Terraria 1.4.5 Bigger and Boulder Update Released

ReLogic released the highly anticipated Bigger and Boulder update for Terraria on January 27, 2026, marking the game's first major content expansion in nearly six years and arriving simultaneously across all platforms, including PC, consoles, mobile devices, and Nintendo Switch. The free patch, version 1.4.5, introduces a wealth of new items, mechanics, and crossover elements from Palworld and Dead Cells, while enhancing core systems to cap off the sandbox adventure's long development history.

The update builds on Terraria's foundation as a 2D survival crafting game, expanding its already vast catalog to include more than 5,000 items, 400 enemies, and 25 non-player characters. Key additions feature 15 new furniture sets, five boulder variants such as a rainbow boulder and a pet boulder, four transformation mounts, new whips, kites, summoner prefixes, critters, and decorative pieces. Players can now experiment with a revamped world seed system, including a Skyblock option that generates an isolated island in the sky for challenging base-building, and over 100 seed combinations for unique worlds, like those turning players into vampires or replacing oceans with alternative liquids.
