Gods Must Be Strong

Gods Must Be Strong is a Campaign Achievement in Halo: Reach and Halo: The Master Chief Collection. This achievement is awarded when a player completes every campaign mission in Halo: Reach on Legendary.

Trivia

 * The achievement's name is a reference to a quote by the Prophet of Truth, when addressing Avery Johnson in the Citadel; "You were weak, and gods must be strong."
 * While this Achievement is awarded for completing Campaign mode, completing each mission in Campaign mode alone (solo) will unlock the A Monument to All Your Sins Achievement.
