The Gun Mettle Update for Team Fortress 2 was detailed tonight by Valve and if you like the campaign system for Counter-Strike: Global Offensive, then you're going to love this. For $5.99 (USD), you can embark on a three month long campaign for TF2. You pay actual money to participate in a bunch of skill-based contracts that dish out some sweet rewards such as unique weapon skins and cases.

Hey, you don't want to spend $6? No problem. Valve has a big batch of content and update ready to go for the tightwads of the gaming world as well. Tomorrow, when this whole thing kicks off, there will be three new community maps, a new Valve maps, new taunts, and a metric ton of gameplay changes and adjustments. Let's first start with the Gun Mettle Campaign info.

The Gun Mettle Campaign is a three-month event new to the Team Fortress universe. For the first time, test your mettle on a variety of skill-based contracts, with one-of-a-kind weapons and exclusive weapon cases as rewards.

GET YOUR CONTRACTS HERE
You'll be assigned two skill-based contracts each week for the length of the Gun Mettle Campaign. Every contract will give you a new challenge, as well as an advanced-level objective worth bonus points. Get a kill with a reflected projectile as Pyro. Survive 1000 damage in a single life as Heavy. Kill an airborne enemy with your secondary weapon as Soldier. Whenever you complete a contract, you'll earn a campaign-exclusive weapon or unlockable weapon case.

THE TOP GUNS
The weapons you'll get from completing contracts are one-of-a-kind. Every weapon is given a uniquely placed paint job so that it will always look a little different from anyone else's. Weapons come in six grades of rarity, and are further modified by five levels of wear, from Factory New to Battle-Scarred. (Check out the FAQ for a more detailed breakdown of rarity.)

YOUR CAMPAIGN COIN
Buying access to the Gun Mettle Campaign puts a Campaign Pass in your inventory. Just click on it to activate it, and it will transform into a Campaign Coin and throw you into the thick of things. Your coin keeps track of your progress on active contracts, levels up as you complete them, and shows off your level to other players on the scoreboard.

Once you complete those contracts, you get some visually unique weapon skins to add to your collection, a sample of which can be seen below.


Get really lucky, and you'll get your hands on an unlockable crate that could have a weapon with a Strange modifier on it, a Stat Module, a chance to be Unusual, or sometimes a chance at having both.

But what about the free content? Well, here it is The free content includes three community created maps: Borneo, Suijin, and Snowplow. There will be a new Valve Control Point map, Powerhouse also added to the mix.


On top of that, you can now "steal" other players' weapons if they were of the same class as you. Think of it as a test drive for a weapon you don't have. You don't get to keep it as it does go away when you die and respawn. Beyond that, there will be new Taunts such as the Kazotsky Kick...


And the Box Trot....


... and The Proletariat Posedown.


Naturally, there will be new achievements added for the Powerhouse content. Until this content is released tomorrow, be sure to check out the full details on the update, including a brand new TF2 comic. The list of changes can be found below.
