Teenage Mutant Ninja Turtles Mutants in Manhattan

I tried a bunch of options, watched different videos. There is only one solution. Launch the first mission solo on easy. The task will start immediately. Climb higher on the building and knock down all the enemies. Stand at the very top and wait for the next mission. Order the turtles to wait. When the mission appears, do nothing, just stand there. In 5-7 minutes, you will automatically be transferred to the beginning of the next test. Go through again and it is desirable to be at the top again and for the rest of the turtles to be nearby. Again, order them to wait and wait for the transfer to the third test. 4-5 tests and there will be a boss. Kill the boss and get the trophy. It is important not to kill anyone outside of the tests and that no one notices you.
