Game Card System

Coming soon

A visual, FlowGraph-powered, end-to-end card roguelike framework for Unity.

Unity 2021.3+ · Unity 6 recommended · Built-in and URP

Build complete card-battle content visually: author cards, decks, units, enemies, statuses, and encounters in the six-mode Game Card Editor, then create gameplay through FlowGraph instead of new C# classes.

Game Card System is built for teams that want to construct a full card roguelike visually, not just prototype a few cards. Six Game Card Editor modes cover cards, decks, player units, enemies, statuses, and encounters, while Game Card Monitor keeps live Play Mode battles inspectable.

FlowGraph is the gameplay layer. Cards, statuses, and enemies use embedded graphs made from 145 built-in nodes for damage, block, status rules, targeting, random choices, loops, hooks, events, VFX, and enemy intents, so large card libraries do not become large piles of one-off scripts.

  • Six Game Card Editor modes for cards, decks, player units, enemies, statuses, and encounters
  • 145 core FlowGraph nodes plus 2 Demo FX extensions for card effects, status rules, hooks, loops, selectors, events, VFX, and enemy intents
  • Game Card Monitor plus runtime battle state, hand/deck flow, event hooks, and GCSApi integration
  • Playable reference demo with 12 scenes, 4 classes, 80 cards, 16 decks, 12 player units, 16 enemies, and 30 statuses

Visual authoring

Create the whole battle content model in Game Card Editor: cards, decks, player units, enemies, statuses, encounters, and their databases, then inspect live battles in Game Card Monitor.

FlowGraph gameplay

Wire card effects, status rules, enemy intent patterns, hooks, loops, selectors, events, and presentation calls with 145 built-in nodes before writing custom code.

Playable reference

Use the included 12-scene demo as a concrete reference for classes, decks, normal encounters, elite fights, boss battles, statuses, enemies, and battle presentation.

Frequently asked questions

When does Game Card System release?

Game Card System is being submitted to the Unity Asset Store for review in July 2026. The public release date depends on official approval and will be announced on the website, Discord, and the blog after the review is complete.

What ships in the playable demo?

12 battle scenes across 4 classes, 80 cards, 16 decks, 12 player units, 16 enemies, 30 statuses, and 8 intent icons, all authored with the same Game Card Editor and FlowGraph tools you get.

Can I add custom nodes and content types?

Yes. Custom FlowGraph nodes subclass one of 7 authoring base classes, and card types, tags, and description tokens register through attributes. Battle state, events, and content discovery are all reachable through the documented GCSApi.

Does it depend on other assets?

No. The runtime has zero third-party dependencies.

Does it integrate with Game Event System?

Optionally. When both are installed, an optional bridge forwards GCS battle events into GES event channels. Neither asset requires the other.
