I've installed the Thargoid addon for much more fun...and I must admit that I like the look of those additional ships VERY much. I've also the Navy Addon installed...so I don't really know which one is the cause of the stuff I observed.
1) I believe that the Thargoid frigates should be much more tougher. I can kill three before my laser overheats?!?
2) The bounty for those Thargoids is pretty strange. Warships/Invaders and Frigates often give far less of a bounty than a Thargon (Thargoid robot fighter). When doing a navy mission against them, the bounty for robot fighters often rises from 50 to 114 credits, and even the "minimal" amount typically is higher than the resale value of scooped up Thargons.
3) Inactive Thargons still count as a kill and give full bounty, while not posing any threat at all. Should it really be that way? When doing a navy mission against them, it's pretty heavy income to clean up around the big navy ships that do not leave...and then move on into the big "cloud" of inactive fighters until the scanner says "condition green"....check the kills and money, fire an energy bomb, check it again and SMILE...that's very easy money and repays for the kills lost due to a crashed game. Should it really be that way?
4) I don't know if it was a bug or me being to fast at the keyboard, but I had sometimes the message that I was hiding while Thargoids attempted to raid the station...but in no occasion I saw a "please launch" message before. Maybe I hit the keys too fast before the text was displayed? If it wasn't a bug causing that message, it could be helpful to make the fight instead of flight the default button.
Uhm....and and I like their humour....icebergs for soap, volcano grilled burgers....but when I visited a bar after such a big battle, I had some "erotic edible insect lapdance"....and thought of the famous last words "Guard your mating traditions, human ..." - is there any chance that those edible insects were Thargoids? That would explain pretty much...especially since humans do eat sentient life forms if they taste good
