Questions
Is this StarCraft?
Buildcraft is a port and re-skin of StarCraft: Brood War. It uses Brood War's rules, units, stats, build times, ranges and balance, but all factions, names, art and story are original. It is a fan project, not Blizzard's game.
Is it free?
Yes. Buildcraft runs in the browser and costs nothing to play.
Is multiplayer available?
Not yet. The first build is a skirmish against the built-in AI in the browser. Multiplayer comes last.
How is it built?
It is built by a solo developer. AI coding agents write the code, and an AI-driven Blender pipeline bakes 3D models to 2D sprites. No Blizzard code, data or art is used, and all AI use is disclosed.
