By Matt Porter: "Hi, everyone. We’re very pleased to announce the launch of the second update for Killzone: Mercenary.
Firstly, we need to start off with the bad news. You’ll see that the patch size is similar to that of the previous patch, and you’ll need a spare 1190MB in order to download it. When this new patch installs, the first patch will essentially be deleted, but you will need the extra space initially. This download is necessary in order to pave the way for future planned revisions to the game"
