What Ultra War is
Eight factions are fighting for the Galactic Core, and every one of them plays differently:
- Solari: radiant warriors and towering Ultrasaurs. The sun never yields.
- Hegemony: build a formation, reinforce it and advance as one. Order. Iron. Victory.
- Nereid: hide your threats and pull the battlefield beneath the waves.
- Fungus: adapt, integrate and turn the fallen into your next advantage.
- Synthari: run the Reactor hot, spend Energy to Surge and Overclock, and never let the Heat overload.
- Spacers: trade in secrets, smuggle an advantage and make your own rules.
- Veilborn: pay the price of forbidden power and bend the enemy to your will.
- Gobbos: cheap scrap, big ideas and bigger explosions. Probably safe. Definitely loud.
Five ways to play, one war
Ultra War is built in layers that feed each other, so time spent in one mode moves you forward in the rest.
Skirmish. Faction card battles are the heart of the game. Build a deck from your faction's cards and take on the computer, with a guided Campaign that teaches you the ropes.
A few of the cards you can build a deck from.
Dominion. Found a colony on a world of your own. Build it up, research, claim its moons and hold it against raids. Colony battles are real card battles fought with your deck. As of this week, the station in orbit over your colony can become your own harbour, collecting dues from the ships that dock there, even while you are away.
Busy harbours draw trade, and trouble. The Gobbos boomtown, from the loading screens.
Flagship. Fly your own Flagship in full 3D. Mine asteroid belts, trade at stations, hail traffic on the lanes, take contracts and fight pirates.
A Spacer corsair runs a chase through an asteroid field.
The Galactic Map. A persistent war for the Galactic Core across hundreds of systems. Commission Commanders and send them on sorties for your faction while you are offline.
The Synthari swarm front.
Your Star Captain. That is you: one level earned across every mode, plus gear, a service record and your standing with every faction.
What early access means
Ultra War is in alpha playtesting. The game is fully playable and it changes fast, sometimes with a dozen releases in a single day. Numbers get tuned, screens get rebuilt and now and then something breaks. Your progress is saved in your browser for now, with cloud saves on the way.
A Nereid fleet rises from the deep.
Galactic Credits, War Marks and the other currencies in Ultra War are in-game only. Nothing you earn or spend changes a deck, a card or a match, so card battles stay fair.
Help us build it
Every page of the game has a Report a bug button in the top bar. You don't need to sign in: say what happened and what you expected, and the report carries the page, the build and any recent errors to the team automatically. Reports we fix earn the Bug Hunter title, and player reports are already shaping the game.
To follow along, the Ultra War Devblog posts a daily digest of everything that shipped, plus longer looks at new systems and what is coming next. On the list right now: more ways to spend Galactic Credits in every mode, bigger Colony Stations, cloud saves and new faction ships.
For Cardania and Stellar Hood holders
If you have been with us since the Cardania days, Ultra War is where that community heads next. We are working on Ultra War perks for holders of our legacy Cardania and Stellar Hood collections, and we will share the details here when they are ready.
Enlist now
The war has started without you. Play the Ultra War alpha at ultrawar.io, choose your faction and tell us what you think. See you on the front, Star Captain.
