Valve’s Counter-Strike 2 is live. It replaces CS:GO on Steam, offering the “largest technical leap” in the series. Announced in March, CS2 overhauls almost every aspect of the game, with updated maps, dynamic smoke grenades, and precise “sub-tick updates.” This marks Valve’s fourth major release in the series, and CS:GO remains wildly popular, with a record 1.5 million concurrent Steam players.
