The Razorback is now classified as a melee weapon in crafting
The Chargin' Targe is now classified as a Seconday weapon in crafting
The Cloak and Dagger is now classified as PDA1 in crafting, while the Dead Ringer remains PDA2
The Gunboats and other 4th weapons for classes that were mainly obtained through random drop are now classified with a special "Token 4" for easy crafting access
As long as one Gibus in your backpack remains, you can craft Gibuses as hats. (For people with 2 Gibuses, you can craft one, but not the other.)
Trading
It's finally here!
Hats can be traded to friends known for more than a week, while weapons can be traded through any friends or through a Trading Offer sent throughout a voting system in-game, not unlike the Left 4 Dead voting system.
Untradable items are "Event" items, and any crafting items (Metal, Tokens, etc.)
All trades will be monitored by Steam Support; if any violations are made in the system, all of your items will be removed. If there is repeated violations, a VAC ban will be placed upon your profile.
