Engine02 is a script-driven, multiplatform 2D game engine with builds for DOS, Windows, Linux, Intel/PPC MacOS, PSP, and Wii. Complete documentation for creating games is included with PC and Mac builds, and is also available on the website.

Games created or hosted by the author and his team are directly downloadable from inside the program. Updates for the program, or any installed game, can also be downloaded from the same interface when they become available.
