July 8, 2010 Patch

The Engineer Update is a patch for the Engineer, the last class to have a major content pack released. The update was announced on July 5, 2010, and was released on July 8, 2010. Rather than announcing new content for the update regularly, new content was released every time 25 Golden Wrenches were found. With 100 Wrenches to be found in total, there were 4 announcements prior to the final release.
