The Armory update hit CS2 in October 2024. It brought some brand new features to the game, including the Battle Pass-like progression system called the Armory. For completing missions, players can receive cosmetic rewards. The Limited Edition Item is a CS2 collection of skins that was released specifically to add unique rewards for the Armory.
Desert Eagle | Heat Treated looks like it was forged in fire. In a way, the skin refers to the Case Hardened family. You can see clear bluish elements on the metallic body, which create unique Blue Gem variants for other skins. Heat Treated also comes with different patterns, or seeds.
XM1014 | Solitude was added to the Limited Edition Item Collection later, with the Spring Forward update in April 2025. The shotgun skin comes with a range of variants, which drastically differ from each other. You may get fluffy clouds or a mountain view. This feature makes XM1014 | Solitude really unique.
