After the space battle, you'll transition to a zero-gravity boarding sequence. Use your thrusters (jump button) to move around and your grappling hook (aim button) to quickly pull yourself to cover or across gaps. Enemies in zero-G can come from any direction, so constantly check your surroundings. Aim for headshots, as body shots can send enemies spinning, making them harder to hit.
The environment is your friend here. Use debris and structural elements as cover. You can also use the grappling hook to pull yourself towards enemies for a quick melee takedown, or to quickly escape a dangerous situation. Be mindful of your oxygen supply, though it's generally not a critical concern in this mission. Clear each section of the destroyer methodically, ensuring all threats are neutralized before proceeding to the next objective marker. The mission concludes once the destroyer is secured.
