There is a round container on Dantooine directly behind your ship
when you land that I cannot open I had a security level of 30 and still
would not open and I also tried every type of mine on it as well
and I also tried the security tunneler did anyone get this open if so
what's inside of it?
Average frag/sonic mines should work. Security seems to fail. Nothing dandy inside, random treasure. AFAIK, there's no über chest with fixed items in the game. They are all completely random.
With a high enough security skill nothing is impossible. Even when one says impossible, try equipping the infiltrator gloves and Exchange utility belt. It works for some reason.
Speaking of stubborn containers, anyone know the DC on the metal box in the queen's chambers (or what I call the queen's chambers) on Iziz? It's the north-western most room.
4 times through the game and I've only been able to open it once.
