==Game Information==
Half-Life is a critically acclaimed Sci-Fi first person shooter developed by Valve Software and published by Sierra in 1998.
==Version==
I tested using retail Half-Life version 1.1.1.0 (final retail patch).
I also used the "High Definition Content" from the Blue Shift expansion disk, though that has no bearing on the fix; only on the content of the screenshots I've provided.
==Method==
Valve added native widescreen support to the Steam version of Half-Life (Detailed Report), but the non-Steam version requires a Hex editing hack and a manual FOV tweak. Instructions for the hack are located here. The fix only adds resolutions for the OpenGL renderer; not the software or Direct3D renderer.
==Screen change==
Hor+ depending on modifiable FOV variable.
4:3 gameplay screenshot:
1024x768 - default_fov 90
16:10 gameplay screenshot:
1440x900 - default_fov 100.39487232
16:9 gameplay screenshot:
1280x720 - default_fov 106.270273206
==Supported resolutions==
List of widescreen resolutions the game successfully ran at: 1024x600, 1280x720, 1280x768, 1280x800, 1366x768, 1440x900
List of widescreen resolutions that were not tested: 1680x1050, 1920x1080, 1920x1200, and above.
List of widescreen resolutions the game fails to run at: N/A
==Singleplayer anomalies==
The entire game takes place in the first person perspective with the correct FOV used throughout.
==Multiplayer support==
Half-Life originally supported online gaming through the WON network, but those servers have since been shut down. There are unofficial recreations of the network (see: Steamless Project, WON2) that allow you to play the retail game online (at the time of this posting).
Half-Life also supports LAN gaming which does not require WON authentication.
This hack works fine in multiplayer, but since it does make changes to the executable, anti-cheat software installed by the server administrator may or may not detect it and ban the client. Server operators can force a limit on the FOV variables, but by default there is no limit.
==Surround support==
I have no means of testing surround support.
==HUD stretch==
The HUD and weapon models scale properly.
==Cut-scenes==
Half-Life has no cut scenes.
==Grading==
Calculated grade: D+
Minor outstanding DR omissions:
Did not test 1680x1050, 1920x1080, 1920x1200, or Surround Gaming.
Summary of widescreen-related flaws:
Hack Solution
Could lead to possible server ban from online anti-cheat software.
