Unfortunately, you can't play CS2 on your smartphone using standalone apps for Android or iOS. However, you can run CS2 on your phone using game streaming services like GeForce Now or Steam Link. The main drawback of game streaming is that their services come with a cost.

If you don't already have CS:GO, you will have to download the game from Steam by pressing “Install.” Once it's downloaded on Steam, open it and click “Play.” You can now play Counter-Strike 2!

Key differences between CS2 and CS:GO include: Game Engine: CS2 uses the Source 2 game engine, offering better visuals and effects. CS:GO used the original Source engine for over 11 years.

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.
