In many ways, it's not. Like any other class update, the War update will reveal three new weapons each for the Demoman and Soldier throughout the week, as well as some maps, achievements, and surprises, right up until the day of release, when everything we've been teasing goes live.

Where the War update differs from other class updates is that we've decided to mix things up a little with, as the Administrator would say, "a healthy competition." A secret, exclusive seventh weapon has also been developed by the TF2 team. In other words, either the Soldier or the Demo (but NOT both) is walking out of this update with one more weapon than the other. If you want your class to have it, you're going to have to fight for it. The more Demomen you kill as the Soldier class will help ensure the Soldier gets the weapon at the end of the week. The more Soldiers you kill as the Demo will help the Demo class get the exclusive seventh weapon. Check back daily to see how your class is doing at the War hubpage — this is also where you'll see links to all the leaked previews of the weapons, maps, and surprises releasing soon with this update.
