Half-Life 2 (abbreviated as HL2) defines a new benchmark in gaming with startling realism and responsiveness. Powered by then-new Source technology, Half-Life 2 features the most sophisticated in-game characters ever witnessed, advanced AI, stunning graphics and physical gameplay. This was the first game requiring installation of Steam when it came out back in 2004.
Half-Life 2 is the sequel to the 1998 Half-Life. A sequel to Half-Life 2 was released in 2006, titled Half-Life 2: Episode One. A virtual reality prequel was released in 2020, titled Half-Life: Alyx.
Half-Life 2 was later ported for the Xbox console in 2005, as well as for the Xbox 360 and PlayStation 3 in 2007, bundled under The Orange Box.
A major update (Half-Life 2 20th Anniversary Update), has been released on November 16, 2024 to celebrate the 20th anniversary of the game. It adds Steam Workshop support, developer commentary, fixing various bugs, and both episodes (Episode One, Episode Two), aswell as Lost Coast now accessible directly on Half-Life 2 menu. There are also many other changes to the graphics, such as "Very High" shaders that enable Bicubic lightmap filtering, and option to use classic fire/blood particle effect.[1]

Limitations/Bugs
- For more Half-Life 2 bugs, see this GitHub page.
This section only list various bugs that are commonly encountered.
☐ Unresolved bugs
None.
☑ Resolved bugs
- Missing lighting on LDR / LDR with Bloom
- Previous version of Half-Life 2 from 2010 to 2023 lacks LDR lighting on multiple game levels (starting from Black Mesa East (
d1_eli_01) until the end of Nova Prospekt). This means that if HDR is disabled (by selecting "None" or "Bloom only" in HDR settings), mat_fullbright will be set to 1, disabling lighting and making everything bright and flat (relevant GitHub issue). Because of this, HDR is required to play the game until this is fixed.
This issue is not affected in the previous version of the game (which uses an older version of Source (Source 2006) and all of the maps lighting are compiled in LDR only), and is fixed in Half-Life 2: Update, aswell as 20th Anniversary update.
- Dropship NPC gun broken
- There was a bug with the Dropship's gun that was unable to turn, this makes the Sandtraps chapter much easier.[2] This bug was introduced with Source 2007 engine branch and later, affecting both the console release of the game on X360/PS3 (remains unfixed) and later in 2010 with the Source 2009 engine update on Mac & PC release.
Fixed in the current Steam version since 2022's the Steam Deck update of Half-Life 2. However, there are many third-party Source mods (including Half-Life 2: Update) which may or may not include this fix; this page details how to fix it in your mod.
Other limitations
Important:The macOS (OS X) version of this game does not work on macOS Catalina (version 10.15) or later due to the removal of support for 32-bit-only apps.As of May 26, 2010 (Mac), and later June 2010 on Windows, the branch of Source under which Half-Life 2 originally ran on Source 2006 no longer exists on Steam, and subsequently replaced by the updated Source 2009 (which later was upgraded again to Source 2013). Very old mods which base themselves directly on the game (as opposed to Source SDK Base) are unlikely to work any more.
This also meant that support for running Half-Life 2 on Windows 9x/ME/2000 have been also dropped.
Technical notes
- In the 2006 version of the game, being underwater at d1_canals_01, or in some area on that same map can cause performance drops. Fixed since 2010 with the engine update.
- Although Source mods are often described as being "for Half-Life 2", they actually use the Source SDK Base. SDK Base is available to anyone who owns any Valve Source game and provides all of Half-Life 2's content (except maps and vcd scenes) on a static branch of the engine.
- The Half-Life 2 Collectors Edition, which ships with the 2004 version of the game, does not require Steam to run or update (similar to the latest version), which means that it will run on older systems with Windows 2000 and earlier. Since around 2010 or 2013, Half-Life 2 no longer requires Steam to run after installing it through Steam, but features such as Achievements will be unavailable.
- The 64-bit Windows version of Half-Life 2, which existed around 2005-2006, is no longer available.
