This is done by taking part and completing a challenge on the ships console.
When the game loads you inside the ship randomly upon death walk forward from the cockpit and on your left is the exit to the game. Between the cockpit door and the hole is a console with the challenge.
Launch Challenge
This is to survive as long as you can whilst making your way to the desert.
Kills earn you a lot of points, but you should also pick everything up on your way through the level to get a bigger score.
I managed to get 1.3mil points on my first attempt so it isn't that difficult.
