A: Completing contracts earns you weapons or unlockable weapons cases of various wear and rarity grades from one of four collections. Weapons from the TeuFort and Craftsmann collections are available through completing contracts, while weapons from the Powerhouse and Concealed Killer collections are only available in weapon cases.
A: Campaign-exclusive weapons are one-of-a kind. Every weapon is given a uniquely placed paint job so that it will always look a little different than your friends'. Weapons further come in six grades of rarity (Civilian, Freelance, Mercenary, Commando, Assassin or Elite) further modified by five levels of wear (Factory New, Minimal Wear, Field-Tested, Well-Worn and Battle Scarred). Completing contracts will earn you either a weapon from a collection with rarity grades 1-4, or an unlockable weapons case that has weapons with rarity grades 3-6. Campaign-exclusive weapons found in unlockable cases will also have a chance to contain Strange capability, a rarer chance at being Unusual, and a highly rare chance to have both.
A: No. Campaign-exclusive weapons are purely cosmetic.
A: Crates are dropped randomly and contain a random selection of items. Weapon cases are only accessible through participation in the campaign, are exclusive to the campaign and can only be received as direct rewards for completing contracts. Crate keys will not open weapon cases. Only campaign-specific case keys will open weapon cases.
A: Purchasing access further into the campaign will still earn you the same number of contracts as someone who purchased access on day one. Access will no longer be available for purchase through the last month of the campaign.
A: You get to keep all weapons cases, keys, weapons and other items you have accumulated during the course of the campaign. However, you will no longer be able to complete contracts once the campaign is over.
A: No. Crate drops, timed drops and item purchases are all still fully functional. The Gun Mettle Campaign is entirely additive to your play experience. Nothing goes away.
A: Yes. Campaign-exclusive weapons and cases have identical functionality to existing economy items.
A: A portion of profits from the sale of Campaign Passes will go to the creators of the maps featured in the campaign. If you would like your map to be considered for future campaigns, submit them to the Maps Workshop
A: The majority of the update works just fine for DirectX 8. Contracts, drops, coins and maps—they all work! Unfortunately, the uniquely decorated weapons do not. When you are playing with DirectX 8, you will only see the basic, undecorated weapons. This is true both of your own and others' weapons. To gain access to unique weapon decorations, run Team Fortress with DirectX 9. Players running DirectX 8 should remove mat_dxlevel from their config files and add -dxlevel 95 to their launch options.
