Things Worth Knowing

These are the kinds of details that make CS2 more than just a texture update.

01 // Launch

CS2 fully replaced CS:GO

Counter-Strike 2 officially launched on September 27, 2023, and shipped as the direct free upgrade that replaced CS:GO on Steam.

02 // Engine

It moved to Source 2

The jump to Source 2 changed lighting, materials, map tools, and the overall feel of the game, not just the menu art.

03 // Networking

Subtick was the big tech headline

Valve built CS2 around subtick timing so actions like shooting, jumping, and grenade throws can be registered with more precise input timing.

04 // Utility

Smokes are volumetric now

They react to the world instead of acting like flat visual walls, which is why grenades and bullets can temporarily carve openings through them.

05 // Maps

Valve sorted maps into three rebuild levels

Some maps were only touched up, some were upgraded with new lighting and materials, and others were rebuilt much more deeply for CS2.

06 // Ranked

Premier changed the ranked vibe

Premier mode brought a map veto flow and a visible CS Rating, which made high-level ranked play feel closer to organized competition.

07 // Loadouts

You no longer bring every buyable gun

CS2 uses an active loadout system, so players choose a smaller set of weapons before the match instead of having every option available at buy time.

08 // Visuals

Old skins can look different in CS2

Because the lighting and material rendering changed, some finishes, stickers, and gems look noticeably different compared with how they appeared in CS:GO.

09 // Trade-Ups

Float math still rules skin outcomes

Trade-up contracts still care about the average float of the 10 inputs, which is why tiny float differences can change the wear band of the result.
