You will receive the achievement after you get out of the alien ship

Story achievement

Episode 07 - CENTER
When gravity turns off, always fly towards the light.
Having destroyed the first yellow glass flask, this will be a hint for further actions in the large hall, where you will have to destroy 5-6 of these glass flasks in order to fly further in the center of the hall.
When attacking aliens, the easiest way is to grab them with your hands.
Where there are transparent walls, just wait until these walls disappear and fly on.
After the high-speed tunnel, in the large hall with the “brain”, fly right up to the glass wall.
Then in the opposite direction to the round gate.
After the first large round gate, there will be another similar gate. Just wait near the gate in stealth mode. I was hiding directly in front of the gate behind a black ring, along the perimeter of the circle.
After 2-3 minutes the gate will open and so will the achievement.
