Fibonex

About the Game

Turn numbers into firepower

Fibonex is a single-player factory-building and tower-defense game where your production line is also your ammunition supply. Mine numbers, route them along conveyor belts and combine them in Math Machines. Feed the results into Ammo Makers, supply your towers and protect the Core.

Build a factory that can fight

The right number is part of the defense. When a wave calls for different ammunition, your factory needs to deliver it. Change a calculation, split a supply line or expand production to keep more towers supplied. A powerful weapon still needs a working route from the source to its input.

Research new tools, upgrade machines and bring different tower roles into your defense. Balance production and transport as enemies approach from different sides. Use the preparation time between waves to rebuild, or start the next wave when you are ready.

Reach the boss, then choose what comes next

Math Wars begins with a guided introduction and a compact sequence of goals leading through ten introductory waves to the first boss. New enemy types ask you to rethink your setup along the way.

After the first boss, finish your run or continue with the same factory in Endless. If a wave goes wrong, the saved preparation checkpoint lets you retry with time to adjust your defenses.

Make room for experiments

Sandbox opens the building and research toolbox for free construction and upgrades. Play with or without enemies, explore projectile and light systems, or work on a factory at your own pace. Six optional experiment ideas give you small goals, from making a seven to keeping both Splitter outputs moving.

• Choose industrial artwork or mathematical diagrams.
  
• Look up machines, their inputs and practical tips in the illustrated Block Wiki.
  
• Play locally with mouse and keyboard, save your factory and return to it later.
  
• English and German interface. Math Wars and Sandbox are included, with no in-game purchases.
