Safety Not Guaranteed

Safety Not Guaranteed is an achievement in Halo: The Master Chief Collection. This achievement is obtained by completing one of the two Halo 3: ODST LASO Campaign playlists, "LASO Non Stop Action" or "SLASO Campaign".


The achievement's name is in reference to a famous personal ad asking for a volunteer to time travel with them, warning them "Safety not guaranteed."
