I managed to snatch defeat from the jaws of victory. After successfully assaulting two enemy bases with my respectable Tier 3 assault bot squads, I sat back to wait for my Galactic Colossus to finish in the sure knowledge that the other 2 factions would be a push over. Giant bomber flies over and manages to drop two bombs before being shot out of the air. Those bombs sadly landed on my commander.
Post crater I ramped up production of experimentals, finishing a Czar and a Fatboy due to a lucky converted engineer early on in the match. Sadly, while I managed to clear out one team, I never got a chance to properly assault the Cybran base and, through steady usage of Tier 3 bombers, they proceeded to level my base one large explosion at a time. The loss of my commander meant I was relying on energy storage buildings and since there's no Tier 2 or 3 versions of those you need a lot of rather weak storage buildings to make up the difference.
I was rather dubious whether "Forged Alliance" was worth getting since it seemed to only add one new faction, but there are a lot of smaller changes that really do make a difference, as well as a much more aggressive A.I. and no crashing.
"Supreme Commander: Forged Alliance".
