The gameplay will strongly resemble that of Killzone 2 albeit with several tweaks and changes. Similar to the first Killzone, the game will take place in various harsh environments such as Arctic landscapes, a lethal alien jungle, nuclear wastelands as well as space battles rather than only the city-scape environments which were present in Killzone 2. Another notable new feature is the ability to use jet packs in the game, which were seen in Killzone: Liberation, however, these new jet packs will be used in a different manner than that of those that appeared in Killzone: Liberation.
The game will also feature a revamped close combat melee system which include new brutal melee attacks as well as the ability to string together multiple attacks in a combo. Killzone 3 will feature fully destructible environments which is an improvement from its predecessor, which featured only partially destructible environments in limited areas. A new weapon called the WASP has also been revealed, which acts as a multi-firing Rocket Launcher. In the July 2010 edition of GameInformer Magazine, it was revealed that the WASP rocket launcher will have a primary fire and a secondary fire, which leaves to speculation that secondary fire for various weapons will return as seen in the original Killzone.
