Hollow Orbits 4X combines 4X strategy with the mechanics of a board game. Collect and use tactic cards, and roll dice for your fleet’s weapons. Play solo, against AI, or with friends for dominance in a galaxy filled with ancient dangers and hidden treasures.

Plan your shots

Roll a die for every cannon, missile launcher, or laser in your fleet. Dice can miss, hit, or trigger special effects — but the roll is only half the decision. You choose which enemy ships to target with each result.

Fleet formation matters. Ships in the backline are protected until the front lanes are engaged, unless you use long-range Precise weapons to bypass the formation.

Design your Fleet

Design a template and build it into anything from a Scout to a Titan. Create glass cannons packed with missiles, armoured tanks, missile boats, or long-range artillery. Weapons that gut capital ships can be useless against light screens. There is no perfect build — only a bet on what you expect to face.

A Galaxy Worth Poking

Send your scouts ahead to discover valuable planets and anomalies to investigate.

The richest worlds lie deep within the galaxy, but reaching them means reading the terrain and taking risks.

Asteroid belts and debris reward whoever arrives first. Ion storms slow movement and disable shields. Gravity wells pull ships inward. Wormholes can throw you across the galaxy without revealing their destination.

Every decision matters

• Build fleets around your own designs — from disposable missile screens to heavily armoured capital ships.

• Explore a procedurally generated galaxy where terrain, hidden routes and hostile encounters change every game.

• Fight over the inner galaxy, where richer worlds offer greater rewards and greater risks.

• Commit to a research path and shape what your empire can build — without retroactively upgrading ships already in the field.

• Plan simultaneously with your opponent, then watch both strategies unfold at once.

• Use fog of war, terrain and deception to hide your intentions and catch enemy fleets off guard.

• Every battle is a tactical puzzle: weapon matchups, defensive dice, terrain and fleet composition all matter.

• Play against four AI difficulties or challenge players online in 1v1 or skirmish up to 8 players.
