Terraria

Terraria is a 2D sandbox action-adventure game with platforming and role-playing elements. Players create a character and are transported into a procedurally generated world where they mine resources, craft equipment, build structures, and battle enemies. Progress is driven by defeating bosses, which unlock new levels featuring items, biomes, and challenges. The game features a class system based on equipped gear, as well as the recruitment of NPCs tied to achievements, and supports both single-player and multiplayer modes. Terraria also offers official modding support via the tModLoader framework.
