Carnage3D is an open source remake of the first Grand Theft Auto, built for the browser with Emscripten. The project calls itself very early stage. The original Grand Theft Auto came out in 1997 from DMA Design for MS-DOS and Windows. It is a top-down game in which you earn points through missions in three cities.
