The fourth instalment in the Killzone series has been announced for the PS3. Killzone 3 which will be in 3D, is developed by Guerilla Games and published by Sony Computer Entertainment is set to release in 2011.

The first person shooter is said to have a story similar to that of David and Goliath. It continues from where Killzone 2 ends and will feature Sev, the main protagonist. The game will give a deeper insight about the Heghan culture and will showcase whatever humanity they have left in them. The story will not be as dark as the previous one, though it will not be too light-hearted as it is a war game.

Guerilla is making strong efforts to develop a strong storyline and have also hired Hollywood actors for voice-overs. Though the gameplay will be similar to that of Killzone 2, there will be a lot of improvements. The game will take place in new environments such as Arctic landscapes, a lethal alien jungle and nuclear wastelands unlike the predecessors which took place in city environments. The game will also feature new move sets and weapons apart from a jet pack. The new set of weapons includes the “Wasp” which is a multi firing rocket launcher.

The trailer of the game looks promising. Check it out after the jump.
