About this game
About Tyrannis: Co-Prosperity
Tyrannis: Co-Prosperity shifts the fight of rebels against mercenaries to East Asia, where units of Freelancers fight to weaken the grip of the Security Division of the Kirihara Group.
Outnumbered and outgunned, their greatest strength is guerrilla tactics against the world's largest megacorporation and their allies.
Create your own faction and bring the fight to the corpos... or create your own security force and replace them as top dog in East Asia.
Gameplay
Tyrannis: Co-Prosperity's turn-based strategic gameplay pits armies of overstretched Security Forces against outnumbered Freelancers.
Through asymmetric gameplay, the Security Forces will run Search and Destroy missions to hopefully root out the Freelancers, while the Freelancers work to raid their enemies and liberate the country from the Security Forces' control.
Features
40 Unique Maps
Expanded Custom Faction Creator
Campaign With 3 Branching Paths
Earn Loot By Conquering & Raiding Districts Across Asiia
Campaign and Skirmish Integration
Campaign Mode
Create your own character and faction to fight against an army of mercenaries in a roguelike campaign across East Asia.
As you liberate more regions, you can further develop your own faction into a stronger, unique fighting force that can go toe-to-toe against Kirihara's Security Division.
There are 40 maps for you to liberate from corpo control, and the fate of East Asia is in your hands.
Will you burn the world's largest zaibatsu to the ground? Would you take it over and rule over its corporate empire? Or will you create a new balance in East Asia?
The choice is yours, Freelancer.

Christmas Cross-Content Update
So if you noticed that there have been about half a dozen updates in the last 24 hours, that's because I've been working on three things.The first two are the bugged Sri Lanka map and a glitch where menus wouldn't reset after exiting a loaded Skirmish. Both have been fixed.But the third, and the real reason I've had to push about half a dozen updates or so in the last day, is because I'm happy to announce a new mechanic for my games called Cross-Content.What Is Cross-Content?Cross-Content is an experimental feature I'm rolling out today where owning one cGh ONE game in your Steam Library will unlock additional content in other cGh ONE games.For example, if you own Tyrannis: Co-Prosperity or Infinite Voyager, Cross-Content would allow you to unlock additional maps in Tyrannis, and vice-versa.Also it wasn't my first pick for a name, but my that one was taken by an Adult Entertainment company, so that wasn't an option.How Does Cross-Content Work?Cross-Content works by having the files for two or more cGh ONE games installed in the same folder. When loading up a game, the game will automatically detect any other cGh ONE games and unlock the relevant Cross-Content in the game you're currently playing.For example, you'll want to have Steam save your files Tyrannis and Tyrannis: Co-Prosperity installed in the same location. Once you load up Tyrannis, the game will detect that Tyrannis: Co-Prosperity is installed. If Co-Prosperity is detected, an icon in the lower right-hand corner will be highlighted to indicate that the game is present in your library, which will unlock the relevant Cross-Content.Note that if you do not have Co-Prosperity, the icon will still appear but it will not be highlighted.Once the Cross-Content from Tyrannis: Co-Prosperity has been unlocked, you will be able to play with it in Tyrannis. In this case, that means all forty maps from Co-Prosperity can now be played in Tyrannis.Cross-Content in TyrannisBy owning and having Tyrannis: Co-Prosperity inst...Read full article on Community Announcements (cGh ONE)Patch NotesOfficial

September 15 Icon Patch
Hey, Chris here with a quick update. Just wanted to let you all know that the custom icons should look much better, now that they don't overlap.Yeah, that's about it. This game's pretty much done for now, but I'll update it if I run into any more glitches or bugs.Anyways, hope you all have a good one.-ChriscGh ONE's one guy who basically did this for Tyrannis as well, so that's why you might be reading the same message twice.Social MediaWeb: https://cghone.com/Bluesky: @cghone.bsky.socialYouTube: Discord: https://discord.gg/B5TEdTkEzkTwitter: No.Read full article on Community Announcements (cGh ONE)
