Counter-Strike: Global Offensive

is the sequel to , running on the . Originally started as a port of for the , 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 entity and produced only static lighting) now casts harsh, directional shadow maps similar to .
A console version of (for & ) is also available, but it has not received any major updates since 2013, while the PC version of the game has been delisted in favor of , which is the port and remaster of CS:GO. CS2 also remake various CS:GO maps such as Inferno, while other features and maps introduced with CS:GO were removed.
== 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, , which runs on engine, featuring improved graphics, redesigned maps and improved gameplay. was released as a free update to CS:GO, replacing and moving it to a beta branch (), initially called 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. 
With the release of CS2, which has replaced CS:GO on Steam, the development of major updates for Counter-Strike: Global Offensive has been officially discontinued. Additionally, all of the game’s 147 achievements have been removed server-side. While the game is still playable by downloading the mentioned beta branch, as of January 1, 2024, CS:GO no longer receive security updates or bug fixes. This will likely leave the game vulnerable to remote code execution (RCE) exploits, other security risks, and unresolved bugs. With the launch of CS2, matchmaking servers for CS:GO have also been shut down, making the game playable only offline with bots, on community servers, or by connecting via IP address.
Meanwhile, when it's come to console port, the version was also discontinued early in March - June 2023 for unknown reason before the Xbox 360 Marketplace store shutdown in July 2024 (but demo version can still be playable). However, multiplayer are currently still functional on the version. The servers for the PlayStation 3 version was also quietly shut down in 2018, but remains playable and can be purchased.
== Features ==
Counter-Strike: Global Offensive has:
; FXAA anti-aliasing
: Simple post-processing effect aimed to remove jaggies on geometry and other objects at the cost of image quality, but are much faster than other anti-aliasing method, such as MSAA.
: FXAA can be also used with MSAA (such as 2X) at the same time. This benefits most lower-end PC that struggles to run MSAA 4X or higher, it also benefits models, transparent textures, and other objects that MSAA was unable to remove jaggies or staircase effect on them.
; Real-time dynamic shadows
: provides dynamic, high-resolution cascade shadow mapping for the outdoor light of .
; Lightmapped Ambient Occlusion
: VRAD can now bake ambient occlusion into the lightmaps for a map, leading to enhanced realism.
; Bump mapped decals
: decals now support bump maps.
; Scaleform (officially called Scaleform GFx)
: A vector graphics rendering engine used to display -based UI and HUD for games. CS:GO used Scaleform for the in-game HUDs and the main menu until 2018.
; VPK version 2
: New version of VPK file format. Later backported to all games.
====Newer Features====
Later features introduced to CS:GO and the .
; Phong reflections on Lightmapped materials
: LightmappedGeneric and now support diffuse Phong reflections.
; Vertex lighting for bumpmapped static props
: Static props with bump maps can now receive vertex lighting, better blending them into the environment. All static props also now receive better lighting.
; Anisotropic reflection emulation
: Brush shaders can now emulate anisotropic specular reflections using new parameters.
; Bump map blending for 
: Two bump maps can now be blended together for high-frequency and low-frequency bumpmap variation on the LightmappedGeneric shader.
; 
: A displacement shader that can blend four different materials together by luminance.
; Prop combination
: VBSP now supports combining selected static props during map compilation, increasing performance and lowering draw calls.
; Increased engine and compiler limits
: The engine now supports more entities, more models, and more displacements.
: 
; New first-person weapon lighting.
: First-person weapon view now support more detailed lighting.
; Static prop scaling
; Panorama UI
: Introduced in 2018, replacing Scaleform, Valve's new Custom GUI interface that resembles modern web design and authoring (HTML5/CSS/JS). Using .XML and JavaScript files, developers can create dynamic and clean HUDs and menus and even high-quality in-game intractable panels.
; Direct3D 9Ex / Windows Aero DirectX Extensions 
: Introduced in April 2019 update, D3D9Ex improves performance depending on GPU hardware and drivers.

== Game modes ==
Official Game Mode	Official Game Mode 	Match length 	Penalties forabandoning?	Description of official Gameplay
 	Competitive Long MatchShort Match 	20-90 minutes	 	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.
 	Wingman 	10-30 minutes	 	Like Competitive, but adjusted for 2v2 and for a smaller map or a map section, best of 16 rounds, rounds are shorter.
 	Casual 	10-20 minutes	 	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.
 	Deathmatch Team vs TeamFree For AllClassic	10 minutes 	 	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.
 	Danger Zone 	3-15 minutes 	 	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 	War Games 	 	 	
 	Arms Race 	5-10 minutes 	 	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.
 	Demolition 	10-20 minutes	 	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.
 	Flying Scoutsman 	10-20 minutes	 	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.
 	Retakes 	5-10 minutes 	 	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.
