Tour of Duty

Tour of Duty is an achievement in Halo: Spartan Assault for Windows. It was released on August 29, 2013 as part of the title update, Operation Hydra, along with four other achievements. It is awarded when the player earns all gold stars in Operation F: Hydra. The achievement is worth 10 Gamerpoints. It is represented by a circle with an "F" inside a pentagon with five stars surrounding it.

The Xbox One and Xbox 360 versions of Spartan Assault - released December 23, 2013 and January 31, 2014, respectively - do not include the Tour of Duty achievement. Instead, earning gold stars in all Operation F missions is required to unlock the 117 achievement. The Gamerscore from Tour of Duty is added to 117.
