You can finish this level without using the Replicator (easy as well). First priority for this was to create several Rocket Towers around the NW platue. I also tucked 3 cyclops to the right of the rocket towers, nearer the other replicator pad. I locked the cyclops into that area by placing generators to the rear of the rocket pads. OMNI units couldn't touch my area between the cyclops and the rocket pads, no mix could get close. I continued to develop my area and extend to the SW with my Galaxilite processors. Developed HRC and created several corporate raiders.

place corporated raiders behind small tree on west side just infont of OMNI complex. They never got touched.
Created a MASSIVE army of Hydra's, rocket troopers, and Liberators to destory the towers and security at the OMNI entrance. With the OMNI forces occupied with my army, I snuck the raiders in and started confiscating all of their storage, power and other buildings. All glory was called then. Systematically destroyed the rest of the forces. Just for fun I then replicated several Bullpups and continued to mine all remaining Galaxilite from the mission screen.
