After you defeat Drall the First in the void, you unlock the first of the elite version of co-op levels. Warmage Academy. Once you've defeated the elite version of Warmage, it will send you through the rest of the co-op levels as elite versions in order. Finally you will have a mission to defeat Drall again in the eternal battle. You will have to go through a whole bunch of waves to get to him. I've heard that it might not recognize doing the completing the elite version if you do it in multiplayer.
