During campaign mode are things different. You should reach X-3043 later during campaign, try reach it earlier may lead to many different problems including that you will be unable continue in campaign. Please read starter guide in wiki and look on our video guides how to use 'rapid fire' .. this with low firerate guns with high damage will kill low npcs very fast with some practice.
In the Campaign u reach X-3043 in the beginning (after ~20mins, first u had to fly to Reihnland).
Means i was already there in the normal campaign way.
Its interesting but its cant be a must to use it, for playing the crossfire Story.
I destroyed 5% hull dmg before they reload there shield, guess anyway i need a new ship/wepaons.
