A co-op horror run through a mansion, bathrooms and dungeon maps with monsters, loot, a shop, upgrades and simple objectives like trapdoors and final exits. The code wires a networked game loop with levels, a round timer, player controller and spectators, AI using a custom grid A* system, loot containers and inventory, map doors and triggers, and Razor UI for HUD, shop and effects. Audio, particles and post effects are driven client-side while the host runs authority for state and RPCs.
