In Hephaestus, the player is given a varietyof play experiences. Customize your robot and form alliances to achieve your goals. Collect resources and use them as currency for services and other materials. Form a team among allies that you trust. Design and build structures that allow you to traverse and stake out land. Use pre-made equipment wisely and sparingly. Defend your land from opponents. Control the flow of lava on the planet to serve your own purposes.

As players design their robots, they wrestle with design trade-offs among several variables, including acceleration, top-speed, breaking ability, center of gravity, and torque). Each feature of the game world (weather, day / night, location) corresponds to a specific physics concept (friction, energy consumption, or center of gravity). The user scenarios illustrate how these design trade-offs play out in the game.

Part of the gameplay is designing robots to meet your design goals. These parts include:

  • solar panels
  • wheels
  • metals
  • chases
  • gearboxes
  • batteries
  • motors
  • axles


The specifics of these parts are being created and modeled by Woodie Flowers' group.

Players collect and trade energy sources through solar collectors, geothermal collectors, wind collectors, and mines. Thus the gameplay involves securing batteries, sunlight (solar), wind, lava flows, solid fuel, and vegetation and converting them to energy. Energy is stored and represented in batteries, coal (coal / mineral conversion become its own economy), and gold / money

Because robots must work together to achieve goals, Communications are a critical part of the game. Robots have antennas, and there is a cell phone like network of towers throughout the world.
