After years of anticipation, delays, and multiple “final update” announcements, it is now official: Terraria 1.4.5 has been released. Confirmed by Re-Logic and covered by major outlets such as PC Gamer and IXBT Games, update 1.4.5, also known as “Bigger & Boulder”, marks the final content update for one of the most influential sandbox games of all time.
Released globally on January 27, 2026, Terraria 1.4.5 concludes more than a decade of active development, delivering crossover content, new gameplay systems, interface improvements, and numerous additions requested by the community over the years.
This article provides a complete, source-faithful breakdown of what Terraria 1.4.5 includes, why it matters, and how players can experience the update at its best—especially in multiplayer.
Terraria 1.4.5 Release Date and Global Launch
According to Re-Logic and a Steam announcement referenced by PC Gamer, Terraria 1.4.5 launched on January 27, 2026, following nearly three years of development.
Re-Logic intentionally delayed the update to ensure a global, simultaneous release across all platforms, avoiding staggered launches. The studio also confirmed it chose not to release the update during the Christmas period in order to avoid crunch and allow developers time with family, a decision publicly explained in December.
The result is a fully synchronized launch, marking the definitive version of Terraria.
Why Terraria 1.4.5 Is Considered the “Final” Update
Re-Logic has described update 1.4.5 as the “final” update for Terraria, continuing a tradition of humorously named final patches. However, unlike previous announcements, 1.4.5 represents a true end-of-content milestone.
As reported by IXBT Games and PC Gamer:
- The update closes the main development cycle.
- Content additions are extensive and celebratory in nature.
- The focus is on refinement, collaboration, and long-requested features rather than future expansion hooks.
Terraria 1.4.5 stands as a capstone to a game originally released in May 2011.
Major Crossover Content: Dead Cells and Palworld
One of the most notable features of Terraria 1.4.5 is the inclusion of two official crossover collaborations, confirmed by Re-Logic.
Dead Cells Collaboration
The Dead Cells crossover introduces themed content inspired by the action-platformer, including:
- New weapons
- Items and entities styled after Dead Cells
These additions integrate directly into Terraria’s progression systems rather than existing as standalone novelties.
Palworld Collaboration
The Palworld crossover adds content inspired by Palworld’s creature-based mechanics, including:
- Palworld-themed creatures
- New interactions tied to these entities
PC Gamer specifically highlights a summonable Digtoise capable of mining through blocks, emphasizing utility rather than pure cosmetic appeal.
New Gameplay Features and Additions
Based strictly on official coverage and trailers referenced by IXBT Games and PC Gamer, Terraria 1.4.5 includes a large number of gameplay additions.
Transformation Mounts
Players can now transform into various creatures, including:
- Bats
- Rats
- Velociraptors
These transformations function as mounts and alter player movement and interaction.
New Environmental Objects
The update adds numerous special boulders with unusual behaviors, including:
- Boulders that fall upward
- Boulders that bounce between ores and chests
These objects expand environmental interaction and world unpredictability.
Vertical Conveyors
As shown in the official trailer, vertical conveyor systems have been added, expanding automation and item transportation possibilities.
New Entities and Creatures
Confirmed additions include:
- A pufferfish
- Six new slime variants
- Additional world entities tied to the update’s themes
Interface, Inventory, and Observer Improvements
Beyond content, Terraria 1.4.5 also introduces meaningful quality-of-life updates.
According to IXBT Games:
- The crafting interface has been updated
- Inventory interaction has been improved
- A new observer mode has been added
These changes improve usability, accessibility, and viewing capabilities, particularly for multiplayer sessions and content creators.
Music Blocks and Additional Items
Re-Logic has also added:
- Music blocks
- Dozens of new items not tied to licensed crossovers
These additions contribute to Terraria’s sandbox depth and creative potential without altering core balance.
