About Gargantua

Gargantua is a city-building and strategy game set across a dynamic universe of dozens of procedurally generated planets. You manage trade, production and defense aboard a massive spaceship that also serves as your city. Each session generates a new map, and every trade, journey and decision has consequences.

Trade and supply

Planets specialize in producing certain resources and demand others according to the time and circumstances. Prices shift with global supply, available raw materials and the difficulty of interplanetary logistics. You can hoard goods, monopolize products and manipulate prices for profit, but shortages can spread through supply chains, disrupting industries and causing wider crises. Unmet demands can also clog logistics chains.

Planets trade and go to war with one another. Selling weapons can strengthen one side, while trading with its opponent becomes more expensive. Clearing pirates from space can help revitalize the economy.

Build your strategy

Each time you level up, you choose whether to focus on production, defense or management, or pursue a balanced approach. Your economic choices directly shape your military strength: ammunition for defensive towers must be produced in your factories or purchased.

Defend your ship

Interplanetary travel exposes your ship to waves of enemies. You build defensive towers on its deck and keep them supplied with ammunition, balancing the needs of your economy against the demands of combat.
