Welcome to the SectorCMD devlog. This is where we will share development progress, explain changes, and keep a record of each update.

The current alpha

SectorCMD brings real-time world conquest to your browser. Build your forces, capture strategic buildings, and take the fight from land to sea.

• Territory control and income.
• Land forces and naval operations on the world map.
• A multiplayer alpha you can play directly in your browser.

Tech Stack

• SectorCMD is built using TypeScript.
• Colyseus is the multiplayer/networking framework.
• 3D Game client is rendered with Babylon.js
• The RTS simulation, unit movement, combat, production, economy, territory control, AI, pathfinding, transports and game rules is custom SectorCMD code that runs along side the frameworks above.
• Node.js multiplayer server is authoritative, which means gameplay decisions are validated and simulated server side.

What comes next

Future entries will cover new features, balance changes, and bug fixes as development continues. Check back here for the next update.
