A for Effort

A for Effort is an achievement in Halo: Spartan Assault for Windows. It was released on August 29, 2013 as part of the Operation F: Hydra title update, along with four other achievements. It is awarded when the player completes all Operation F mission challenges. The achievement is worth 5 Gamerscore. It is represented by a circle with a check mark inside it.[1]

The Xbox One and Xbox 360 versions of Spartan Assault - released December 23, 2013 and January 31, 2014, respectively - do not include the A for Effort achievement. Instead, the Operation F challenges must be completed to unlock the Extra Credit achievement, which requires the player to complete all 90 of the game's mission specific challenges, now known as "Assault Ops". The Gamerscore from A for Effort is added to Extra Credit.
