I'm flying around in Liberty space right now doing the campaign and I'm really impressed with all the new ships. Last time I played was 1.4 or something like that. I got a Swashbuckler first and slapped Flashpoint turrets and Vengeance guns on it. Needless to say it obliterates all early mission enemies and bandits. Sure, it turns slowly but it's easy to preempt the AI flightpath...also it's got decent speed for a freighter. I do missions and always load up my cargo bay, raking in profits on the move.
Now I spent some time looking through the wiki for ships but it's all a bit much. Could you give me some good pointers on how to progress ship-wise throughout the campaign? I prefer lots of guns with high power output.
