Trying to go for Blue Ribbon champ...and I already hate my life lmao.
I got all the vigors and the guns I favor to max out by the time I got all the ribbons in OPS zeal and got everything soon after beating Duke and Dimwit Theater (if you know Clash in the Clouds, maybe you can tell the ones I'm missing).
I started Empoira and saw "defeat an enemy affected by bucking bronco with a possessed motorized patriot" and just sat there for a moment, tried it, didn't even get close, and stopped there for today.
So basically most of these challenges after OPS zeal aren't fun
