Kill a number (forget how many) of enemis with a count down time. (3 wave) they don't spawn all in the same time, so ultimate skill isn't very effective.

Tesla of vauban is very effective (trow some in the center and just waiting), more than dethcube i've see (i've see enemie die by tesla , but i've don't see my cube shoot , maybe cuz my tesla kill them before).
