What Platinum Arts Sandbox is
Platinum Arts Sandbox is a free, open-source 3D game maker for building games, worlds, levels, adventures and quests. Creation can happen individually or cooperatively, with users editing worlds together over the internet or a LAN. The workflow is performed in-game and does not require compiling. Listed modes include cart, sidescroller, movie or machinima and RPG; the home page also references FPS Creator and Water Gun Wars. Height-map mode supports mountains and caves, and supplied maps include quests and other content. Users can import md2, md3, md5, iqm, smd and obj models, with popular sound formats supported. Maps export as .obj files for use in engines such as Unity. Downloads include project files for Visual Studio, Codeblocks, a Linux makefile and Xcode. The project targets Windows, Linux and macOS, though the listed 2.8.2 downloads are Windows and Linux editions dated January 19, 2013.
