Valve announced that the Counter-Strike developers and Valve had teamed up. Since then, Counter-Strike has been available to buy. The latest version of Counter-Strike is 1.6, released on September 15, 2003, a few days after Steam launched, since then, the game continues to receive updates, like many other GoldSrc games. Since the release of later Counter-Strike games, it was commonly and retroactively called Counter-Strike 1.6 (CS 1.6 for short) to distinguish it from other Counter-Strike games.

Workaround: ReGameDLL_CS may solve some problems but introduce others. This is a server-side mod; clients do not need to modify their installation to connect to servers running ReGameDLL_CS.

Versions
The final major version of Counter-Strike is 1.6, released on September 15, 2003, few days after Steam launched. Since then, Counter-Strike, like many other GoldSrc games, now only receiving minor updates (such as engine and security updates). Previous (WON) version of Counter-Strike, such as 1.5 are still remains playable online until 2004 when WON master servers were completely shutdown, forcing user to use direct IP workaround, patching the game to use WON2 servers, playing LAN/Offline or simply update to 1.6.
Dedicated server
Bots
Warning:There are no bots in the game, unlike some later titles.Workaround: All Counter-Strike 1.6 maps can be run in Counter-Strike: Condition Zero to use CS_Bot.
Workaround: A third party option can be used:
- zBots had commands like bot_nav_merge https://forums.alliedmods.net/showpost.php?p=268544&postcount=14
- YaPB https://yapb.jeefo.net
and others. See http://www.bots-united.com.
Mods
There are a few mods that significantly change the gameplay.
Notes
- Client-side fps_max is capped at 100 (on Steam version), formerly 72 (WON/Retail, like
Quake) but can be changed with 3 commands:
- gl_vsync 0 // Disable VSync (Vertical Sync) - this options prevents screen tearing at the cost of lower and varied FPS and more input lag.
- fps_max "XX" // Replace "XX" with your desired FPS value.
- fps_override 1
- Some sources advocate against setting fps_max above 100, as it can cause player movements to slow down significantly (more noticeable when jumping).
- The server-side tickrate is 60.
- Counter-Strike had built-in voice communication since 1.3.
Trivia
- The pirated copies of 1.6 in Russia, most of Asia and several other countries had a menu theme that is not in the Steam version. The most frequently used track was the main theme made from Condition Zero Deleted Scenes by Zak Belica, as well as cut-down version which was also played on the Xbox version of
Counter-Strike.
Tip:This behavior can be replicated by placing an MP3 file named 
gamestartup.mp3in the
cstrike/media/folder.
- The Versions before 1.6 of Counter-Strike were free and non-standalone (meaning you needed to own a base game to play it) mods for Half-Life WON due to Counter-Strike not being owned by Valve yet and still were only operated by Minh "Gooseman" Le and Jess Cliffe. [confirm][Clarify]
- The font used for the menu title in 1.5 is facelift. The font used for the menu items is Silk Remington Pro Seven.
