Killzone: Shadow Fall has a 1.05 update available now. This patch should download and install immediately.
Gamers have consistently criticized chapters 7 and 8 as being the least enjoyable parts of the main campaign, so the patch has addressed these issues. The end of chapter 7 is now shorter, and chapter 8 is now a bit easier. I hated these chapters the most myself, so I am personally curious how this patch changes them.
In addition, the patch fixes numerous UI problems and crashes some have experienced in the multiplayer. The update also features left-handed support, allowing players to switch the controls for the analog sticks.
