Players fight either on foot as free-running "pilots" or inside agile mech-style walkers called "Titans" to complete team-based objectives. The game is multiplayer-only, but injects single-player elements such as plot, character chatter, and non-player characters into its matches. Set in the near future on a distant frontier torn apart by war, Titanfall drops players in the middle of a conflict between the Interstellar Manufacturing Corporation (IMC) and the Militia. The action is rapid and varied featuring parkour-style wall running, massive double jumps and the ability to hijack titans. The freedom to shift back and forth between pilot and titan allows players to change tactics on the fly, attacking or escaping depending on the situation and extending the action vertically to new heights.
