Infinifrag 2 or Infinifrag II: Revenge of the Blocks was an unfinished multiplayer sandbox game developed by Zach Barth and Dan Hathaway. Conceived as a sequel to Barth’s earlier prototype Infinifrag, they intended to build on the idea of block based 3D worlds and combine it with mining gameplay inspired by the flash game Motherload. The developers envisioned opposing teams gathering resources, constructing structures, and engaging in combat, with influences from contemporary multiplayer shooters such as Team Fortress 2. The project grew in scope over approximately a year of development. Ultimately, Barth stepped away due to the increasing complexity of the design. Hathaway continued experimenting with the codebase after the collaboration ended, reworking many of its ideas into a first-person shooter project titled Block Arena, which would eventually get reworked again into Fractal Block World. Barth later released Infiniminer, whose more focused design would go on to directly influence Minecraft, making Infiniminer 2 an important but largely unseen precursor in the history of voxel-based games.
