Weapon of Choice

Weapon of Choice is an achievement in Halo: Spartan Assault. It is unlocked by scoring a kill with every handheld weapon in the game. The achievement is worth 5 Gamerscore on Xbox 360 and Windows systems, and 10 Gamerscore on Xbox One. It is represented by the game's "change weapons" icon. In the Windows version of the game, players do not need to purchase and use the Rocket Launcher, Spartan Laser, or (despite the achievement's description) the Sniper Rifle to unlock the achievement. In the Xbox 360, Xbox One, and Steam versions players must purchase and use all three.

If the player has already unlocked this achievement on another platform, it will unlock in the Xbox 360 version the first time the player uses one of the purchasable weapons. In the Xbox One version, players must use each and every weapon all over again.
