Play San Andreas as CJ and press one key to switch into CS MODE: Counter-Strike 1.6's weapons, first-person viewmodels, crosshair, HUD, buy menu, grenades and C4, all read from your own Counter-Strike 1.6. Press it again and everything is San Andreas again. Missions, cars, cutscenes and saves are untouched.
What you need to play
GTA San Andreas for PC, version 1.0 US or 1.01 EU (the original 2005 release, or a copy downgraded to 1.0).
Not supported: the Steam / Rockstar Launcher version (2.0 and later) and the Definitive Edition. They are different programs; the launcher tells you if your copy is one of them.
Counter-Strike 1.6 installed (Steam or another copy with its cstrike folder). It is only read, never started or changed.
Windows. Nothing is written into your game folder.
If it doesn't start
Antivirus blocked csandreas.exe: the launcher loads the mod into the game the way many game tools do, which some antivirus programs dislike. Allow CS Andreas in your antivirus, then press Play again.
Other GTA mods: CLEO, ModLoader, ENB and similar mods can clash with CS Andreas. If the game crashes, try once with them removed.
What you get
One key (], on a Russian layout Ъ) switches CS MODE on and off. CJ keeps his health, money, guns and mission progress.
All CS 1.6 guns with their real viewmodels, animations and sounds: pistols, shotguns, SMGs, rifles, snipers, M249, knife, HE / flash / smoke grenades, C4 and the tactical shield.
CS shooting: damage, headshots, spread, recoil and wall penetration like CS.
CS HUD, crosshair, buy menu (B) and team / class menu (M), built from your CS files.
CS movement: jump, duck, walk, air strafing, bunny hops.
Story missions in CS: mission fighters, nearby gangs and the police fight with CS 1.6 poses, gait, guns, sounds and deaths. Your flashbang blinds them and your smoke blocks their shots. Reworked skins for Ballas, Grove Street, Sweet, Ryder, Big Smoke, Vagos, the Russian mafia, LSPD and SWAT (1.01 EU).
Riding with Smoke in Just Business and Reuniting the Families, you shoot in CS mode.
Solo play.
What's new
1.1.2
Fixed GTA 1.0 US: the CS guns in hand, crosshair and HUD were not drawn, so CS mode looked like it had no guns.
If the game crashes, the mod now notes where in its log, so the remaining crashes can be found and fixed.
1.1.1
Fixed the crash at start on GTA 1.0 US.
An unsupported GTA (Steam 2.0+, Definitive Edition) now gets a clear message instead of a plain San Andreas.
1.1.0
Story missions fought the CS way, reworked fighter skins, CS flashbang and smoke for everyone, CS shooting while riding with Smoke.
