Originally scheduled for release on January 24, which obviously did not happen, it has been revealed via The Twitter that the HD remake of 2004's Killzone has been "delayed indefinitely." Whether it is outright cancelled or just delayed with no new date in sight, the PSN only release of Killzone HD is not coming anytime soon.

Featuring four playable characters, Killzone provides several gameplay modes including single-player, multiplayer (team based and competitive) and online play for up to 12 players. Players can equip themselves with an armory of more than 27 different weapons inspired from today's modern weaponry. In particular, there are 21 first-person weapons that the player can carry, five emplaced weapons, and hand grenades. More than 11 intricately detailed environments showcase the harsh setting of a war-ridden planet, coupled with a unique graphical style designed to capture the grit and realism of intense military engagements.

For years, the success of planetary colonization has resulted in several planets to become inhabited by humans. While the majority of colonies have aligned to form the ISA, the Helghast, a ruthless, militaristic separatist faction have distanced themselves secretly planning to scale an all out war.

Killzone takes place during the initial Helghast blitzkrieg of the nearby colony of Vecta. As Vecta City's orbital defenses mysteriously fail, the Helghast have been able to land and deploy their troops rapidly and with ease. As the planetary defense forces become overrun and scattered into the city, the initial objective as an ISA member is to escort a high-ranking official to an evacuation point.
