War Games takes place on the Pilot-Titan combat scenario field of Hammond Industries Pilot Combat Certification Simulator, or Titanfall's beginning training course, with elements combined from Angel City and Airbase. Unlike all other maps, players will begin inside of a combat simulator module. Gameplay is identical to all other maps, except enemies will vanish into a blue haze when killed, as it is a simulator, and not a real battle. The defeated team still must evacuate into a dropship at the end of the match.
The design of the map is a blend of city settings, and the smooth white walls of the training grounds. Various "glitches" in the map are seen as orange or blue pixels on surfaces. The sky is actually a domed ceiling.
War games is probably the second hardest map out of all in frontier defense mode. The first wave of the match starts off with A few squads of sniper spectres and is assisted by numerous regular spectres. The second wave will be a mix of both regular spectres and a three platoons of Grunts along with a few automated Titans. The third wave will start off slow with only grunts attacking before IMC Titans (Armored Company Sierra) this wave requires a powerful defense as the sheer number of enemy automated Titans can overwhelm new players with or without their Titans. Though it offers the standard three retries unlike rise which only offers 2 retries.
