Operation: Midnight Meridian – A Tactical Submarine Web Game

What I Built

Operation: Midnight Meridian is a web-based tactical simulation that challenges players to manage submarine logistics and master complex code-breaking.

Set against the backdrop of the June Solstice, players must coordinate the deployment, supply lines, and encrypted communications of a nuclear submarine fleet during a critical global defense operation. The solstice timing plays a key role in the game's mechanics, affecting surface visibility and transmission windows. To succeed, you have to balance the harsh realities of military logistics with the mental agility required to decrypt intercepted enemy signals before time runs out.

How I Built It

I wanted to build a fast, responsive game directly for the web browser without relying on heavy game engines.

• The Tech Stack: The game is built using vanilla web technologies. I utilized Vite as my build tool (as you can see in the package.json) to keep the development environment incredibly fast and the final bundle lightweight.
• Mechanics: The core challenge was building a lightweight logic engine capable of tracking complex fleet logistics while simultaneously running the cryptographic puzzles. Balancing the macro-level global defense strategy with the micro-level code-breaking required a lot of state management tweaking.
• Design: By sticking to browser-native technologies, the UI feels crisp and immediate, resembling an actual tactical command terminal.

• Best Ode to Alan Turing: This game is a direct homage to Turing's legacy. The core progression relies heavily on cryptography and code-breaking under immense pressure. By tying the encryption puzzles directly to the survival and logistical success of the submarine fleet, the game highlights how vital mathematical decryption is to global defense operations.
