Changelog for Armstrong Update (added 16 May 2019):

New Features:
* New Mod Manager UI, enabling mods to be accessible on Xbox One and GOG/PDX PC versions

General Fixes:
* 5 Landscaping tools/buildings - Flatten terrain, create Ramp, Change Surface texture and construct Small Rock Formation or medium Rock Formation. They're available since start and do not require research. The Flatten and Ramp tools consume a lot of drone time and require or produce excess of Waste Rock. The Rock Formations are constructed with Waste Rock. The Change Surface tool consumes drone time and damages the local soil quality.
* 3 Special Projects - Capture Meteors, launch High-Speed Comm Satellite and Launch SETI Satellite. They become available when the first batch of Planetary Anomalies gets discovered (Sol 10-15) and do not require previous research. These three act as alternative sources of raw materials (Capture Meteors), sponsor research (HGS Satellite) and funding (SETI Satellite).
* 2 new buildings - Large Dumping Site and Rocket construction site. The significantly larger dumping site is because we're now producing and consuming far more Waste Rock. The construction of Rockets was added as an alternative to the buying of Rockets, which is not possible when you lack Funding. The Large Dumping Site is not locked via research, the Rocket requires Advanced Rocketry to be researched. (Advanced Rocketry is a vanilla tech that now enables the construction of Rockets, as well.)
* Self-sufficient dome - you can now place a Basic Dome with minimal life-support buildings. You only need to connect it to a power source. Once constructed, the structures will act as independent buildings. International Mars Mission has a free prefab of the self-sufficient dome.
* New event chains - 19 for the base game, 1 for modding purposes, 9 for Space Race DLC
* New research UI with vertical flow replaced the old research UI

Other fixes and improvements:
* Added order-queuing for Rovers
* Added multi-selection of units for mouse and keyboard and hybrid control schemes. You can use lasso or double-click over a unit type to mass-select nearby units of the same type
* More informative reasons for unavailable diplomacy options
* Fix for proper show/hide behaviour of hex ranges of domes for outside workplaces
* Build Menu: Rovers are moved to separate sub-categories
* Added conditions where colonists can change dome regardless of home availability in other domes
* Double click or Controller Button (X) on items in the build menu, which require known but non-researched techs now open the Research UI
* Trade rockets to rivals are not automated by default
* New Photo Mode effect added - Motion Blur

[PC VERSIONS ONLY] Modding-related fixes and improvements:
* Documented the Lua loading procedure, mod versions and dependencies, creating mods for DLCs and other minor documentation updates
* Added a filter for mods compatible with the game version
* Build menu subcategories are now pre-sets, which can be easily added with mods
* Added a set of mod items that add easily modifiable options to your mods
* Fixed 'copy from' field in building template mod items and mission logo mod items
* Unused tech field icon property removed
* Mod dependencies show if the mod they depend on is missing or incompatible (outdated)
* Added a sample story chain
* Improved mod upload - it provides status update, better UI flow, and feedback about report upload problems
* [PDX modding] Fix to enable auto-update of mods from PDX modding backend
* [PDX modding] Fix for re-uploading mods to PDX modding backend to keep their dependencies entered in the web interface

Uhm, where is this update?
Maxvorstadt: Uhm, where is this update?
Unfortunately there is no small patch installer for this one. You have to download the full offline installer again and install it over the existing game.
That's always the same with gog.
Sometimes the patches show up later, but it takes time. Really, they should do something about it.
Post edited May 19, 2021 by Mondkalb
Please developers, bring a patch for the latest version (1001586), I don`t want to download the whole game and all the DLCs again!
They added a Linux .sh file with the latest Windows build :D

Below and Beyond​


- A new area to explore right beneath your colony. Uncovering what the Martian Underground has been hiding from us, perhaps we can even find something rivaling our wonders.
- Expand your colony into the Underground, providing shelter against the hazards from the surface and bringing you closer to richer deposits.
- Be careful, as there may be underground marsquakes that can lead to dangerous cave-ins.

- Set up temporary mining outposts to extract as many rewards as you can from each asteroid.
- Bring back Exotic Minerals, a new resource exclusive to asteroids, to improve your colony on the Martian surface and its underground.
- Some asteroids may not be as they appear and have a mystery to solve while you are on them.

Recon & Expansion tech

- Unlock multiple specialized buildings, rockets, and upgrades in the underground and on asteroids.
- Gain benefits and upgrades for your entire colony.

Free Update​

Known issues


- Drones that are “busy” with transporting resources do not get added to the cargo of a Lander rocket when the asteroid moves out of range. This can occasionally cause a crash

- Pin menu does not show incoming Asteroid Landers from Asteroids
- There is no warning about an unloaded cargo when launching a rocket back to Earth
- Drones occasionally try to get to the unreachable area on Asteroids in order to gather resources

- Even after clearing debris, the area is uneven and unbuildable
- Some cave-ins are unreachable and therefore cannot be cleared which prevents further exploration.
- Shuttles can fly ‘too high’ vertically in the Underground.

Platform specific:
