I been doing the loot allocation mission as well as hyenas missions for days now but I can’t get the mercelles, does someone knows any method to increase the chances or Im just out of luck
AFAIK theres no sure method. Probably the best thing to do is just killing Hyena bosses. Repeat Hyena missions on Hard/challenging for more drops. Try Jefferson Trade Center and Bank HQ missions and just grind them mercilessly.
