    Go to Navigation (front of the ship) and select Earth. Scroll around to the golden coloured tab labelled Gift From The Lotus and start a game. You will have to defend the cargo from 20 waves of enemies. These enemies can be tough, so make sure you have a good group of players. After the 20th wave, the mission will complete and you will earn this challenge.

    ** You do not actually need to play through all 20 waves in order to complete this challenge. I joined a mission during wave 12 and still unlocked the challenge after the 20th wave.

    You will also earn the Ride the Wave achievement if you haven't already done so.
