Guide:Game progression graph

Terraria is a huge world which reveals its content to the players in discrete chunks. Unlocking additional parts of the game is often described as "Game Progression".

For a more detailed walk through of the game, try Guide:Walkthrough.

This guide is a graph that summarizes the bulk of the game as chunks with dependency lines ( '&#108;', '/', or '\') indicating mandatory steps to unlock them. Depending on the difficulty of the challenge, players may also have an implicit need to finish other (lateral) parts of the game before proceeding. The blocks below are color coded depending on whether they are a  Biome , Boss , Event, or Key Item or NPC.
