​​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.

​​Machine Zone’s Gabe Leydon on why he cares about more players’ time than their money​​

​​July 25, 2013

Few people in the mobile game world are more passionate or outspoken than Gabe Leydon. So if the founder and CEO of Machine Zone (previously Addmired) has been quiet recently, it’s with good reason. He’s been working on a new game.

“It ended up being much more than I thought it would be,” he says of the 16 month development of Game of War: Fire Age. “It took on a life of its own.”

​​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.

    I have been working at Machine Zone full-time for less than a year


    Great fast paced environment and perfect for individuals seeking an entry into the gaming industry or for people who want to further establish themselves in their respective fields. Amazing team comprised of talented, passionate and competent individuals who are among the best at what they do. They are fun to work with and it is a pleasure to watch them work. New office is extremely spacious eliminating cramped work spaces and providing ample room for movement.


    This isn't really a con but it's fast paced company that requires complete commitment. If you snooze you lose.

    Anonymous Employee
    Anonymous Employee
    Application Details

    I applied online. The process took a day - interviewed at Machine Zone in June 2014.

    Interview Details

    I applied to this position because the job description stated that it was full-time with benefits. But on the phone interview, the recruiter told me that the position was contract. The interviewer told me that it was a contract position because that was the industry standard. Google didn't become the great company they are today because they only did things that were industry standard. Advice to hiring manager, please don't lie, it only makes your company look weak.

    Interview Questions
    • The recruiter only asked me if I knew JIRA, which was clearly stated on my resume.   Answer Question
    No Offer
    Negative Experience
    Easy Interview
