Sony has announced that the original Killzone will be released later this month on the PlayStation Network in North America. However, it won't be getting remastered.
Unlike many other PlayStation 2 games that have been re-released on the PlayStation 3 in HD, Killzone won't be remastered at all and will be a straight port from the PS2 version.
The game will cost $9.99 and it will be released on the 24th of January in North America. No European release date has been touted at the present time.
