Get Lost.
To complete this achievement, you must "get lost" in the third "Heist" Mission.
To "get lost", you must pull your system away from the path of stars being fired at you. As soon as you start the mission, alarms will sound as stars are fired at you. Immediately move up or down to escape the path of stars.
When you get lost, you still win the mission, but it has its own success text.
You've evaded them, I guess, but now we're totally lost...
