Immediately apologize, but I write through the translator.
hello
once again I can not pass TPG Test Certification Part -3
Several times interrupted the mission, so there is no way to start a new one.
If there are certain rules of passage, please.
Destroy all enemies in the two sectors, then wait and nothing happens. Inscription " Kill then all" and hanging.

It's hard to say without seeing exactly what you are experiencing.

After clearing the two sectors of bots, you should be given a nav route back to the station where you accepted the mission. Does the nav route appear for you? Are you sure you destroyed all hostile bots in the second sector? (There should be 20 total).

That's right, destroy all. in the two sectors. after waiting for about 30 minutes, so it was already 5 times.
Maybe it's because I'm out 2-3 times with the sector to replenish their ammunition and repair? Although the wiki says it's possible.

drop a piece of cargo when you enter sector, stay by it during the fights. Then, when you jump out, you can jump back in and the bots will still be roughly center to where you started. Alternatively, use pure energy, and try to do it without needing to leave sector.

Advice please. What is - pure energy?

Energy is the bar you have on the right side of your HUD; it gets depleted by using turbo and certain weapons.

Savet was referring to using only weaponry that consumes only energy: no ammo. You can find more info on weaponry here:
