If you are playing Counter-Strike Online 2 for the first time, it might look intimidating compared to the more direct menus in other Counter-Strike games, not to mention the possible language barrier.
The Game Basics page walks you through the core aspects of the game. For a detailed walkthrough of every feature in the game, check out the User Interface guide.
This is where you manage your loadout, change weapon skins, main character(s) and costumes. These are separated by categories; Weapons > Pistols/ Shotguns/ Rifles and so forth.
Skin qualities are ranked by grades. Naturally, the lowest-grade spray skins are categorized as C-grades, camouflage-style as B-grades, textured finishes as A-grades, and naturally gold skins bear the S-grades. They are solely for cosmetic purposes and therefore do not affect gameplay in any way. What to do with the low-grade skins though? Combine them.
You are also able to configure the three available loadouts for Team Deathmatch/ Deathmatch through the Inventory. Rather than manually setting the next weapons to respawn with, pressing the F1, F2 and F3 keys respectively automatically equips your character with the pre-defined loadout until the game ends.
