How do you complete the just do it achievement on insectonator zombie mode?

to commit suicide use lightning on nuke,bullseye, you throw a dart in the middle of a boom scenario selectioner to get the dart, the armageddon you throw napalm or exploding stuff into the nuke, and to get zombie ball, you have to get the ball by scoring 5000 points in one level, and if you wanna do that, then just keep on playing annihilator, and the final step, get 21 fast kills using the ball. Lastly, for fly anvil fly, just throw the nuke, then chuck (or throw) an anvil on it.
