How to unlock the We come in peace achievement in Arcade Paradise - Definitive Guide
For those who were wondering about this like me. I got it after passing 9 levels in UFO Assault. You do not have to do them all in one play. After destroying all buildings and completing the level that counts as 1 landing. Hope this helps those who were not sure on this.
