This is mission 2 of the Galaxy on Fire 2 walkthrough.
When Keith docks, Gunant Breh tells him to fill his inventory with another hold full of ore. The mission proceeds like the last one, but a pirate appears in the end of the mission and chases him back to the station. Since he is not yet supplied weapons, the only option is to retreat.
Tips and Tricks
Just play the mission like the other, after the pirates appear you have more than enough time to make it back, even playing on extreme. It is the tutorial after all.
It is also the only mission to achieve the Survivor Medal on relatively easy conditions since this is the only time you can accurately calculate when to enter the space station without being blown to pieces or having the progress stopped.
