Why? Because it looks awesome.
It's called the F-150 Halo Sandcat, and Ford has built only one. Set to have its official debut at the Electronic Entertainment Expo (E3), the F-150 Halo Sandcat is being used to promote the release of Halo 5: Guardians for Xbox One as part of a joint effort between Ford, Xbox, 343 Industries and Galpin Auto Sports. The styling was inspired by Halo's United Nations Space Command vehicle, but it's still based on the 2015 F-150 Lariant SuperCrew 4x4. Power comes from a 3.5-liter EcoBoost V6 and equipped with the FX4 off-road package.
Further modifications include the Addictive Desert Designs' Baja XTR off-road conversion kit which features custom FOX Racing shocks, Deaver leaf Springs, a Currie full floater rear axle, ADD fenders, side steps, a chase rack, and 17-inch wheels with off-road tires. The interior, not surprisingly, comes with an Xbox One custom gaming system with displays mounted in the rear head restraints. Will Ford build it for production? Very likely not.
