This DLC may be set in the X4 universe, but it has nothing to do with the game. Disjointed missions with hordes of enemies that are almost impossible to master. Absolutely overwhelming for "inexperienced" pilots like me and it is incomprehensible why you should do THIS of all things before the main game after the not very explanatory tutorial. I´ve been replaying Mission 2+3 each more then 5 times to only get the "necesary" 3 star to complete them. I didn't even manage the fourth. Pure frustration, compairing to X1-3. My recommendation: if you don't have this from a bundle, don't buy it.
