After a long wait and plenty of teasing, Terraria 1.4.5: Bigger And Boulder is officially out now, bringing one of the biggest and most ambitious updates the game has seen in years. The update marks the start of Terraria’s 15th anniversary celebrations, and it lands with a clear goal, make the game smoother to play, richer to explore, and far more surprising than before.
If you have spent hundreds of hours digging, building, and fighting bosses already, this update is aimed squarely at you. Bigger And Boulder expands core systems, adds huge crossover content, and quietly reshapes how Terraria feels from minute to minute.
A Mostly Global Launch, With One Exception
Re-Logic has rolled out Terraria 1.4.5 simultaneously on PC, console, and mobile across most regions. The only version not launching today is the bespoke China mobile edition.
According to the developers, the Chinese mobile build relies on official online servers, which means the full 1.4.5 code needs additional server migration, review, and internal testing before release. With the update finishing close to the Chinese New Year period, the teams at Re-Logic, 505 Games, and XD agreed that delaying was better than shipping something unfinished. The studio says the China mobile update is coming as soon as possible once everything is ready.
Bigger And Boulder Is About Expanding What Already Works
The name Bigger And Boulder is not just a joke, though there are indeed new boulders to worry about. The update focuses heavily on expanding existing systems rather than simply piling on content.
Replayability has been boosted through improved world seeds, crafting and inventory management have been reworked to reduce friction, and atmosphere has received a noticeable upgrade through new effects, visuals, and music. It is the kind of update that quietly makes everything feel better while still sneaking in plenty of new toys.
Crafting And Inventory Finally Get A Major Overhaul
One of the most impactful changes is the new crafting interface. With more than 6,000 items now in the game, the old grid system was showing its age.
Crafting menus are now organised by clear tabs such as weapons and furniture, fully searchable, and styled similarly to Journey Mode’s research system. Players who prefer the old list view can still toggle it back, but the new interface makes finding recipes dramatically faster.
Crafting from nearby chests has also been improved. Materials can now be pulled automatically from storage without opening chests or moving items into your inventory first. For players with well-built bases, crafting is now almost frictionless.
Inventory management also gets welcome quality of life upgrades. Identical items now stack fully, even with matching prefixes, and banners no longer need to clog up storage. A new banner menu lets you claim and apply bonuses when you want, without carrying them around.
A New Spectator Feature Changes Multiplayer Deaths
Dying in multiplayer no longer means staring at a respawn timer. The new Spectate feature allows dead players to cycle through teammates’ perspectives while waiting to respawn.
It is a small change that adds a lot of energy to boss fights and multiplayer sessions, especially when things start going wrong and you want to see exactly how your friends are coping without you.
Easier Villager Housing And Clearer Feedback
Villager management has also been smoothed out. NPCs no longer require a valid house to spawn, reducing early-game pressure to build awkward housing towers. Villagers without homes will retreat at night, making them unavailable until properly housed.
The Housing Query tool has been upgraded with visual indicators that show exactly what is being checked and where required elements are missing. It is far easier to understand why a room does or does not qualify.
World Seeds Get A Massive Upgrade
World seeds are one of the standout features of Bigger And Boulder. A new World Seed Menu makes special seeds visible and selectable during world creation, instead of being hidden behind obscure codes.
Players can now combine special seeds freely, opening the door to wild custom worlds. New additions include a Skyblock seed that starts you on a tiny floating island with no ground below, and a team-based “royale with cheese” seed that spawns each team in different parts of the map.
Seasonal seeds now allow permanent Christmas or Halloween worlds, while other seeds introduce constant rain, extreme terrain, or dramatically expanded dungeons. Some seeds and combinations remain secret, with unique effects waiting to be discovered by the community.
Dead Cells And Palworld Crossovers Are Live
Two major crossover collaborations arrive with 1.4.5.
The long-awaited Terraria x Dead Cells content is finally playable, featuring Dead Cells-inspired weapons, vanity items, furniture, and more, reimagined in Terraria’s style. Fans of both games will find plenty to hunt down without everything being spelled out upfront.
The Palworld crossover also expands, this time bringing Pals into Terraria itself. Creatures like Digtoise and Cattiva are not just decorative pets, they actively help with tasks such as digging and gathering resources. More Pals are hidden throughout the update for players to discover.
Hundreds Of New Items And Visual Upgrades
Bigger And Boulder adds more than 650 new items, pushing Terraria’s total item count beyond 6,000. New summoner whips, prefixes, transformations like bats and rats, RC cars, and a wide range of new furniture and block sets are included.
The game’s atmosphere has also been upgraded with new biome backgrounds, aurora effects, visible fish while fishing, sun phase visuals, thunderstorms with lightning, and refreshed banner and trophy sprites. Many older sprites have also been quietly updated to better match the modern look of the game.
A Make-A-Wish Vanity Set With Real Meaning
One of the most heartfelt additions is the Heroicis vanity set, created in collaboration with Make-A-Wish New Jersey. The set honours Frank, a longtime Terraria fan who wanted his own vanity set during a critical illness.
The update includes the vanity set itself, a matching film noir shader, and a special obtainment method for players to discover. Frank also shared a personal message with the community at launch, focusing on resilience, gratitude, and looking forward rather than back.
New Languages And Improved Localisation
Terraria 1.4.5 adds full support for Japanese, Korean, and Traditional Chinese. Existing localisations have also been reviewed and improved with help from the community and professional translators. Some additional localisation fixes are planned for the upcoming 1.4.5.1 patch.
Eight New Boss Tracks And A Bigger Soundtrack
Every boss in Terraria now has its own music. The update introduces eight new boss tracks, along with additional songs available through music boxes.
These tracks will be added to the official soundtrack on Steam and other platforms, bringing the total number of new Journey’s End-era tracks to 14.
What Comes Next For Terraria
Re-Logic has been clear that Bigger And Boulder is not the end. While the studio once suggested Terraria’s updates were finished, there is no claim that 1.4.5 is the final chapter. Crossplay support is planned for a future update after this release, meaning at least one more patch is on the way.
For now, Bigger And Boulder stands as a huge moment for a game that is nearly 15 years old and still finding ways to surprise its players. Whether you are jumping back in or starting fresh, there has rarely been a better time to dig in.
