Counter-Strike — the most popular multiplayer game, has support for network and single games (with bots). Some analysts believe that Counter-Strike 1.6 is currently losing popularity as players get more powerful PCs that support modern games with better graphics and improved physics engines. In 2007 — In 2008, a reverse process was outlined — strengthening the position of CS 1.6 as a tournament discipline. Many people around the world are in no hurry to leave the ranks of virtual Counter-Strike fighters. First of all, this is due to the familiar gameplay. However, now Counter-Strike: Source is actively developing and gaining more and more popularity. The basic idea of the game — confrontation between two teams — Terrorists (Terrorist team, T) and Counter-Terrorists (Counter-Terrorist team, CT). Each player, upon entering the game, chooses the team for which he wants to play, or the opportunity to be an observer — Spectator — if it is provided by the game server settings. The purpose of the game — complete the task of the map or destroy the enemy. For completed tasks and destroyed opponents, the player receives money that can be spent on buying weapons, ammunition and equipment.
