The plot revolves around two rival groups known as the Helghast and the Vektans, who are separated by a massive wall in a futuristic city. Playing as one of the rival factions, combat quiet infiltrations or an all out attack from your enemies, as they seek to destroy your homeland. Featuring staple weapons from the previous Killzone series, this game also incorporates cool and advanced new weapons in the latest version. Levels in this version of the action game are more open and based on your stealth, enabling you to reach your objective from multiple routes. Killzone: Shadow Fall can be played as a single player or in the multiplayer mode, with most of the player mechanics available on both modes.
