Astroneer’s latest update, version 1.78, has deployed across PlayStation, Xbox, and PC platforms, fundamentally altering the late-game experience for the space-faring sandbox title. The patch, released on March 11, 2026, delivers a powerful one-two punch: granting players unprecedented control over Megatech gameplay systems through new Custom Game settings while simultaneously rebalancing the economy of endgame Megastructure construction.
Unprecedented Control with Megatech Custom Games
The centerpiece of update 1.78 is the expansion of the Custom Games system into the realm of Megatech, the game’s complex endgame building system. This new suite of options empowers players to tailor their experience far beyond the standard parameters, effectively allowing them to become architects of their own game balance.
Customizable Recipes and Mechanics
For the first time, players can directly modify the recipes for Megastructures and their component modules. The Custom Game menu now allows adjustments to both the types of ingredients required and their quantities, enabling players to create more accessible or more challenging resource economies for these monumental projects. Print speeds for these massive structures can also be accelerated or slowed, adding another layer of control over the pacing of endgame progression.
Environmental and System Tweaks
The customization extends deeply into the unique mechanics of each Megastructure. On the Orbital Platform, players can now adjust the maximum number of chained Mega Terrain Platforms and even modify the intensity of gravity, allowing for truly unique orbital construction sites. The Biodome becomes a fully configurable ecosystem where plant growth rates, wilting timers, and plant death can be fine-tuned, transforming it from a static greenhouse into a dynamic, player-managed biome.
Quality of Life and Challenge Modifiers
Other notable customizations include the ability to set integrated Hydrazine canisters on the Intermodal Terminal to provide infinite fuel, removing a key logistical constraint for shuttle networks. The Museum’s donation milestone requirements can also be scaled, allowing players to adjust the grind for completionist goals. System Games has included a note cautioning that some extreme modifiers may impact game performance or restrict access to certain missions, advising players to use the tools thoughtfully.
Significant Megastructure Recipe Reworks
Alongside the new customization tools, update 1.78 implements sweeping, permanent reductions to the construction costs of several key Megastructures. These changes are designed to improve balance and reduce potential frustration, ensuring that these monumental projects remain challenging but less reliant on exhaustive resource farming.
Intermodal Terminal Cost Slashed
The Intermodal Terminal, the hub for interplanetary rail and shuttle logistics, has seen the most dramatic reductions. The required Resin has been cut from 150 units to just 50. Aluminum, Ceramic, Steel, and Titanium Alloy requirements have all been reduced by 50% or more. This overhaul makes establishing a core transportation network significantly more achievable in the mid-to-late game.
Biodome and Museum Adjustments
The three-stage Biodome project has also received substantial cost trimming, particularly in its Resin and specialized gas requirements. For example, Stage 1 Ammonium needs dropped from 100 to 40, and Stage 2 Nitrogen requirements were halved from 160 to 80. The Museum, which catalogs a player’s collection of flora, fauna, and artifacts, is now less costly to initiate, with its Stage 1 Compound requirement reduced from 300 to 200 and Copper and Glass needs also lowered.
Comprehensive Bug Fixes and System Polishing
Beyond the headline features, update 1.78 addresses a long list of bugs and issues that have plagued the Megatech expansion and core gameplay, demonstrating a commitment to polish and stability.
Megastructure Placement and Multiplayer Fixes
Numerous issues with the core act of building Megastructures have been resolved. Problems with Construction Anchors spawning incorrectly on landing pads or displaying erroneous holograms have been fixed. A critical multiplayer bug that caused the Megastructure Component Printer to display generic “Ingredient” text instead of specific recipe names has been corrected, greatly improving the cooperative building experience.
Individual Megastructure Refinements
Each major structure received targeted fixes. The Intermodal Terminal no longer crashes when unpacking a shuttle, and resource transfer between canisters and shuttles now functions correctly. The Orbital Platform now properly allows the attachment of Repeaters and Power Sensors to its surface. The Biodome’s Mega Deconstructor has been updated to correctly convert plants back into recoverable seeds, adding a new layer of resource management. The Museum now correctly accepts Storm Data donations and has resolved several issues with its Display Case mechanics and reward claiming.
Legacy and Quality-of-Life Resolutions
The patch also cleans up lingering issues from previous updates. It fixes multiplayer rejoin problems related to Proximity Repeaters, ensures players receive final rewards from the Glitchwalkers mission, and resolves an infinite oxygen exploit. Various UI issues, including incorrect control prompts on Xbox for PC and missing tooltips, have been addressed, creating a smoother interface experience.
This update represents a significant evolution for Astroneer’s endgame, shifting from a fixed set of monumental challenges to a more flexible and player-directed experience. By combining deep customization with thoughtful rebalancing and extensive bug fixes, System Games has not only added new tools but has also refined the foundation upon which players build their galactic legacies. The result is a sandbox that more fully respects the player’s time and creative vision, inviting both veterans and newcomers to reshape the solar system on their own terms.
