Developer Ported 20-Year-Old Game 'GunZ' to the Browser

A developer ported the 2003 TPS GunZ: The Duel to run in browsers using WebAssembly and WebGL.

They kept most of the original C++ code and added a d3d9-webgl wrapper to translate Direct3D calls into WebGL.

They replaced Windows-only systems with browser standards and reduced asset size by 88% via audio reformatting.

The developer said AI tools wrote about 99% of the new code, using Google Antigravity and Claude Code.

The playable port is available online at gunz.sigr.io and the Velog post drew community attention.
