One of the on screen character models of the E3 2007 trailer use the same amount of polygons as an entire level of Killzone on PS2.
The level shown in the demo was that of the Helghan capital Pyrrhus, a possible reference to the king of the Molossians. The name may also be evocative of the Helghan style of warfare.
It has been revealed that the one Killzone 2 level shown at the pre-E3 event weighed in at roughly 2.05GB.
Takes roughly the same amount of polygons to render a single character's face in Killzone 2, as an entire level in Killzone.
The score was recorded at the world famous Abbey Road Studio 1 in London; the same studio where many movie scores such as La guerra de las galaxias (1977) and Harry Potter have been recorded. Recording took place over 2 days, with strings on day 1 and brass & woodwinds on day 2 with a separate choir session in the evening.
