TERRARIA 1.4.5 ‘BIGGER AND BOULDER’ UPDATE
After more than three years of development, Re-Logic has finally set a release date for Terraria's monumental 1.4.5 update. Titled "Bigger and Boulder," this massive free expansion launches tomorrow, 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 you need to know about what's coming to the beloved sandbox adventure game.
OFFICIAL RELEASE DATE CONFIRMED: JANUARY 27, 2026
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."
This marks a significant milestone, as the update will launch simultaneously across all platforms including PC (Steam, GOG), PlayStation, Xbox, Nintendo Switch, and mobile devices. This unified release represents Re-Logic's commitment to platform parity and sets the stage for future cross-play functionality.
EPIC CROSSOVERS: DEAD CELLS AND PALWORLD JOIN TERRARIA
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

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

BOULDER BONANZA: THE UPDATE'S NAMESAKE FEATURE
True to its "Bigger and Boulder" title, the update introduces a comprehensive expansion of Terraria's iconic boulder hazards:

WORLD GENERATION AND SEEDS
SKYBLOCK SEED
The highly anticipated Skyblock seed creates a uniquely challenging experience. Players start on a custom floating island with extremely limited initial resources, forcing creative problem-solving and resource management from the very beginning. This hardcore mode has been extensively playtested by the development team and promises to offer a fresh take on Terraria progression.

New movement options expand how players traverse their worlds:
• Roller Skates - Grind along minecart tracks for stylish traversal

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.
POST-LAUNCH PLANS AND CROSS-PLAY
While 1.4.5 may be marketed as Terraria's final major content update, Re-Logic's history suggests they may continue supporting the game if community interest remains strong. The studio has previously called multiple updates "final," only to return with more content.
CROSS-PLAY DEVELOPMENT
Re-Logic confirmed in October 2023 that cross-play functionality is in development but won't arrive until after 1.4.5's release and any necessary hotfixes. Once the update is stable, cross-play implementation will be the next major technical milestone, potentially arriving later in 2026.
"Please note that we do NOT expect Crossplay to be available until a while after Terraria 1.4.5 releases and all hotfixes, etc. are complete," the team stated in a State of the Game update.
EXPECTED POST-LAUNCH SUPPORT
Based on previous major updates, players can expect:
• Several balance patches in the first few weeks
• Community feedback integration
• Bug fixes for any launch issues
• Potential minor content additions based on player response
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.

FREQUENTLY ASKED QUESTIONS
WILL 1.4.5 WORK WITH EXISTING WORLDS AND CHARACTERS?
Yes, your existing saves, characters, and items will be preserved. The update adds content rather than removing it. However, generating a fresh world is recommended to see all new features, particularly world generation changes and the expanded seed menu.
WILL MY MODS WORK WITH 1.4.5?
Initially, no. Major updates typically break mod compatibility. The tModLoader framework will need updating, which usually takes several days to weeks. Check with individual mod creators for their update timelines.
IS THIS REALLY THE FINAL UPDATE?
Re-Logic has marketed 1.4.5 as a final major update, but they've said this before. While the studio seems committed to moving on to new projects, their history suggests they may continue supporting Terraria if community demand remains strong.
WHEN WILL CROSS-PLAY BE AVAILABLE?
Cross-play is not included in 1.4.5 but is expected "a while after" the update releases and all hotfixes are complete. No specific timeline has been announced, but it could arrive later in 2026.
DO I NEED TO START A NEW CHARACTER OR WORLD?
Not required, but recommended if you want to experience all new world generation features. Most additions will work in existing worlds, but fresh generation provides the cleanest experience.
