Guns of Icarus Alliance on Steam for free at the Humble Store

Guns of Icarus Alliance is the expanded and definitive edition of Muse’s flagship title Guns of Icarus Online, the original player-vs-player steampunk airship combat game. Alliance features all of the content from the original title, but with the addition of player-vs-environment cooperative experiences, an ongoing war between six elite factions vying for control of a world ravaged by machines, and an ever-changing world that is constantly being shaped and reshaped by the players. With a good ship and the right crew, you can conquer the skies - and maybe even the world! 

The ultimate co-op experience
Players can take on the roles of pilots, gunners and engineers, working together as a single unit to maximize their airship’s effectiveness and own the skies. You won’t be told to stay still and not die while a veteran preserves their Kill/Death ratio. In Guns of Icarus Alliance, you are forced to work together. It’s an entirely interdependent gameplay experience that cannot be won by a single crew member.

Your crew versus the world
Take your airship and crew, and pit them against a huge variety of AI-controlled challenges, including escort missions, convoy raids, base assaults, and more.

AI that learns
The AI won’t take defeat lying down. Dynamic learning systems mean that every battle will teach the AI what tactics you use, increasing the challenge with every fight.

Pit crew against crew
In addition to AI-controlled missions, airship crews can also battle one-on-one against other human-crewed opponents.

Every battle matters
Six rival factions are in a constant battle of wills to take and retain territory and control vital resources. Every victory and defeat will sway the tides of the larger war.

Become a legend
The story of Guns of Icarus Alliance is constantly being written based on the results of online gameplay. Achieve a key victory and your name may become part of the lore!
 

A vivid steampunk world
Lumbering, heavily-armored airships bristling with guns patrol the skies above a land ravaged beyond repair by an out-of-control industrial revolution.

Build your own airship
Starting from a selection of basic hulls, players can mix and match hundreds of custom parts to create their own unique airship, then assemble a crew to fly it.

Your ship is your life
Your ship is your collective life bar - when the ship goes down, the crew goes down with it. Every member of the crew plays an integral role in not only maintaining the integrity - “life” - of the ship, but also weakening the integrity of enemy ships as they work cooperatively towards a shared victory.
