EVERSPACE 2

and this achievement can both be gotten in phase 2 ( phase 1 is the destruction of the launch bays) of the first dreadnought mission. Set the difficulty to very easy if you are afraid of failing it and dont have a save thats right before starting the mission and this will be a walk in the park. Just shoot everything that gets close to the spaceship you are tasked to protect while it hacks the engines. There arent many fighters to begin with and this will be over in about a minute. Once the Dreadnought bails on you both achievements will unlock.
