I just started playing for a few days. I read that i should keep an eye on some grindy challenges.
I learned that for rocket launcher, i should get to level 5 of 'collateral damage' challenge (200 kills with splash dmg) to unlock another undiscovered challenge. But i don't have that challenge listed. There are only 3 challenges listed under rocket launcher. (Undiscovered, magic missile, and get a rocket up ya).
I just started the 'lets build a robot army story mission. Will that 'collateral damage' challenge appear later on? Or is there smth i have to do to make it appear?
EDIT : Nvm. Played around with my rocket launcher, and it appears, along with 2 others (total 6 challenges). I think they popped once i get 10 rocket kills (completed level 1 of 'get a rocket up ya' challenge)
