ROUND 4
If you focus on trying to save Freeman, invest all your resources into restoring his mind and, hopefully, a physical form. Sacrifice an Energy Pod (if you have one) and then replace Freeman (Standard Algorithms) with a Freeman AI (Experimental Algorithms) and then battle a Rival Commander for your Final Battle.
OR
Do you choose to invest all your resources into rebuilding your Tech systems? If so, sacrifice Freeman AI (and an Energy Pod if you have one). Gain a Lost Fleet and then battle a Rival Commander for your Final Battle.
