SPOILERS!
Did anyone beat this on Normal or higher?
I was rocking along, kickin bootay on all the usual suspects (Drengin, Yor), when this big red space squid shows up and drops 10 alien buttkickers on my planet. I drove them off, but they killed thousands! It was only after that I decided I'd better get moving, but too late. By the time I built some transports, a few heavy fighters and a couple of constructors (for starbases to extend my reach) there were squidleys all over the place!
Rather than suffer the pain I surrendered to my ally, the Altarans. I figured I'd rather lose gracefully than face death by seafood. Anyway, looks like we have to show the Torians some love now.
If someone has a winning strategy for Siege, please post it here!
