Counter-Strike: Global Offensive Counter-Strike: Global Offensive is the sequel to Counter-Strike: Source, running on the CS:GO engine branch. Originally started as a port of Counter-Strike: Source for the Xbox 360, it was later expanded and eventually turned into a new Counter-Strike game.

Technology-wise, Cascaded Shadow Maps has been implemented, wherein outdoor lighting (which was previously handled by a light_environment entity and produced only static lighting) now casts harsh, directional shadow maps similar to env_projectedtexture.

A console version of Counter-Strike: Global Offensive (Console) CS:GO (for Xbox 360 & PlayStation 3) is also available, but it has not received any major updates since 2013, and hasn't been replaced by Counter-Strike 2 Counter-Strike 2.

The PC version of the game has been delisted in favor of Counter-Strike 2 Counter-Strike 2, which is the Source 2 Source 2 port of CS:GO. CS2 also remake various CS:GO maps such as Inferno.

Development and Updates

On December 6, 2018, the game became free-to-play and introduced a new battle royale game mode called "Danger Zone".

On September 27, 2023, the long-awaited sequel to CS:GO, Counter-Strike 2 Counter-Strike 2, which runs on Source 2 engine, featuring improved graphics, redesigned maps and improved gameplay. Counter-Strike 2 was released as a free update to CS:GO, replacing and moving it to a beta branch (csgo_legacy), initially called csgo_demo_viewer for viewing old CS:GO demos, but later renamed to "Legacy CS:GO Version", partially because Valve recognizing that some users are unable to run CS2 due to their hardware or operating systems are incompatible with the game.

Due to the release of CS2 which replace CS:GO on Steam, this meant that the development of major update for Counter-Strike: Global Offensive officially discontinued, aswell as all of it's 147 achievements has been removed server-side, but the game can still obtainable by downloading the mentioned beta branch, however as of Jan 1, 2024, CS:GO is no longer being maintained with security updates and bug fixes, which will likely leaving the game vulnerable to RCE, other exploits and aswell as bugs remains not fixed. Matchmaking servers for CS:GO was also shutdown with the launch of CS2, therefore this game is only playable offline with bots, community servers or by connecting via IP address.

CS:GO on the console on the other hand, has not been yet discontinued, and remains sold from retailers, but the digital version sold on Xbox 360 Xbox 360 was also discontinued early, possibly because of Xbox Live Marketplace was planned to be closed in July 2024, or for unknown reasons. Multiplayer are also functional on the Xbox 360 version.

Description of official Gameplay
Csgo icon competitive.png Competitive
  • Long Match
  • Short Match
20-90 minutes Yes The classic game mode: Two teams of 5 players fight in a best of 30 rounds (Short Match: 16). In Bomb Defusal scenarios, Terrorists must plant a bomb at a target and defend it until it explodes - Counter-Terrorists must either stop them from planting or defuse the bomb before it detonates. In Hostage Rescue scenarios, Counter-Terrorists must find and escort a hostage - Terrorists must stop them. There are skill groups for ranked matchmaking so that ideally players are matched with enemies of a similar skill level. In unranked matchmaking, these skill groups are also regarded but not adjusted.
Csgo icon wingman.png Wingman 10-30 minutes Yes Like Competitive, but adjusted for 2v2 and for a smaller map or a map section, best of 16 rounds, rounds are shorter.
Csgo icon casual.png Casual 10-20 minutes No Like Competitive but not binding ("casual"), with simplified and shortened gameplay: best of 15 rounds, shorter freezetime per round, no friendly fire, no team collision, free armor and free defuse kit/cutters.
Csgo icon deathmatch.png Deathmatch
  • Team vs Team
  • Free For All
  • Classic
10 minutes No This is a single 10 minute round with instant respawns. The player's goal is to eliminate as many enemies as possible with whatever weapon they wish to use. Weapons are free and only rifles, SMGs, heavy weapons, pistols and the Zeus x27 may be bought. Players have a short invulnerability period to buy weapons before moving.
Csgo icon dangerzone.png Danger Zone 3-15 minutes No A Battle Royale mode played on big maps where players win by being the last man (or team) standing. The game starts with all players choosing an insertion point at which they rope down from a helicopter. There is a Danger Zone that starts from the map's borders and advances, making the playable area smaller and smaller and inflicting damage to players touching it. This game mode features numerous unique weapons and entities.
War Games
Csgo icon skirmish armsrace.png Arms Race 5-10 minutes No This is a single extended round with instant respawn. All players start with the same weapon and get a new one each time they kill an enemy. The progression of unlocked weapons ends with the knife. The first player to get two kills with every weapon plus a kill with the golden knife wins the match.
Csgo icon demolition.png Demolition 10-20 minutes No This is a fast paced mix of bomb planting and gun progression. There is no buying, you start with a rifle and if you get a kill that round, you get a progressively weaker weapon in the next round. Best of 20 rounds.
Csgo icon skirmish flyingscoutsman.png Flying Scoutsman 10-20 minutes No Like Casual but every player has a fixed loadout: A Scout and a knife. There is low gravity and no inaccuracy in mid-air, allowing higher and longer jumps and precise shooting, too.
Csgo icon skirmish retakes.png Retakes 5-10 minutes No Each round, 3 Terrorists spawn on a bomb site with a bomb being planted and 4 CTs spawn at fixed locations around it. Each player can choose a loadout card at round start.

Giving Weapons

To give yourself a weapon, you can use the cheat command give <entityname>, which should spawn a specified weapon inside the executing player, for example give weapon_awp. Knives and Danger Zone melees might instantly be removed by the game when they would spawn; To overcome this, one can use the command sequence give <entityname>; ent_fire <entityname> addoutput "classname weapon_knifegg" (in one line!) so that the entity "becomes" an entity that is not removed by the game in the same tick. Note that some weapons have a different classname after being given, e.g. give weapon_axe; ent_fire weapon_melee addoutput "classname weapon_knifegg".

Map driven item giving can be done with game_player_equip. To equip weapons using VScript, a game_player_equip entity can be created, used and removed.

Manipulating Weapons

Weapons can be manipulated via I/O, e.g. with ent_fire, and even more using VScript. All weapon entities support the inputs Kill, SetAmmoAmount <int>, SetReserveAmmoAmount <int>, ToggleCanBePickedUp, for example the command ent_fire weapon_ak47 kill removes all AK-47s in the map. To give some inspiration, if weapon is the VScript handle of a weapon entity, we can use weapon.Destroy() to kill it, weapon.GetOwner() == null to check whether it is dropped (true) or carried by a player (false), EntFireByHandle(weapon, "SetReserveAmmoAmount", "0", 0, null, null) to remove its reserve ammo and much more.

Note.pngNote:When the weapon is killed that a player has deployed, their viewmodel will be broken until they deploy another weapon.
Tip.pngTip:There are weapon classes whose entities initially have an identical classname keyvalue after being spawned, even though they were created from different classnames. This makes it impossible to target only one of these weapon classes in the I/O system such as MP5-SD and MP7 entities, because entities of both classes will have the classname "weapon_mp7" after being spawned, so firing I/O events to weapon_mp5sd won't have any effect because there is no entity with that classname. This problem can be bypassed in VScript: If we find an entity with the classname "weapon_mp7", we can identify whether it is actually an MP5-SD or an MP7 by checking whether entity.GetModelName() returns either "models/weapons/w_smg_mp5sd_dropped.mdl" or "models/weapons/w_smg_mp7_dropped.mdl". Other entities whose classname changes on spawn are the USP-S, CZ75-Auto, R8 Revolver, M4A1-S, Rescue Kit, Wrench, Hammer, Axe and all knives except weapon_knife and weapon_knifegg.
