What the developers have to say:

Why Early Access?

“Mini Metro has been in open development since September 2013. We've had such a positive experience throughout the alpha that we decided to continue development in Early Access.”

Approximately how long will this game be in Early Access?

“We expect to release the full version in late 2015.”

How is the full version planned to differ from the Early Access version?

“We would like to add the following features and content throughout the Early Access period:

  • procedural audio by Disasterpeace
  • the unlockable Rush Hour mode, for the ultimate challenge
  • achievements
  • trading cards

You can see the full list of tasks, including plans for possible post-release features, on our Trello board.”

What is the current state of the Early Access version?

“Both the classic scored game and endless zen mode is fully playable in ten cities, with leaderboards for each.

We'll be adding the remaining functionality and content, tweaking game balance, and fixing bugs (not that we plan on adding any, but ... you know) every week or two.”

Will the game be priced differently during and after Early Access?

“Mini Metro will be available at a reduced price while it remains in Early Access. The base price after release will be $9.99.”

How are you planning on involving the Community in your development process?

“We have an active community that we stay in touch with through Twitter, Facebook, and our own discussion forums. The community has already helped us shape the design of Mini Metro through the alpha, and we plan on continuing that through Early Access and post-release.”

Upcoming price increase!

We've just pushed beta33 with a few tweaks to the audio and a number of stability fixes. As of beta31 we've been getting automatic exception reports through Unity Cloud Services, which is making it much simpler to find and fix all sorts of issues—wish I'd known about it months ago! :)

Now that the audio is in and a release date is looking closer, we'll soon be increasing the price of Mini Metro. The original intention, back in August 2014, was to steadily increase the price until launch as the planned features were added. The first increase was always going to be happen when audio went in ... seemed like a good idea back when we expected it in after only a few months.

So, if you're waiting to pick up Mini Metro, now's your chance! If you already do (thanks!), tell your friends to get in while the going's good. Preferably all of them, repeatedly. Just keep at it until they cave.

Beta31: Audio!

After more than a year in Early Access (how did that happen!?), audio is now in on the main branch. We hope you enjoy it! We're working on a few issues, and Disasterpeace is busy perfecting it, so there may be some changes over the next couple of weeks.

In other news, we've redesigned the city selection screen to show a city preview again, as well as a short description of what to expect from each city.

About This Game

In Mini Metro, you take on the task of designing the subway layout for a rapidly expanding city. Your city starts with three stations. Draw routes between these stations to connect them with subway lines. Commuters travel along your lines to get around the city as fast as they can. Each station can only hold a handful of waiting commuters so your subway network will need to be well-designed to avoid delays.

The city is growing. More stations are opening, and commuters are appearing faster. The demands on your network are ever-increasing. You'll be constantly redesigning your lines to maximise efficiency. The new assets you earn every week will help immensely — as long as they're used wisely.

Eventually your network will fail. Stations will open too quickly. Commuters will crowd the platforms. How long the city keeps moving is up to you.

Key Features

  • Compelling, constructive, hectic, relaxed gameplay. If that makes sense. It doesn't though, aye? You just gotta play it.
  • Three game modes: Normal for quick scored games, Endless for stress-free sandbox play, and Extreme for the ultimate challenge.
  • Eleven real-world cities to design subways for (London, New York City, Paris, Berlin, Hong Kong, Osaka, Saint Petersburg, Montreal, São Paulo, Cairo, and Auckland). Each has a unique colour theme, set of obstacles, and pace.
  • Random city growth, so each game plays out differently. A strategy that proved successful last game may not help you in the next.
  • Each game's map is a work of art, built by you in the classic abstract subway style of Harry Beck. If you think it's a keeper, save it, tweet it, show it off or make it your desktop background!
  • Soundtrack by Disasterpeace
  • Colorblind and night modes.
  • Trains! Did we mention them yet?

Demo

You can check out Mini Metro for yourself and play a game on the London map in the demo. The demo uses the Unity webplayer, so you'll need the Unity plugin (Windows and OS X only unfortunately).

Early Access Review
Mini Metro is an elegant subway management game from developer Dinosaur Polo Club. Game play, a matter of laying out subway routes in a growing metropolis, takes only minutes to grasp. Yet the emergent complexity of your task leads to hours of enjoyable and quite challenging play.

The genre of Mini Metro is hard to say. I’ve heard it called both a sim and a puzzle game. The truth is it has elements of both (as well as a feature or two I associate with arcade games): you are given a map of an urban area composed of stops your train lines must connect. Your job is to choose the routes for the lines as well as which lines to upgrade with extra train cars and which stops to build interchanges at. As you play more stops are added, putting a greater strain on your system. The game ends when one of your stations remains over-crowded for too long, crashing your system. For every week you successfully keep the transit grid running smoothly you’re rewarded with a few more resources: some extra tunnels, a new subway line, etc..

(Worth noting is that passengers are simulated individually. They are represented as shapes corresponding with the stations they want to arrive at. Thus it is easy to tell at a glance where things are going wrong. Unlike, say, Sim City, where an esoteric formula determines where businesses will flourish, the mechanics of MiniMetro’s simulation are overtly visible. I find this pleasing.)

All this sounds typical of a sim. But while Mini Metro definitely is about simulating the movements of passengers on a subway system, it stylized so as to focus solely on a design puzzle not on a recreation of reality in all its minutia. Money, scheduling, and staff are not part of the game at all. Construction is instantaneous. And if you choose to tear out a line and completely reroute it this can be done at any time at no penalty. Your task is simply to figure out how to lay out the pieces you’ve been given to deal with the ever increasing load.

This stylization shines in one of Mini Metro’s best features—its minimalist graphics. The entire game looks like one of those iconic London tube maps (originally designed by electrical draughtsman Harry Beck—hence the circuit-like abstracted clarity). Your “city” is composed of a general layout of bodies of water and brightly colored tube lines connecting geometric nodes. So confident are the creators of the resulting visual charm that screen capture is built into the game. The confidence is warranted.

Still in Beta at the moment, Mini Metro does have some rough edges. The most prominent is the complete absence of sound. (The developers assure that audio will be implemented any day.) More irksome is clumsiness in the interface. Rerouting lines where you’d like them is sometimes rather more difficult than the click and drag interface seems to warrant. Also, lines occasionally fail to properly bend to avoid water when it seems they should. But none of this was a significant obstacle to my enjoyment—especially as a pause button at least allowed me the time to do the needed fiddling. I still hope these wrinkles get ironed out, though.

Gameplay is fundamentally open ended. There is no point at which you’ve “solved” a city, rather you simply keep building until your system collapses. Nor is there any question of memorizing a working strategy for a given city: the stops one begins with, and the order in which they are subsequently added is randomized so that no two playthroughs are the same. This is where play felt arcade-like: even though your task is more typical of a sim or puzzler, your ultimate aim ends up being to beat your previous score, that is, to transport more Londoners (or Tokyoans, New Yorkers, etc.) than you managed to last time. It’s addicting. It’s difficult not to respond to a loss with the though “I can do better” and begin again.

To sum up, Mini Metro isn’t quite finished, but it’s already a really solid choice for people who want to grapple with a difficult design problem in a very attractive package.

I have to write a review, since the game finally received an audio update and I couldn't have wished for anything better. It makes the immersion just that much better and completely eliminates any need to put your own background music on.

The game is an overall total eye-candy. From the menus, transitions, to the actual game, it's so simple and colourful. Optional features include Night- and Colourblind modes, which are a great addition. There are also fast-forward and pause buttons, so you can get through the early slow start of the game quicker, and pause if you just want to relax or chat with friends, while having the game in the background. The only problem is that it's so addictively fun that you could find yourself neglecting your chat window more often, than the game itself.

Developers are also offering a demo version of the first map on their website.

Try it out for yourself, it's wonderful!

If I ran the tube like I ran my lines here, there would be triple the strikes.
