Huntsman Case



Breakout Collection

Weapons skins come in 7 different quality grades, generally signifying their rarity and value.

White (Common) - Consumer grade
Example:
Light blue (Uncommon) - Industrial grade
Example:
Darker blue (Rare) - Mil-spec
Example:
Purple (Mythical) - Restricted
Example:
Pinkish purple (Legendary) - Classified
Example:
Red (Ancient) - Covert
Example:
Gold (Exceedingly Rare) - ★ (Melee Weapons)
Example:

In the Steam Market and Inventory, all skins are in white with the exception of the knives in Purple, the StatTrak weapons in Orange, Souvenir weapons in Yellow, and self-made Prototype skins in Green.

StatTrak guns are a variant of normal unbloxable weapons, they mark kill that you do ingame
(no bots kills), they worths more than Non-StatTrak version.


Souvenir guns can be unboxable by DreamHack Souvenir Case and they has a Souvenir Sticker.

Items come in a random paint quality when they are dropped or uncrated.
The paint quality hierarchy is the following, from worst exterior to best:

• Battle-Scarred
  
• Well-Worn
  
• Field-Tested
  
• Minimal Wear
  
• Factory New
  

*The skin in the pics is M4A4 | Faded Zebra (Just an example)

There is currently no way to refresh the paint of a weapon.
Note also that a weapon will not degrade over time; a weapon skin will stay in that state forever.

There are different looks of weapons, for example, there is a whisker version of the "Field Tested" which is practically the same as the "Minimal Wear" to a bug, but it is more rare than normal "FT"

Some weapon skins don't have all exteriors, examples:

• Asiimov = Battle Scarred / Well-Worn / Field Tested
  
• Fade = Minimal Wear / Factory New
  
• Slaughter = Field Tested / Minimal Wear / Factory New
  
• Boom = Field Tested / Minimal Wear / Factory New
  And MORE...
