Boot up CS:GO and load into the main menu. If you got into the CS2 beta test, you'll see a popup telling you so (or else a notification in your left-hand main menu bar with a message about the beta). Just click “Enroll” on the popup, and you're good to go! You may need to restart CS:GO to play the beta.

First things first, Counter-Strike 2 is only available on Steam. Like all of the Counter-Strike games before it, CS2 is only playable on the PC.

With Source 2 lighting and particle systems, there's an all-new look and behavior for water, explosions, fire, smoke, muzzle flashes, bullet tracers, impact effects, and more. In Counter-Strike 2 the most critical gameplay visuals have been redesigned with readability in mind.

To be eligible for a CS2 Limited Test invite players must have CS:GO Prime status, an active official competitive matchmaking Skill Group, and play majority of their official matchmaking games in one of the regions where the Limited Test is available."
