Assault Ops



Assault Ops, also known as Challenges in the Windows versions of Halo: Spartan Assault, are a optional challenges featured in Halo: Spartan Assault and Halo: Spartan Strike, which can be undertaken in order to earn currency to spend in the game's Armory. Assault Ops typically require the player to kill some number of a specific type of enemy, using a particular weapon, vehicle or grenade. In addition to each of three mission-specific Assault Ops per level, a rotating selection of three weekly Assault Ops was previously available, which could be completed on any mission. However, these have since been discontinued.

Three achievements are tied to Assault Ops; Extra Credit and Thorough can be earned by completing all of the mission-specific Assault Ops in Halo: Spartan Assault and Halo: Spartan Strike respectively. The third achievement, A for Effort, can be attained in the Windows version of Spartan Assault by completing all of the Assault Ops for Operation F: Hydra.

In both Spartan Assault and Spartan Strike, progess in the game is shared across all versions of the game on Microsoft platforms, and as well as between iPhone and iPad (although not between the Microsoft and Apple platforms). As a result, progress towards Assaults Ops carries over between these platforms. The Steam versions of the games do not include this feature.
