Terraria 1.4.5 Update: Bigger and Boulder Release Date

Terraria 1.4.5 Update at a Glance

The Terraria 1.4.5 update launched on January 27, 2026, bringing one of the biggest free content expansions in the game's history. After more than three years of development, Re-Logic finally released Terraria's monumental 1.4.5 update. Titled "Bigger and Boulder," the massive free expansion arrived on January 27, 2026, bringing with it game-changing features, exciting crossovers with Dead Cells and Palworld, revolutionary quality-of-life improvements, and nearly 900 bug fixes.

What began as a small collection of leftover features has grown into one of the most substantial updates in Terraria's 15-year history, rivaling even the celebrated Labor of Love update from 2022. Here's everything that's new in the beloved sandbox adventure game.

Terraria 1.4.5 Update Release Date Confirmed

On January 14, 2026, Re-Logic's head of business strategy Ted "Loki" Murphy officially announced on the Terraria forums that update 1.4.5 would launch on January 27, 2026. The studio had initially targeted a late 2025 release but needed to resubmit certain elements for platform approval, pushing the launch into early 2026.

"We did have to resubmit a few things, which pushed us back a bit further than expected," Murphy explained. "However, we are happy to share that Terraria 1.4.5 will release on January 27th! We have a few more things to get done between now and then, but start the countdown."

It was a significant milestone, as the update launched simultaneously across all platforms including PC (Steam, GOG), PlayStation, Xbox, Nintendo Switch, and mobile devices. That unified release reflected Re-Logic's commitment to platform parity and set the stage for crossplay.

Terraria 1.4.5 Update Crossovers: Dead Cells and Palworld

Dead Cells Collaboration

The highly anticipated collaboration with Motion Twin's acclaimed roguelike Dead Cells brings an exciting array of themed content to Terraria. Players can expect:

• The Beheaded Outfit - A complete vanity set based on Dead Cells' iconic protagonist
• Hanging Flasks - Decorative items that can display various collectibles
• New Weapons - Items spanning all damage types, staying true to both games' design philosophies
• Ram Rune - A mobility item inspired by Dead Cells' movement mechanics
• Wings of the Crow - A unique flight accessory
• Health Fountain - A functional healing station for your base

This crossover was first teased years ago when Terraria content appeared in Dead Cells, and fans have eagerly awaited the reciprocal collaboration ever since.

Palworld Integration

In a surprise announcement, Re-Logic revealed a collaboration with Pocketpair's monster-collecting survival game Palworld, which took the gaming world by storm in 2024. The Palworld crossover introduces:

• Digtoise - A mining companion that can excavate blocks for you automatically
• Cattiva Minion - A summonable ally to fight alongside you
• Foxparks Sentry - A unique sentry that can be carried and used as a flamethrower

These crossovers demonstrate Terraria's ongoing commitment to celebrating the broader indie and survival-crafting gaming community.

Terraria 1.4.5 Update Quality-of-Life Improvements

Game-Changing Crafting System Overhaul

Perhaps the most impactful change for daily gameplay is the completely revamped crafting menu. Players can now craft items using materials stored in any nearby chests, eliminating the tedious task of manually sorting through dozens of storage containers to find specific resources. This modern convenience brings Terraria up to speed with contemporary sandbox games while maintaining its classic charm.

Reforge Safety Feature

Addressing a decade of player frustration, Re-Logic has implemented a safety mechanism when reforging equipment at the Goblin Tinkerer. The system will automatically halt when you achieve the best possible modifier for your weapon or accessory type, preventing players from accidentally clicking past coveted modifiers like "Legendary" or "Unreal."

Enhanced Multiplayer Experience

Multiplayer sessions receive significant improvements, including:

• Spectator mode allowing players to watch others after death
• Improved synchronization across platforms
• Better NPC behavior and interaction systems
• Enhanced touch controls for mobile players

World Generation and Seeds

Skyblock Seed

The highly anticipated Skyblock seed creates a uniquely challenging experience.

New movement options expand how players traverse their worlds:

• Roller Skates - Grind along minecart tracks for stylish traversal
• RC Car - A remote-controlled vehicle that can drive on blocks and background walls

900+ Bug Fixes and Polish

Beyond new content, Re-Logic has addressed nearly 900 bugs accumulated over years of gameplay feedback. The studio emphasizes "countless little things that go into each update," demonstrating their commitment to polish and refinement.

The extended development cycle allowed console and mobile developer DR Studios to implement platform-specific improvements, ensuring the best possible experience across all devices.

What Happened After Terraria 1.4.5?

Re-Logic followed Bigger and Boulder with a series of hotfixes. Terraria 1.4.5.6 arrived on PC in March 2026, focused on bug and exploit fixes. Then Terraria 1.4.5.7 released on PC on 19 August 2026, with the console and mobile versions following once they clear platform certification. Re-Logic calls 1.4.5.7 the latest and last hotfix for Bigger and Boulder, barring any critical fixes.

According to Re-Logic, 1.4.5.7 is mainly a balance update: it changes the stats and functions of existing items, adds some new items and fixes bugs. It also tackles common combat frustrations, such as enemy aggro, invisible hitboxes and Gastropods shooting from off-screen, and reviews whole weapon classes, including throwing weapons.

Is Terraria Crossplay Out Yet?

Not yet, but it's close. Crossplay is arriving in phases, and Crossplay Phase One will be update 1.4.6, the next major update after 1.4.5.7. In its September 2026 State of the Game, Re-Logic said the finishing touches were being put on Phase One and that it should be in players' hands in the near future, with Phase Two to follow as soon as possible.

No exact release date has been announced yet. We'll update this article as soon as Crossplay Phase One has a date.

Community Involvement and Special Additions

The update showcases Re-Logic's deep connection with the Terraria community:

Frank's Vanity Set

In partnership with the Make-A-Wish Foundation, Re-Logic worked with 17-year-old Terraria fan Frank from Rockaway, New Jersey, who is battling a critical illness. Frank's wish was to have his own vanity set in Terraria, resulting in the film noir-themed outfit and accompanying shader effect.

Developer Set

A new developer set honors David "Chicken Bones" Kossen, recognizing his contributions to the Terraria community and modding scene.

Community-Made Paintings

Several new paintings created by community artists will be added to the game's decorative item pool, celebrating player creativity.

Tmodloader Support

The modding community remains central to Terraria's longevity. While major updates typically break mod compatibility temporarily, the tModLoader framework will be updated to support 1.4.5 features. Popular mods should receive updates within several days to weeks after the official release.

Re-Logic continues to provide new hooks, items, and systems that modders can expand upon, ensuring Terraria remains relevant through community-created content long after official development slows.
