The mystery Utopia Battle Star of the seventh seven day stretch of Season 9 can be discovered only outside of the Pressure Plant.
To really make the battlestar show up, you should initially finish a the full arrangement of week after week challenges.
When any five arrangements of them have been finished, this Secret Battle Star can be gathered and the test “Locate the Secret Battlestar in Loading Screen #7” will show up in the Utopia Challenges. It will compensate you with one full fight pass level.
Go to the spring of gushing lava, Pressure Plant. Where the magma comes up short on the well of lava you need to go up the steel stairs. The careful area you find in the video.
