Dubbed ‘the ultimate first person shooter for PlayStation 3′, Sony unveiled Killzone 2 at a particularly exclusive media event at E3 in Santa Monica last night. Developed by Guerrilla Games, it has players in the midst of the action between the ISA and Helghast army, with the emphasis on gritty realism and extreme detail.

“There have rightly been high expectations for Killzone 2 since we shared the vision for the title back in 2005,” said Phil Harrison, president of Sony Computer Entertainment Worldwide Studios. “Guerrilla have worked hard to focus the power of PlayStation 3 to realise their true vision for the game. With incredible action, drama-fueled gameplay sequences, and a vast array of weapons and vehicles, Killzone 2 defines a new benchmark of our industry.”

Here’s more details of Killzone 2 from the press release

Two years after the Helghast assault on Vekta, the ISA is bringing the fight to the enemy’s home world of Helghan. Taking the role of Sev, the battle-hardened veteran of the special forces unit known as the Legion, players will embark upon a mission to the planet Helghan to capture the Helghast leader, Emperor Visari, and bring the enemy’s war machine to a halt. For Sev and his squad, the invasion of Helghan is just the beginning. Tasked with securing Pyrrhus, the Capital City, the team quickly discovers that the Helghast are a formidable enemy on their home planet. Not only have they adjusted to the planet’s hostile conditions, they have also harnessed a source of power from the environment that can be used against the ISA. Sev and his team soon discover the fight is greater than simply addressing the enemy forces; the Legion must also learn how to handle the effects of the fierce enemy planet.

With an extensive, story-driven single-player mode and thrilling multiplayer mode, Killzone 2 offers a host of new elements that caters to both hardcore and casual gamers alike. The game features highly atmospheric environments that respond accurately to weapon fire as players storm through the world of Helghan. The harsh climate and conditions of Helghan are also a factor, forcing players to adapt new tactics to survive. Proprietary tools and technology such as deferred rendering techniques are implemented to create advanced effects, such as ultra-vivid and detailed character animations and environments. Advanced cinematic effects are used to provide unprecedented visuals, including motion blur, internal lens reflections, and depth-based color grading that will letplayers experience gameplay that is sharp, detailed, and vibrant.

Additionally, Killzone 2 supports 7.1 surround with location-specific audio, providing players the opportunity to experience sound and music that are not only dynamic but in context to indoor and outdoor locations.
