The War is Over, Pirate Week Begins!

The first war of Icarus ends. Long live the North!

The war ends with a begrudging surrender. The Northern Guard claims victory and an uneasy peace settles across the land. A peace that is more of a mask for the next insidious attacks from all the factions, piracy.

Those that don't accept the fight as over are taking to raiding and pillaging. Some are loyalists looking to fight for honor others are opportunists looking to take the post-war chaos to make a quick buck.

So hide in your safe territory and strike out and plunder the world. Do it for your faction, for your pocket, and for an exclusive title!

The faction that has the most successful attacks by the end of the mission will all earn the exclusive Pirate title. No need to hold the territory, just capture, plunder, and move on!

This will continue until the 30th when a new patch drops and new factions join in with even more content!

Guns of Icarus - Online vs Alliance FAQ

I’m confused. Why are there two Guns of Icarus games?
Guns of Icarus Online is our original game, released back in 2012. It is an online-only team-based PVP (player-vs-player) game in which players join the crews of multiplayer-controlled steampunk airships and have huge battles in the sky, from two-on-two skirmishes right up to epic four-a-side battles.
Guns of Icarus Alliance is our new game that’s only been out for a month! It was originally intended to be an expansion for the base game, pitched initially as an “adventure mode” that would introduce PVE (player-vs-environment) missions for players who weren’t interested in PVP. Early in development it became clear that our vision was much bigger than a humble expansion pack, so Alliance eventually became a new stand-alone game.

So has Alliance completely replaced Online?
Yes and no. Online still exists as a stand-alone game of pure PVP, but it is closely tied to Alliance. Players in both games can talk to each other, and in-game assets purchases and all Steam achievements are shared across both games. Online is still available to buy on Steam at a greatly discounted price.
However, anybody who buys Alliance gets Online free and can play all of the content from both games in a single package. Alliance offers the complete Guns of Icarus experience, including both PVP battles, PVE missions, and the dynamic online world that ties it all together. For those with no interest in PVE, Online will still be there to offer awesome PVP goodness.

Does this mean Online is a dead product?
Nope, Online is still a living game with a large install base and an active player population.
We won’t lie to you: Alliance is our new baby and we’re definitely focusing most of our attention on it, but a huge amount of content for this new game will be fed back into the original. We are always coming up with new content, including mysterious new factions armed with their own unique airships, weapons, and upgrades.
Many additions to Alliance will also expand Online, so even if you are only playing PVP and have no interest in new political powers invading the world, any ships and equipment brought into the game by these new factions will also be made available to you. Even better, you can join a faction and have an impact on the game world just by playing PVP, without spending a single cent upgrading to Alliance.
Essentially, even if you don’t buy Alliance, its existence will keep making Online bigger and better for our loyal players.

Is this some kind of scam or ripoff to squeeze more money out of your players?
Not at all. Anyone who is enjoying the original PVP action of Guns of Icarus Online can carry on enjoying it as long as they want to without sending us a single cent. We aren’t forcing anyone to buy anything they don’t want to, so if you’re happy with Online as it is, please keep on enjoying it.
Guns of Icarus Alliance was an enormous project that took us over three years to complete. This is not a map pack or a handful of new mission types: this is an entirely new way to play the game. We have added a dynamic and ever-changing online world that reacts to players’ victories and defeats, a living story that is being written week by week according to events in the game, an extremely complex AI system that makes the entire PVE experience possible, and so much more. It is a much bigger project than Online ever was.
We feel like we are charging a fair price for Alliance, and we have also sweetened the deal for existing players by offering a discounted price to upgrade until May 30th. We also offered some heavily-discounted pre-order deals during the development process, and players who got on board during the Kickstarter in 2013 also got a very good deal.
If you still think we’re ripping our players off then there probably isn’t anything else we could say to change your mind. Sorry we couldn’t convince you!

I backed Alliance during the Kickstarter or pre-ordered it. Where’s my copy?
If you one of the awesome people who supported the development of Alliance before release and registered your Steam ID with us, you should already have access to play Alliance. Visit the Alliance store page and you should see a notification saying “Guns of Icarus Alliance is already in your Steam library” and a “play now” button. If you don’t see this message, then something has gone wrong. We’re sorry! Please email feedback@musegames.com and we’ll get it fixed for you ASAP!

About This Game

Guns of Icarus Alliance is the ultimate cooperative gaming experience, uniting teams of players as the crews of gigantic steam-powered airships.
  • 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.
  • 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.
  • 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

    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!

Guns of Icarus Alliance is the expanded and definitive edition of Guns of Icarus Online, the original player-vs-player airship combat game. This new edition includes all of the content from the original game, so new players need only buy Guns of Icarus Alliance to enjoy everything the game has to offer. Owners of the original Guns of Icarus Online can upgrade to this new version with a 25% discount until May 30th.

The Industrial Revolution never ended. Raging out of control, the new machines consumed the world, staining the sky, scouring the land and poisoning the water. Humanity came the brink of extinction, all but destroyed by their own unrestrained ingenuity. A few pockets of civilization survived, sheltering in the crevices of the world, and it is time for a comeback.
Divided by wide expanses of toxic wasteland, a handful of these remnants have developed airship technology. Cruising through the sky, safely away from the poisoned earth, trade and industry could finally begin anew. However, with resources so desperately limited, war was inevitable.

After years of isolation, the four factions have developed very different ideas about how this new world should be reclaimed.

The Fjord Baronies believe that faith is the answer, and advocate sharply-defined social strata and humble obedience. With authority granted to them through a divine contract known as The Creed, the Baronites are overcoming their reluctance to make war in the knowledge that the realms they conquer are theirs by divine right.

The Order of Chaladon have appointed themselves healers of a mortally wounded world. The artefacts of the Old World are to be rejected, as it was the blind ambition and hubris of the Ancients that caused the world such grievous harm. Humanity must forge a new path, living in harmony with the earth so that it may heal, and the other factions must either accept this wisdom or perish.

The Mercantile Guild has no time for philosophy or religion when there is money to be made. These wealthy traders value nothing but wealth and demand the freedom to pursue it, unrestrained by petty concerns like morality. Of course, not every acquisition can be achieved through negotiation alone, and a well-armed airship is a powerful bargaining tool.

The Anglean Republic from the frozen north know that the future for humanity lies in its past. Entombed beneath the ice there are powerful relics of The Ancients, the people of the Old World who lived in the Golden Age before the earth died. What better way to honor this vanished civilization than to remake the new world in its image?
These are the four great powers that are currently known, but rumors abound of other nations secreted in remote strongholds, biding their time and gathering their strength. Who knows what the future may hold?

Select your faction, build a custom airship, assemble a trusty crew and get ready to change the world!
Every mission you undertake, whether it results in victory or defeat, will have an effect on the factional struggle for dominance. Play the way you want to: become a berserker who lusts only for battle and conquest, protect your domain from aggressive invaders, or take on one of your faction’s constantly changing list of objectives.
Missions take a wide variety of forms, including straight-up airship battles, tense infiltrations, convoy raids, assaults on heavily-fortified bases and much more. Impress your faction and you will enjoy great rewards, from unique character costumes to powerful experimental weapons.
The story of Guns of Icarus Alliance is constantly being written, and in-game events determine the course of the story. This means that a player who achieves a key victory, oversees a notorious massacre or repulses an overwhelming invasion may find that their name becomes part of the official lore.
