Arena help please

[Jt Little]

Dykuso. Arkfall, and Ridgecrest arenas I can't get gold to finish Golden Badge. Tried different approaches but there just aren't enough things to kill. Doing em solo. Have to be missing something. Any help gratefully appreciated!

thx

Dykuso..
The only way i beat this was by killing everything hella fast.
When the enemies spawn round you Kill em as fast as you can.
Need 4 people about 5900+ with strong mass cannons
