You've (perhaps) read my impressions of Killzone 2, now read the official Sony line in the Killzone 2 press release after the jump.

The Ultimate First-Person Shooter Emerges, Introducing Players to an Intense
'Theater of War' With Killzone(TM) 2 for PLAYSTATION(R)3

Highly Anticipated Follow-Up to the Top-Selling Killzone(TM) Delivers Next-Gen
Gameplay, Stunning High Definition Graphics, and Ultra-Realistic Combat

SANTA MONICA, Calif., July 11 /PRNewswire/ — Sony Computer Entertainment
America Inc. announced the 2008 release of Killzone(TM) 2, available
exclusively for the PLAYSTATION(R)3 (PS3(TM)) computer entertainment system.
Developed by Guerrilla Games, a wholly owned subsidiary of Sony Computer
Entertainment, Killzone 2 throws players back into the midst of a hostile and
dramatic ongoing battle between the ISA and Helghast army. Following events
and action from the original Killzone for PlayStation(R)2, Killzone 2 sets a
new standard for next-gen gaming by delivering intense warfare with incredibly
lifelike character animations, highly detailed and destructible environments,
realistic physics, and advanced levels of artificial intelligence (A.I.).
Unveiled for the first time Tuesday evening at an exclusive media event in
Santa Monica, the Killzone 2 demo awed guests with action-packed sequences
full of detail and game variety, sure to draw players right into the heart of
battle. Once again set in an extreme post-modern war, Killzone 2 utilizes the
power of PLAYSTATION 3 to deliver a striking graphical style that showcases a
gritty realism unique to the Killzone franchise.
"There have rightly been high expectations for Killzone 2 since we shared
the vision for the title back in 2005," said Phil Harrison, president, Sony
Computer Entertainment Worldwide Studios. "Guerrilla have worked hard to
focus the power of PLAYSTATION 3 to realize 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."
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 let players 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.
