Guys try this in zeta

[abdulmecit1997]

I saw somewhere but i didnt believe it, maybe luck or its really working idk but im 10 havoc finally.

Last wave on zeta, kill all the npcs except devourer. Go up-left corner in radiation zone and kill devourer in there. Stay in radiation zone till rewards shown.

I know it makes no sense maybe pure luck but maybe, just maybe..

It's luck based, no secret formulas to it.
