NPCs serve a number of purposes and appear in your large home, town, fortress, or base after certain requirements are met. There are 22 NPCs currently available in Terraria - the number varies depending on which platform you’re playing on, with the PC version being the most up-to-date. Learn all about Hardmode and pet Companion Cubes on the Terraria Portal Easter eggs guide. Many NPCs will only appear in Hardmode, and one NPC (the Cyborg) is your only ticket to getting the Portal Gun Station. Learn all the steps and triggers in the full list of currently available NPCs below. Naturally, we think it’s in your best interest to get them all - even Santa Claus. Instead of making things too complicated, here you’ll find simplified versions of instructions, with a little pertinent information to help you decide if these NPCs are worth the time.
