Since the original PC port of Chaos Legion (2003) is quite old, it natively supports only 4:3 aspect ratios (like 1024x768). To play in 1080p, 1440p, or 4K without the game looking stretched or "fat," you need to edit the game's configuration file manually.
The original Chaos Legion PC game was designed with a 4:3 aspect ratio in mind, which was the standard for monitors at the time of its release. However, with the advent of widescreen monitors and the increasing popularity of 16:9 and 16:10 aspect ratios, players sought a way to enjoy the game with a more immersive and cinematic experience. chaos legion pc widescreen fix
