One of the many flavours of Killzone 3 available to customers who pre-ordered contained the so-called Retro Map Pack, a pair of maps from predecessor Killzone 2: Salamun Market and Blood Gracht.

If you weren't able to pick up the maps for free, you're now able to download them from the PlayStation Store for $4.99, or £3.99 / €4.99 in Europe, where the game launches on Friday.

Stay tuned for our review of Killzone 3 and its Move controls in the near future.
