Do you keep losing Cpt. Medison or is the mission goal unclear to you? It was one of the harder nuts during beta too. I'll make all Easy campaign missions slightly easier in the next patch. Here's a spoiler: Spoiler If your problem is the mission goal, remember that you are supposed to land troops from your colonization ships on the space station. The location of the space station is marked by a blinking beep on the minimap. Once you have done that, the troops will allow Cpt. Medison to escape in an enemy heavy missile frigate. It has a small medison portrait near the ship and is highlighted on the minimap, too. Bring that ship back to your jumpgate so she can escape. If your problem is that you keep dying or losing her ship, then I recommend trying something different. Best way is to take out the left planet, that way the enemy has it harder to reinforce on the left side of the map giving you way more room to breath. In any case, don't try to take on the enemy's main fleet. This will only get you killed.
