GATM

This is a proof of concept.

Use your cursor to click on the mob fabricator to bring up a "hack menu". Click any button to disable/destroy the fabricator. Your cursor can also "fry" enemies by clicking on them. Your dude fires missiles periodically. 

The mobs will reduce your HP. The orbs will reduce your hack energy. Having the menu open will reduce your hack energy. To get more energy, hover your cursor above your dude.
