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.
Humanity lives in the deepest reaches of explored space in a vast region known as The Frontier.
It contains many well-known and inhabited star systems, but many more worlds remain uncharted.
Most people will never travel this far away from normal civilization, but for pioneers, explorers, mercenaries, outlaws, and soldiers, the Frontier offers both adventure and opportunity.
Major interplanetary corporations known as Hammond Robotics—a major manufacturing, aerospace and defense contractor—used resources of the Frontier to make builds of mecha-combatants such as Titans and Spectres.
In Titanfall, players control "pilots" and their mech-style Titans, and fight in six-on-six matches set in war-torn outer space colonies.
In Attrition, a traditional Team Deathmatch, teams compete for the greatest kill count, and bot kills and Titan kills are counted.
Pilot Hunter is similar to Attrition, but only counts pilot kills.
The latter locks onto multiple targets before firing multiple shots in a burst.
Players generally require three Smart Pistol shots to die.
