How to choose
Choose Counter-Strike 2 for the current competitive Counter-Strike. CS 1.6 offers the original classic style, Condition Zero adds solo challenges and Deleted Scenes, and Source uses the earlier Source engine. Global Offensive is a separate older edition; confirm the exact client used by friends and servers.
CS2 and the current CS:GO listing are free; CS 1.6, Condition Zero and Source have paid licenses. Older game requirements do not describe the needs of current Windows and Steam. For a modest PC, check the complete setup, and never use CS 1.6 specifications to estimate CS2 performance.
