Terraria 1.4.5 Bigger & Boulder Update Explained
von Jolynne M.
After more than a decade of updates, Terraria continues to prove why it is one of the most replayable sandbox games ever made. The 1.4.5 update, officially titled Bigger & Boulder, is one of the most ambitious patches the game has seen in years. Rather than focusing on a single system or endgame tweak, this update touches nearly every part of the experience, from crafting and interface improvements to new items, physics chaos, and multiplayer polish. For both new players and longtime veterans, Bigger & Boulder feels less like a routine update and more like a soft expansion!
What Is Bigger & Boulder?
Terraria 1.4.5 is a major content and quality of life update that expands core systems, adds hundreds of new items, and improves how the game feels to play, especially in multiplayer. It feels closer to a mini expansion than a standard patch.
Biggest Changes at a Glance
- Revamped crafting interface that is easier to browse and search
- Crafting can pull materials from nearby chests
- Hundreds of new items including weapons, tools, vanity, and utility gear
- New boulder types with unpredictable physics and interactions
- New pets, mounts, and transformation-style movement options
- Visual and audio improvements across the world
- Multiplayer clarity and quality of life improvements
Crafting and Quality of Life Improvements
One of the most noticeable changes is how much smoother crafting feels. Finding recipes is faster, managing inventory is easier, and long building sessions are far less tedious. These improvements help solo players but make an even bigger difference for groups sharing resources on a server.
New Items and World Chaos
The update adds a massive number of new items that expand how players approach combat, exploration, and building. New boulder variants lean into Terraria’s love of surprise, making exploration more dangerous and entertaining. The world feels more alive and unpredictable, especially underground.
Pets, Mounts, and Crossovers
New pets and mounts add personality and mobility without breaking progression. Some mounts focus on fun movement or transformation rather than power. Crossover content is integrated naturally and feels like a bonus rather than a distraction.
Why This Update Is Great for Multiplayer
Many changes in Bigger & Boulder are especially noticeable in co-op play:
- Shared crafting is easier and faster
- Boss fights are clearer and smoother
- Large worlds feel more stable and organized
- Less time managing items, more time playing together
