The long awaited, final class update, is coming this Thursday. The Engineer update will offer new weapons and achievements, and maybe some new maps and hats. Valve hinted at the update in a comic posted at the end of last week, which also offers some insight into the history of TF2. The first new weapon for the Engineer has been revealed, and is an upgrade to the shotgun. It provides critical hits based on how effective your sentry was. Also introduced over the weekend was the Golden Wrench, a limited item that is produced through crafting. Discuss your thoughts on the update in the forums. I'll be busy trying to get my hands on that wrench.
