Hello, just wanted to share something. I don't know if it still works (worked a few weeks ago) but you can remove everything from the first konfiguration and go full lasers on the second one.
Click on TA while your ship is empty and join the arena as always.
If you're in the arena, switch konfiguration.
You now only have 1 Konfiguration you can shoot with, but in most cases your opponents won't have anything either, so it's always free 500 Uri + another price.
Regards
