent the objective with your turret and mine(s).
Aquarium and Shipyard are tough, but I rolled with some guys last night and we did all of Security side, each in one try. Good times.
Based on the flavor of this thread and my personal experience I’m sensing a need for an Insane difficulty or something along those lines. Something that will make me break controllers and and TVs out of rage 
versus was quite easy, killn noobs all the way? i think so 
I did it by playing the campaign on versus. Besides the occasional frustrating hacking objective i found it to be not that hard. (Played mostly with/against bots.)
Edit:
I hate the last objective on the resistance side in “Resort”. I HATE IT!
Did it on hard with bots. Was pretty easy when you got the hang of their tactics and routes. All maps except shipyard took 1 try.
Campaign > Hard for me. As long as you have a few people on your side it’s a breeze. Except that damn missile map as security >.<
But eventually got it done
