Titanfall is a multiplayer first-person shooter video game developed by Respawn Entertainment and published by Electronic Arts. It was released for Xbox One on March 11, 2014. The game was anticipated as the debut title from developers formerly behind the Call of Duty franchise.

In Titanfall, players control "Pilots" and their mech-style Titans, and fight in six-on-six matches set in the war-torn outer space colonies of the Frontier. The game is optimized for fast-paced, continual action, aided by wall-running abilities and populations of computer-controlled soldiers. Up to 50 characters can be active in a single game, and non-player activity is offloaded to Microsoft's cloud computing services to optimize local graphical performance. The game's development team began work on the title in 2011, and their Titan concept grew from a human-sized suit into a battle tank exoskeleton. The team sought to bring "scale, verticality, and story" to its multiplayer genre through elements traditionally reserved for single-player campaigns. The 65-person project took inspiration from Blade Runner, Star Wars, Abrams Battle Tank, and Masamune Shirow of Ghost in the Shell.
