First I've done a light search for this topic and I have found none but If there is I am sorry a little tough to navigate around on this site to those who arent use to it.
Now I'm mostly leaning towards Echo's downloadable map's trophies that I would like to collect but its become a bit troublesome considering not everyone has downed the map's or people with them just arent on so I thought I'd try to set up a gathering of the sort cause I'm sure other's are having a hard time as well.
So here are the trophies I'd like to grab:
in EX pack 1: BURNING INSIDE takes place in FOUNDRY.
in EX pack 2: ROCKET SOCKET only place I've found a rocket launcher is FOUNDRY.
DELIVERY SPECIALIST WHY NOT FOUNDRY
Even If I were to get these I would still help others with these or any other trophy to the best of my ability. Now I'm not able to get s or s+ rank but if I had to give a tip I would say use Specter cause he can spot all sorts of items like data collection (just not the camera's) that should help you in that area.
