Upgrade the engineer to lvl 3
Place down a lvl 0 g mini
Place down a lvl 3 dj
Upgrade the g mini to lvl 2
Upgrade the g pyro to lvl 3
Place down another lvl 2 g mini
Place down 2 more lvl 2 g minis
Upgrade a g mini to lvl 3 (To apparently kill the lead enemies)
Place down 3 lvl 2 commanders and chain
Upgrade another g mini to lvl 3
Upgrade one of the g minis to lvl 4
Max the g pyro
Max the DJ
Max another g mini
Upgrade the engineer to max
Max a commander
Spam max engineers, and once those are maxed out spam max g minis.
