For new players, the way to rank up fast on creep rock city and how to get the xp and credits for gear when players aren't around for MP. If you have difficulty pulling off fast rank 4 against the insane ai try it on hard instead, still very good credits:time
After a profile reset you should do this a few times to open some nice crates and get past profile level 1, makes a huge difference. Enjoy it while it lasts, one day the AI will be good enough to back up the insane servo teams it rolls with
