Titanfall 2 is a first-person shooter video game, developed by Respawn Entertainment and published by Electronic Arts. A sequel to 2014's Titanfall, the game was released worldwide on October 28, 2016, for PlayStation 4, Windows, and Xbox One. In Titanfall 2, players control Titans, mecha-style exoskeletons and their pilots, who are agile and equipped with a variety of skills ranging from wall-running to cloaking. Set in a science fiction universe, the single-player campaign follows the story of Jack Cooper, a rifleman from the Frontier Militia, who bonds with his mentor's Titan BT-7274 after his mentor, Tai Lastimosa, is killed in action. Together, they embark on a quest to stop the Interstellar Manufacturing Corporation (IMC) from using a superweapon to destroy the Militia base on the planet Harmony.

In science fiction, mecha or mechs are giant robots or machines typically depicted as piloted and as humanoid walking vehicles. The term was first used in Japanese after shortening the English loanword 'mechanism' or 'mechanical' , but the meaning in Japanese is more inclusive, and 'robot' or 'giant robot' is the narrower term.
