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 Gamerpoints on Xbox 360 and Windows systems, and 10 Gamerpoints 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 and Xbox One versions players must purchase and use all three.
