Trade-Up is a feature that allows players to trade multiple unwanted items in their backpack for a chance at receiving a new, possibly better item. It is applicable only in specific situations.
Item Grade Trade-Up
Available only for items that have a designated Grade, Item Grade Trade-Up allows players to exchange ten Decorated weapons or certain cosmetic items of one grade for an item of the next higher grade. It is accessible via a sub-menu in the backpack, either through inspecting a valid Trade-Up item or an empty space in the backpack.
Trade-Up requires ten weapons or cosmetics of the same grade. Weapons may be of any exterior wear, but must all be of the same grade (Civilian, Freelance, Mercenary, etc.). Strange items may also be accepted, although Unusual items are prohibited.
After confirming the input of the required number of items, the player receives one item of the next higher grade. The resulting item is selected at random from one of the same collection(s) as the originating items; submitting multiple items from a single collection will guarantee receiving an item from the next higher grade of that collection. If all submitted items were Strange, then the output is also Strange.
In the case of Decorated weapons, the exterior wear of the received weapon is calculated based on the average wear of all submitted weapons. Therefore, inputting ten Battle-Scarred Civilian Grade Decorated weapons will result in one Battle-Scarred Freelance Grade Decorated weapon; however, if ten Factory New Commando Grade Decorated weapons are used, then the result will be a Factory New Assassin Grade Decorated weapon.
Available only during Scream Fortress 2015 and Scream Fortress 2016, Halloween Transmute allows players to trade three items for an untradable cosmetic item from a previous Scream Fortress event. It is accessible via a sub-menu when checking the details of the Soul Gargoyle.
Only certain items can be used in Halloween Transmute, regardless of trade, market or crafting restrictions of the submitted item. Excluded items include but are not limited to:
- Unique quality weapons
- Most Genuine items
- Community items
- Event-granted tools (e.g., Spellbook Magazine)
- Most Tools
- Unusual quality items
Once three items have been submitted, the player will receive a random item from a previous Scream Fortress event. The resulting item will be untradable and unusable in crafting, and has a chance to be Haunted or a Gargoyle Case; in the event of a Gargoyle Case, it becomes tradable and marketable.
For every ten transmutations, the player receives one extra bonus cosmetic item. This bonus cosmetic will be in the Haunted quality.
