Multiplayer roguelike dungeon crawler written in C# that runs entirely in the terminal, built for the Object-Oriented Design course at WUT. Up to 9 players connect to an authoritative server over TCP and explore a procedurally generated, hacker-themed dungeon together, collecting loot and fighting enemies that see and hear them. Almost every game system is built on a classic design pattern, from commands and strategies to decorators, builders and abstract factories, all rendered in a flicker-free, colored console UI.
