Mission 13

Most of your weapons are disabled on this level until your weapons adjust. There is a large platform on the left side of the level that you can lure robots underneath and then remotely activate to crush them.

EMP pulses will occasionally disable robots. Use those chances to crush robots that didn't die from fall damage.

Secret weapons, turrets and the grenade can still be used while your weapons are disabled.

For an extra challenge, try clearing the entire level after you get your weapons back.
