Monochrono Development Blog: AI (Part 1)

So, I’ve been hard at work on Monochrono™ basically ever since getting back from E3 (what an amazing experience that was. I might write more about that in a separate blog post, maybe on my Tumblr,) because everyone I spoke to about the game seemed super excited about it, including representatives from all three console platform holders. I basically came back, stretched, and got back to work with a renewed vigor.

The smart thing would be to work on art and animation on the title, but that’s the part of the project that’s a slog for me since it takes me so much time and I almost universally end up unhappy with it. The game design is actually almost finished, too, in a really cool way! I have on paper the exact design of the finished product that I hope to put out in 2017. So that leaves coding – specifically, a lot of the AI behind the scenes.


Monochrono’s AI works in an interesting way. I want it to feel human – by that I mean, I want it to be able to learn what you do and how you play, adapt to it in real time, and provide you with a challenging AI that challenges you as a player specifically, like playing against humans might. Learning to read your tells, learning to adapt to cover its own weaknesses – such that the player cannot coast on one strategy throughout the entire game (in Story Mode. Other modes feature different AI designs, but I’m not talking about those right now.)

Initially this led to a trial where I put very few restrictions on the AI and its abilities – I gave it starting abilities, and I told it to make itself stronger as it saw fit (essentially.) What that led to in practice was I completed an early stage no problem, and then the next stage, where it would adapt, the AI gave itself every weapon and power-up in the entire game, including 10 1-second invincibility weapons. Because I have the AI middleware from I’ve Got to Run! implemented, wherein it tests stages and layouts to make sure that it’s playable, it completely broke down and crashed the game before I could even attach a debugger. I had to retry it and set the process speed to 1/1000th so I could see what it was doing at a sub-frame level.


Clearly that sent me back to the drawing board – I couldn’t just make AI without restrictions, but I do not want players seeing the mechanisms at play. I want the game and its challenge to feel completely organic in every way. I also want to be able to play the game as a creator and experience a similar level of strategic requirement as a player playing it through casually on launch day.


I’ll share more about what I came across and decided on in a future blog post (largely because I’m still implementing it and if it goes terribly wrong, I want to do a postmortem on that, too.)

I don’t think blog posts on the topic of the game are going to always be in this postmortem format – I’ll probably just use this as a way to get across thoughts on the game and its development on a regular basis.


Finally, before I sign off, some bullet points!

  • Thank you to everyone for their kind words during and after E3. I was terrified to reveal the game after two years of working on it in silence, so to get a generally positive reaction in response was extremely heartening.
  • I made a booboo with my E3 trailers. I had made three trailers for contractual reasons – a trailer with an Xbox One endslate, a trailer with an endslate without listing platforms (that had PS4, PS3, Vita, and Wii U in the video title,) and then a Platform Agnostic trailer, that ended up with the announcement of Monochrono Prologue. Clearly that’s the one I wanted people to focus on, but…YouTube auto scheduling uploaded the PS4/PS3/Vita/Wii U trailer 30 minutes early…so that was the first trailer, thus the trailer that got all the retweets and news posts. Outlets got confused, too! My apologies. Game is coming to all platforms.
  • Monochrono Prologue’s Chapter 2 update failed Apple certification for containing inappropriate material that they don’t want on the App Store, which is fair. I’m working on a different version of that chapter, which will sadly delay it slightly.
  • Monochrono Prologue is STILL COMING OUT TO ANDROID. I’m just having a tough time developing for the platform without any device to test it on, and emulators are only so helpful. Please look forward to it.
  • Finally, question of the month! Please tweet @Monochrono on Twitter (or @MonochronoJP if you speak Japanese!) with the answer to the question: Would you like to see in-progress builds be streamed on Twitch throughout development? Please be honest with your answer (as in, would you watch live or as a VOD, not just ‘would you like to have the option to see it,’ and include the hashtag #MonoQ. I look forward to your response!


Thank you all so much for your support! Happy gaming!

Why Monochrono Prologue Exists

Hey! Going to be a bit informal here in my first of hopefully many blogs on this site, which will cover Monochrono™ development,

When I said back in early April I had one title (aimed at 3DS at the time) that would be releasing in June, the title was what would become Monochrono™ Prologue. First let me provide a quick rundown of the app, available now on the iOS App Store (iPad support forthcoming) and coming soon on the Google Play store for Android.

  • Monochrono™ Prologue provides the backstory to the protagonist of the upcoming arcade shooter game Monochrono™.
  • Monochrono™ Prologue is an Episodic Book, whereby content will be added on a regular (biweekly-ish) basis until the story is complete. The app launched with one chapter, with more coming every few weeks alongside larger app updates. The stories will not be told in chronological order.
  • The story is one that readers will need to stick with to get the full understanding of – readers will also notice an evolution of the app over time, including music, artwork, and more features not in at launch
    • To stress: the fact that these features are not in at launch was a conscious design decision, not due to constraints or rushing. It is a decision to better match what I am going for with the title.
    • One feature that will be coming soon that is not available at launch due to constraints is localization. The goal will be to support at least English, French, and Japanese by the end of the story.
  • Monochrono™ has a significant enough story to justify the app – as well as one other major reason. The story present in Monochrono™ Prologue, if present in the base game, would raise the game from an (anticipated) ESRB of T to an M. In order to widen the accessibility of the core title, and to not compromise on the initial vision, the story is being told in a different way.
  • The story will be told over the course of a few months and out of order – additional features such as reading the entire story chronologically (recommended to be done after finishing in “director’s cut order”) will be made available following the completion of the story.

So I guess that’s the bullet point list. But why do this, right? Why does Monochrono™ even need a story in the first place? And why do I keep adding the trademark symbol? You the reader GET it already.

…yeah I know. Just protecting the brand.

Monochrono™ has a story because it’s important to me. The story of Monochrono follows a character (whose name and backstory will be announced through Prologue) after their death, and follows my own internal questions about human consciousness and what that means in life.

As stated previously Prologue exists as its own product largely to possess a separate age rating. You don’t have to play Prologue to enjoy Monochrono™, but you will get more out of the story if you understand the character’s background and what they’ve gone through.

One thing to note that will make little sense now (or worse, just come off as needlessly pretentious,) is that Monochrono™‘s color scheme leverages heavy use of black, white, and gray. Prologue is exclusively black and darker shades of gray (with the exception of text display, which for readability is white.) This will make more sense in the future, and does not simply refer to morals or “darkness of tone or character.”


So, to briefly summarize, Prologue is an experimental way of telling a story that is personal to me. Huge parts of it are derived directly from personal experience, and most of the rest come from the experiences of my loved ones and those close to me. Every character in Prologue, regardless of their actions, is neither good nor bad, but the gray inhabit a gray space in between the two.


…and hey. If for no other reason, readers of Prologue will receive a bonus in Monochrono™.


Thanks for reading, and game (read?) on!

P.S. The app is launching at $0.99 USD, will increase to $1.99 USD after a significant amount of story has been added, and will settle at $2.99 when the story is complete and the app is finished adding content. Make of that what you will.

P.P.S. It’s not on Nintendo 3DS and New Nintendo 3DS currently because there are technical limitations in telling the updated story that I wanted to tell, but the versions are still planned when the story is complete (albeit at an admittedly lower priority, with Monochrono™ proper taking top priority. I would like to personally apologize to Nintendo 3DS players, who supported my previous release of I’ve Got to Run: Complete Edition!, for not delivering the Nintendo 3DS version in line with the mobile versions.

4 Corner Games Formally Announces Monochrono™ Prologue, now available

MADISON, Wisc. – In conjunction with the announcement of Monochrono, a multiplatform twinstick shooter releasing in 2017, which was announced at E3 2016, 4 Corner Games is also excited to announce Monochrono Prologue, available now on the App Store for iPhone, iPod Touch, and iPad.

Monochrono Prologue tells the backstory behind Monochrono in an ever evolving state. At launch, the story and app are both almost as barebones as it can get, with only one chapter of the story being available to players. More stories and features will be added in as the app evolves, changing the scope of the app, the appearance, and with it, the nature of the story.

More details are available on the official 4 Corner Games website at, and will be coming soon. The only way to experience the full story in the context of the evolving app is to begin reading and follow along with the app as it grows, so fans should not delay! The app can be found on the App Store, and is coming soon to the Google Play store for Android-based mobile devices.

4 Corner Games Formally Announces Monochrono™, the Upcoming Time-Bending Shooter, for a 2017 Release

MADISON, Wisc. – After two years in development, 4 Corner Games is slowly (and quickly, and slowly again) lifting the veil on Monochrono, the fast-paced time-manipulation shooter coming to PlayStation®4, PlayStation®3, PlayStation®Vita, Wii U™, Windows PC, Mac, Linux, and Xbox One, the all-in-one games and entertainment system from Microsoft, in addition to other platforms.

Monochrono is a twin-stick shooter broken into ten second chunks, with hundreds of independently intelligent enemies on screen and a clear mission. Players can, at any point, hold down a button to slow down time in the world by a factor of three, providing the essential hook of the game: players can strategize, position themselves appropriately, and release the button to hit their enemies. Because the player them self is not slowed down by the mechanic, it provides an essential layer of strategy that the game is built around.

When players play Monochrono upon its 2017 release, they will find themselves presented with many options and gameplay modes, including a fully fleshed out story campaign, an endless survival mode, a challenge mode with a stricter mission structure that sees players attempting to clear a challenge while completing three distinctly designed challenges, a local multiplayer mode, and many more unannounced features, modes, and unlockables.

The announcement of the title is just the beginning. Fans can stay tuned to, as well as follow @4CornerGames and @Monochrono on Twitter to stay in touch about the game’s development, including frequent developer blogs, screenshots, updates, and more. Direct gameplay footage as well as more feature announcements will be coming within the upcoming weeks, and those interested in the title will not want to miss it!

4 Corner Games Announces FY2016 Lineup

April 2, 2016 – Madison, WI

4 Corner Games LLC today announced details of its upcoming slate of games to release over the next fiscal year ending in March 31, 2017. 4 Corner Games, who last released I’ve Got to Run™: Complete Edition! on the Nintendo 3DS™ eShop on November 13, 2014 in North America, is thrilled to share the results of its hard work over the coming year.

First, fans can expect an update to the title I’ve Got to Run™: Complete Edition! in late April that adds new content to the popular handheld platformer. While the nature of the update is under wraps for right now, fans won’t have to wait long to experience it – the free update will be delivered in North American regions by the end of this month.

When Platform Arcade VR (Internal Codename, not reflective of production title) launches next spring, players with an Oculus Rift virtual reality headset or PlayStation®VR headset and compatible hardware will be able to immerse themselves in a digital sphere with classic-style arcade games taking place all around them, guiding them with a compatible gamepad controller while looking around not only at the playable characters or objects and their movements, but also at the entire map, granting players the unique ability to see the entire game field in full spherical form, presenting unparalleled strategy in the featured fast-paced games.

Platform Arcade VR (Internal Codename) represents over a year and a half of research and development into unique ways to utilize virtual reality headsets without simply changing control of the camera. Immersion is immediate, and every new experience in the in-game arcade can be immediately picked-up, understood, and enjoyed by a wide variety of players.

Platform Arcade VR is best experienced seated in a chair that can spin around 360º, and is expected to retail at $9.99

4 Corner Games also plans to ship an unannounced title for Nintendo 3DS and New Nintendo 3DS systems in June 2016. More details will be available at a later date.

Fans can also look forward to more information on Monochrono™, the first title in the “4 Corners Series”, at this year’s Electronic Entertainment Expo. Monochrono™ represents the most ambitious project that 4 Corner Games has worked on to date, boasting over 40 hours of unique engaging content, including a full story-based campaign mode. More details will be announced in June.
