Apollo4x

Apollo4x is a single-player space strategy game built around transporting five resources between planets with limited fuel. You manage trade and upgrades turn by turn in a tycoon-style puzzle economy, while a spreading enemy threatens to consume the map. There are no competing players, ship fleets or build queues.

Trade between planets

Each planet has three exports and two imports. You earn money by matching one planet’s exports to another’s imports, while fuel availability limits how much you can transport. Fuel depends on each planet’s upgrade level, and every turn involves direct interaction with your economy rather than waiting through long build queues.

Contain the enemy

The enemy spreads organically from its homeworlds at a pace set by the difficulty settings. You must slow its expansion and defend your planets against the advancing threat. Each enemy colony adds one army to the defense of its homeworld, so pruning colonies can prevent the enemy from becoming too strong or expanding too quickly. If you choose to cleanse the galaxy entirely, you must first weaken the enemy through attrition.

Tactical ground combat

Combat uses a tactical card system involving morale, combined arms and a choice of tactics for distinct units each turn. Four enemy clans—Death, War, Pestilence and Famine—have different units and tactics, requiring different battle plans. War relies on brute force, Pestilence uses morale-crushing horror weapons, and Death has abandoned its bodies for machines, becoming a force of unliving reapers. There is no space combat or fleet building: troops are dropped in to fight on the ground.

Choose your victory

You can win by destroying every enemy homeworld, stockpiling 300 of each market resource, or upgrading your colonies to produce a cumulative 500 stellar network points and colonizing 20 planets. These are military, economic and expansion victory paths.

Set the difficulty

Difficulty is adjustable across the game’s economy and the enemy’s expansion. You can make the economy more demanding, weaken the enemy, give it fewer starting colonies or reduce its expansion rate. You can also make the economy easy while placing all four enemy types on the map at maximum strength, or turn off economic failure and use unlimited funds.
