Mission 17

This level has a factory which will occasionally spawn swarms of mini-drones. It will show plumes of smoke from the three areas they will emerge right before they come out. This factory is located at the top of the level and must be destroyed quickly before you are overwhelmed.

You can set the blaster turret on the ground below the factory to constantly fire at it.

The 'Infinite' Jump Cannon is also useful to setup multiple strong hits against the factory.

If you get overwhelmed with mini-drones then the Super EMP will destroy all of them.

Be careful not to destroy all the spawners and the Gate before you destroy the factory. An Overlord will spawn and then you'll have to deal with both the Overlord and the swarms of mini-drones at the same time.

To defeat the level you must destroy the mainframe, the mini-drone factory and the trap drone generator.
