The consistently high-performing Game of War – Fire Age reached #1 for the first time in worldwide iOS revenue in October. The game has seen success in multiple markets, including the United States, United Kingdom and Japan. Its performance in Japan is particularly worth noting, as it is rare to see non-Japanese game publishers rank so highly.

One Nerd to Rule Them All


March 05, 2015

"Machine Zone has 300 employees, most of them in Palo Alto. Seated at a long conference table, Leydon, 35, looks cheerful if a little haggard, riding on three hours of sleep, working a heavy layer of stubble, and wearing the usual Zuckerberg-style hoodie. The office is the size of a warehouse, and in one dimly lit alcove, Leydon has stashed a relic from his past. It’s a coin-operated single-shooter arcade game from 2007 called America’s Army."

Mobile Gaming has its Super Bowl Moment


February 02, 2015

"Most mobile games are free to play. And more than 100 million people in the United States already do. But it’s just a small percentage of players willing to make in-app purchases that enable the top games to generate more than $1 million a day. That’s the business model. And it’s working."

​​Insider Q&A: Machine Zone’s Gabriel Leydon​​

​​August 06, 2013

What’s it like to rule the world?

That’s the question Game of War: Fire Age attempts to answer, as players build kingdoms and align with mobile gamers from across the globe in order to make the most dominant iOS empires possible.

And while the storyline might sound familiar in the free-to-play, realm-building MMO space, the innovation here lies in the translation.

While other games separate servers and players by region, Machine Zone’s Game of War actually translates real-time text into 32 languages, enabling people from all over the world to not only play together, but to communicate freely in their own language, while the game translates the text so everybody understands the plan of attack.

​​Game of War: Fire Age is the MMO you have time for​​

​​July 25, 2013

The problem with MMOs is that I never have time to play them. Like long-term relationships, it’s a commitment. Players have to invest several hours each day in front of a computer to chat with friends, gain experience points and go adventuring. It’s almost like leading a second life and that can be hard to keep up when you’re already struggling with the first one.

But there is a way to distill the best parts of the MMO — the social features, the community, addictive gameplay — and it seems as though Machine Zone has figured it out. The early iOS developer has been working on an MMO for iPhone and iPad for the past 19 months, and today, it’s going live in the U.S. You can download it here.

​​Machine Zone launches ambitious iOS title Game of War: Fire Age after huge investment​​

​​July 25, 2013

After more than a year of effort on its biggest game yet, Machine Zone is launching its free-to-play Game of War: Fire Age today on Apple’s iOS platform. Among the features is an automatic translation engine that allows players from different countries to communicate and band together in alliances. That enables global gameplay and a chance for one player to literally rule the world.

Everything is built to facilitate mass battles with an unlimited number of participants fighting in real time. Players can team up in alliances of 100 people and attach their alliance to a kingdom. Different kingdoms can vie for the throne, and the winner can be crowned the king of the entire game. Hundreds of thousands of players can gather in the same space in the massively multiplayer online role-playing mobile game, the company estimates.

​​A Year In The Making, Machine Zone Launches Game of War, An Impressively Large MMO For iOS​​

​​July 25, 2013

While iOS games started out as either simple physics or casual simulation titles when the platform launched about five years ago, the bar has gotten steadily higher and more hard-core. Midcore studios like Kabam started to rise in prominence.

Now the iOS platform might be seeing is most hardcore title to date — a very, very massive multi-player title from YC- and Menlo Ventures-backed Machine Zone.

The company, which started out doing text-based RPGs a couple years ago like iMob, is launching Game of War: Fire Age. It’s a title where players build and grow empires, train massive armies, forge alliances with other players to win kingdoms.

​​Hardcore MMOG Game of War launches on iOS; gives you the chance to be King of Kings​​

​​July 25, 2013

Just released for iOS, the free-to-play title is a hardcore MMOG, which relies heavily on its social alliance structure. And that’s how the ‘god’ element comes into play. Each alliance has a kingdom, with a wondrous capital building, and every kingdom needs a king to ruler over it. The king of each alliance has powers over their players in terms of setting taxes and giving individuals buff/debuffs as s/he sees fit. Of course, in keeping with how hierarchies work, the king of each alliance also competes upwards to become the King of Kings i.e. the overall ruler of the entire game.

    Anonymous Interview Candidate in Palo Alto, CA
    No Offer
    Negative Experience
    Easy Interview


    I applied through a recruiter. The process took 1 day. I interviewed at Machine Zone (Palo Alto, CA).


    Contacted by recruiter. Attended 4+1 rounds of interviews. Interview was easy and I was quite positive about selection but they didn't respond to me even after my request for result for about a week. I didn't like the fact that they took this much time in telling the result & on top of that they didn't even tell the reason for rejection. I would suggest to convey salary expectation from the beginning instead of wasting time in interview process.
