Astroneer: Megatech is an indie adventure sandbox expansion that builds directly on the base game's exploration and construction systems. Released in November 2025, it introduces end-game content centered on massive structures and automated resource management for players who have already progressed through core planetary survival and crafting loops.
Gameplay
The core loop centers on planetary exploration, resource gathering, and base construction, now scaled up through new Megastructure projects. Players start by completing the Large Scale Learning mission chain, which requires construction of the Distribution Launcher System to unlock access to Construction Anchors. From there, advanced automation becomes the focus, with systems that handle resource distribution, plant cultivation, and interplanetary logistics at a larger scale than standard bases.
Key additions include the ability to modify terrain on a grand level and balance new mechanics such as plant wilting in dedicated facilities. Existing saves remain fully compatible, allowing seamless continuation of prior progress without resetting any established bases or inventories. The expansion emphasizes careful planning of power, oxygen, and material flows to sustain these larger projects over time.
Game Modes
Astroneer: Megatech operates within the established sandbox framework of the base title, supporting both solo play and online cooperative sessions. There are no separate competitive or story-driven modes; instead, the experience revolves around open-ended world building and automation challenges that scale with player advancement. Cooperative sessions allow multiple players to contribute to the same Megastructure projects simultaneously, sharing the workload of excavation, assembly, and maintenance tasks across shared planetary or orbital sites.
Megastructures
Three primary Megastructures form the centerpiece of the DLC content. The Orbital Platform serves as a vast space-based canvas for station construction, complete with expandable terrain sections and a central asteroid that players can reshape freely using regeneratable soil. The Biodome focuses on large-scale agriculture, introducing seed collection at expanded volumes, mega plant variants, and a wilting system that demands ongoing automation to maintain output. The Museum provides a dedicated space for organizing collected items into up to seven displays, which in turn grant functional perks while also tracking community-visible contributions of bytes, resources, and power for milestone progression.
A free content update released alongside the DLC adds the Intermodal Terminal, enabling automated resource transfers between planets through linked landing pads and shuttle systems. This facility integrates with existing train networks to streamline logistics across multiple worlds.
Is It Worth Playing?
Astroneer: Megatech targets players already invested in the base game's automation and construction systems who seek larger-scale projects and end-game challenges. The expansion delivers concrete new tools for base expansion and resource management without requiring a fresh start. Those who enjoy methodical planning of automated facilities and interplanetary supply chains will find meaningful extensions to the core sandbox loop. Availability on PC supports both single-player experimentation and cooperative building sessions, making it a direct addition for fans of the established gameplay style.
