Today finally marks the release of the long-awaited Megatech update! There’s a lot of content packed into this one, even beyond all the content pertaining to the new DLC. Speaking of which, that’s a good place to start.

Note: Our Nintendo Switch release for this update will arrive in early 2026. We’ll share an update once we have more to share.

The following is an exhaustive list of the changes and new content being added to the game. Steer clear if you’d prefer to go in blind and discover everything for yourself.

##### **Megatech DLC**

Those who bought the new expansion and completed the pre-requisite missions will be welcomed by a new Mission in their log, where a new virtual assistant by the name of Beepy will walk you through the steps to unlock the exciting new Megastructures technology of Megatech! [Give this guide a look](https://steamcommunity.com/games/361420/announcements/detail/601920231116377230) to ensure you’ve progressed enough to get started.

- New Mission lines have been added to guide Astroneers through unlocking all of the new Megastructures.

##### **New Megastructures**

The following three Megastructures are exclusive to the DLC.

**Orbital Platform**: Space-based observation and science platform developed by the Vastar Infrastructure Research Institute. A Megastructure that can be launched to orbit a planet of choice, offering a vast ring-shaped build space with special conveniences and the MEGA-Mini Asteroid at its center. You only get one, so choose wisely, it's not an easy thing to move around. Features:

- **Gravity**: This remains consistent throughout the top side of the platform, even when you jump onto the Asteroid. Walking off the edge will result in falling into space, but you’ll be safely recovered and placed right back.

- **Power & Oxygen**: The orbital platform contains its own oxygen supply, so no tethers are needed here. As for power, you’ll need to provide that, but there are convenient cable ports through the whole platform to help distribute power.

- **Megaception**: With a few limitations, you can build other Megastructures on top of the Orbital Platform, as long as you build it on the ring itself. Just keep in mind that some Megastructures are limited to either just one or one per planet.

- **Orbital Relocation**: You can spend Astronium as fuel in order to move the Orbital Station into orbit of another planet if you change your mind.

- **MEGA-Mini Asteroid**: An Asteroid of pure soil that can be infinitely reshaped into one of various shapes: Asteroid in two different variants, Sphere, Donut, Flat Platform, Resin and Compound.

- **Upgrade Stages**: Upgrading the Orbital Platform to Stage 2 adds a Megastructure Component Printer. Stage 3 unlocks free flight on the Orbital Platform, even in Adventure Mode.

- **Megastructure Component Printer**: A Stage 2 Orbital Platform will have the ability to print Construction Anchor Landing Pads and its associated Mega Module, the Mega-Terrain Platform.

**Orbital Platform Mega-Modules**:

- **Mega-Terrain Platforms**: Can be placed on the edge of the Orbital Platform or another Mega-Terrain Platform to extend the edge with flat platforms made of terrain.

**Biodome**: A peaceful place to plant and harvest plants. Automate the process and gain planetary buffs. Only one per planet. Features:

- **Seed Harvest**: Biodome harvests are a bit different compared to what you get out in the wild. Instead of Organic, you can harvest Seeds from most regular plantable plants in the Biodom
