According to Sony, in the game the Helghast are fighting for the right to exist. The war is said to devastate planets, and the state of the feud is similar to Cold War Berlin.
A demo featured slow motion effects and landing craft similar to those seen in Killzone 3. The player chased after a Helghan, hung from a ship as he was shooting soldiers, then jumped to a nearby platform and detonated to destroy the ship.
The news confirms rumors that emerged earlier this month, stemming from anonymous sources who leaked the title. Last year, Guerilla itself confirmed that it had three projects in the works.
This marks the second Killzone game on the way, joining Killzone: Mercenary for Vita, which will arrive in September.
