1.08, a small Killzone: Shadow Fall update has released in preparation for an imminently larger one in the coming weeks. We reported a few days ago that two new maps will enter rotation and that a full-on multiplayer expansion will release.
For now, 1.08 has dropped and adds much improved network reliability, meaning you should lag out and crash a lot less online. Your experience should also be much more seamless and less marred with hiccups and action-stutters.
There are also some crash fixes within the update, working on random breaks in the game that cause you to drop to the menu or freeze the game up entirely.
