Killzone Mercenary has been patched, and according to Guerrilla Cambridge, you will need an extra 1190MB lying around in order to download it. However, once the new patch installs, the first patch will be deleted, so you will only need the extra space initially. This download is necessary for future planned revisions to the game, and the studio is looking into reducing the overall size of the title so that it can free up more memory card space. The main focus for patch 2 targets connectivity issues and provides a better distribution of respawn points across all game modes. Load-out slots not being unlocked, in addition to problems with the melee medal have been addressed, and a number of stability fixes, to address some of the crashes that have been reported have been addressed as well.
