Just finished mission 12 - it was extreamly difficult. They keep on sending Battlecruisers and Destroyers.
My advice is to max out your fleet and put ion cannon platform and ion frigates in your building que to keep on producing them as they are destroyed.
Keep your fleet together and concentrate your attack on one ship at a time.
First destroy the destroyers and then concentrate on the battlecruisers.
There are 2 shipyards and 1 carrier, take them out asap, it gets easyer after that.
The station can also produce Battlecruisers and destroyers, but not as fast.
Don't worry about the objectives, there is enough time to do them.
Very imporant:
Before doing the last objective rebuild your fleet, you are going to need it in the next mission.
Make sure you've got a lot of ru's.
