Besiege

The Broken Beyond expansion launched on June 22, adding an 11-level space campaign in the Aranea star system, new spacecraft-building tools, and a sandbox spanning planets and moons. September’s Multiverse update then massively expanded playable space, while adding new fuel-management content and the Shattered Citadel campaign level.

• The Broken Beyond: The expansion delivered a substantial new space-focused layer to Besiege.
  • Aranea: Added 11 campaign levels featuring encounters with the Void Drifters and Xenomaws.
  • Space Sandbox: Added explorable planets and moons, plus a multiplayer space environment.
  • Space Blocks: Added the Booster, Control Thruster, Inertial Steering, Parachute, Rocket Fin, Grid Fin, Powered Metal Wheel, fuel storage, and fuel-management blocks.
  • Level Editor: Added 51 objects, along with secondary objectives and new achievements.
  • Mac Support: Added full support for The Broken Beyond on Mac.
• Spacecraft Systems: The Broken Beyond introduced the New Fuel System, which tied together fuel capacity, thrust, and vehicle weight. Multistage systems improved mass efficiency, atmospheric effects changed aerodynamic design, and space-specific fire behavior altered propulsion strategies.
• Multiverse Expansion: Multiverse grew from a 2 km³ maximum map size to 16 km × 8 km × 16 km, with multiplayer bounds expanded to match. The update also added Fuel Pump, Shattered Citadel, the Fuel Gauge Advanced Mode, and the Black Hole to sandbox play.
• Gameplay Tools and Tuning: God Tools added Infinite Fuel, Disable Firespread, and Click to Explode options, while Flamethrower changes made armor block its flames and connected it to the new fuel system. Cannon and Water Cannon maximum power increased from 2x to 3x.
• The Splintered Sea and Modding: New The Splintered Sea water tutorials taught aquatic-machine construction, while minChangeset, maxChangeset, and useMipMaps gave assembly and resource creators more version and texture control.

The Withered King and Admiral Drasckar joined Besiege’s campaign rulers in a March 2025 content update, with Drasckar receiving a visual makeover. The update also deepened machine construction with new artillery options, grenade behavior, and editor tools, while Machine Autosave and Additive Loading later improved workshop workflows.

• Campaign additions: The Withered King and Admiral Drasckar completed the campaign’s ruler lineup, while two Source Cube skins became unlockable through the base-game and Splintered Sea Completionist achievements.
• Weapons and machine building: Cannons gained a projectile-size slider and selectable chainshot ammunition, while Grenades received a fuse delay that began when fire was applied. Joint Stress Mode also visualized block collisions and breaks, and Advanced Building Mode enabled value fields by default.
• Machine workflow: Machine Autosave added customizable save limits and storage duration, while Additive Loading allowed multiple saved or workshop machines to be loaded without deleting the existing build. Paint Bucket search and sorting, Camera Snapping, Orthographic View, and directional readings for the Speedometer expanded the construction toolkit.
• Simulation and editor updates: Zone 36: The Frozen Path received adjusted wind strength, and humanoid AIs gained drowning poses. Piston, Rope & Winch, Grenade, and Flying Block received new sounds, while High Quality SSAO became sharper.
• Technical changes: Key Emulation was optimized for ticks with many key or variable uses, and blocks using Dials and Levers received rendering optimizations. Leaderboards were disabled indefinitely on M-core Macs after integration-related crashes.

The Splintered Sea expansion launched on May 24, 2024, bringing Besiege its first water-focused campaign, an ocean sandbox, eight aquatic blocks, and hydrodynamic machine building. Its July extension added five more campaign levels, while Nintendo Switch and PlayStation 4/5 releases broadened access later in the year.

• The Splintered Sea: The expansion added a substantial new building and exploration space.
  • The Seas of Autilis: A 10-level campaign followed the Offlanders and their shipbuilding expertise.
  • Ocean Sandbox: The new environment included a calm racing zone, a Galleon battle, underwater ruins, marine life, and ancient-beast remains.
  • Aquatic Blocks: Sail Panel, Aquatic Screw, Paddle, Rudder, Harpoon Launcher, Small Barrel, Large Barrel, and Ballast blocks enabled purpose-built watercraft.
• Campaign expansion: The Splintered Sea grew to 15 levels in July, adding optional challenges, the tentacled Tentacle Beast, and a giant shark encounter. Existing campaign levels also received revisions, while Tolbrynd’s final level was later redesigned.
• Water simulation: Water Simulation introduced waves, wakes, splashes, buoyancy values, shape-dependent drag, and underwater explosive effects. The Center of Buoyancy visualization, customizable Barrel blocks, and heavier Ballasts gave builders more control over stability and balance; water also became available in Multiplayer and the Level Editor for expansion owners.
• January 2025 update: Legacy Sandbox returned with refreshed models, textures, and a larger environment, alongside 25 new achievements, Global Leaderboards tracking time, damage, and block score, and campaign rulers who joined the final levels of their islands.
• Console releases: Nintendo Switch launched in September with touch-screen building controls, and Besiege reached Nintendo Switch and PlayStation 4/5 in Asia in December. The console versions did not include Multiplayer or the Level Editor.

The Edge Detector Logic Gate arrived in Besiege’s January 2024 update, giving machine builders a new way to react to edge conditions. The update also changed wheel collider and acceleration mechanics and delivered major Surface Block and Vacuum Block performance improvements, alongside new modding hooks and construction controls.

• New construction logic: The Edge Detector Logic Gate was added, while the Decoupler worked correctly with Automation instead of failing to trigger.
• Wheel and weapon mechanics: Wheel Collider and Acceleration Mechanics were updated with a slightly rounder collider and new acceleration behavior affecting deceleration. New Wheels grounded properly again, and Steam Cannons were fixed.
• Simulation and building tools:
  • Surface Block simulation start times decreased significantly.
  • Vacuum Block used a more reliable, performant cone of effect, and no longer affected blocks in reverse.
  • Camera Targeting and Movement gained updated targeting and zoom-dependent WASD movement.
  • Grabber Button controls allowed manual attachment and detachment when auto-grabbing was disabled.
  • Surface Block gained world-size texture tiling and rotation options.
  • Steering Hinges and Steering Blocks received adjustable tension sliders.
  • Ropes no longer suffered chopping trigger lag, while Drills stopped creating sparks when only the affected block spun and Logs had more consistent collisions.
• Mod support: Mod Meshes became readable by default, and the Generate Colliders callback for Surface Block gave creators more control when generating custom colliders.

Besiege’s 64-bit upgrade was the biggest change, delivering a performance boost for players with powerful computers. The same update added new level-editor objects, a clearer tutorial system, expanded modding tools, and broader language support.

• 64-bit upgrade: Besiege switched to 64-bit, while memory leaks involving skins and block mods were resolved.
• Level-editor additions: New objects included:
  • Floating Crystal
  • Sandbox Mountain
  • Monk Idol statue Italian, Polish, Turkish, Traditional Chinese (Taiwan), and Traditional Chinese (Hong Kong) were also added.
• Tutorial and modding systems: The new tutorial system guided new players through Besiege’s opening steps more clearly. Modders gained a hidden toggle that disabled collision for surface blocks, while surface-block update errors were fixed.
• Progression and building changes: Besiege’s multiplayer achievement requirement dropped from 25 servers to 10, cloud-save capacity increased from 1,000 to 10,000 saves, and Steering Hinges no longer deflected when simulation started.

Krolmar Island served as Besiege’s final single-player campaign island, adding new enemies, fortresses, and secret magics. Logic/Automation Blocks and the Build Surface Feature expanded the game’s machine-building possibilities with sensors, automation, and custom-shaped construction pieces.

• Krolmar Island: Added the campaign’s final island, including new enemies, fortresses, and secret magics.
• Logic/Automation Blocks: Introduced a new block category for automated mechanisms and sensor-driven machines, alongside the Speedometer Logic Block Concept and Angle Detector Logic Block Concept.
• Build Surface Feature: Added customizable blocks and panels for creating custom shapes; the new panels also gained aerodynamic properties for flying machines.
• Symmetry Tool: Added two selection and modification modes plus mirrored deletion of blocks, making large machine builds easier to edit.
• Multiverse and surface systems: Addressed persistent burning surfaces, invalid surfaces and edges, surface duplication undo errors, pin-block flickering, rotated-machine joint errors, and projectiles that failed to despawn.
