About Mk48

Mk48 is the source repository for Mk48.io, an online multiplayer naval combat game in which players command a ship and sail to victory while avoiding torpedoes. The repository includes the game's client and server code, asset files, and instructions for building and running the game locally.

Developers can follow the build steps to produce a working game, which the repository notes could be used to host a private server. The repository also explains where entity types such as ships, weapons, aircraft, and obstacles are defined, and how entity textures are added to the spritesheet. The repository notes that its commits may lag behind game updates, so the code may not match the current live game. Pricing is unknown.
