Empyrion - Galactic Survival - EmpyrionGame
Hi Galactic Survivalists!
Many of you have already tipped your toes into the Experimental version of Empyrion Alpha 4.0 - so please, ladies and gentlemen, switch to the public version right now!
For everyone else, and because we added a ton of new stuff and a few game-changers, please read on below to get all the info!
We are looking forward to your feedback and, as always: thanks everyone in advance for helping to squash the remaining bugs! :D
Cheers,
Empyrion Dev Team
P.S. We recommend starting a new game in Alpha 4.0. Please note, however, that your old save games are technically compatible in Alpha 4.0 but the visuals (e.g. light intensity - especially during night) will be messed up due to the switch to linear space (see below).
Changelog: Alpha 4.0.0 (Build 658)
New Main Features:
1. Auto Mining Device:
- Added terrain-placeable auto-mining device with 3 Tiers
- Possibility to upgrade from T1 through T3
- Mining rate depends on the Tier and the Source Quality (dependent on the size of the deposit)
2. New HV Handling:
- With the new HV handling your HV will now adapt to the ground, i.e., it will no longer remain horizontal if you drive up a hill
- The new hover engines apply a local force below them (somehow like a virtual wheel). Thus, the position of hover engines and distribution of weight plays a big role now
- Added visual overlay for "Center of Mass" and "Center of Vessel" (Use building-helper menu to show; default button: N)
- Added artificial mass block that adds additional weight and can be used to balance the Center of Mass of the vessel for improved flight and hover behavior
- Added T1 and T2 hover engines with new 3d models
- Added Hover Booster device that allows HV to perform jumps (old Hover Engine Model)
- Changed HV starter block: no hover engine placed on starter block anymore
Note: HVs from blueprints and from the workshop need the new hover engines to be added. The old “Hover Engine model” now only adds the Hover Booster feature to your HV but it will not make it hover
3. Repair Block:
- Added "Repair Bay" block for CV and BA
Note: to activate auto repair just place a de-activated SV / HV / CV on top of repair block; Limit: max 1 Repair Block per CV/BA for now; CV Repair Bay can only repair SV and HV. BA Repair Bay can repair all vessels.
4. LCD Screens:
- Added re-writable LCD Screens
- Screen content saves with blueprint
5. Ship Registry:
- Structure overview window with “Waypoints” and “Show on Map” feature
- The registry list shows all your vessels and bases anywhere in the solar system
- If you are in the same playfield, possibility to access certain features of your vessels and bases via Control Panel remote access (e.g. turret settings, power up or down, etc)
- You can set a waypoint as a guide or show the position of the selected target on the map
- Structures that are chosen as waypoint, are now displayed in yellow on the map and have a yellow arrow and tag on the HUD (remove a waypoint by clicking on the waypoint button again; you can have more than one waypoint active at the same time)
6. Faction-based Discovery System:
- Added player-centered discovery for multiplayer (i.e., when a player discovers a POI / deposit this discovery is no longer visible for everybody on server; players in a faction share their discoveries)
7. Separation of Small and Large Blocks:
- Separated small and large blocks (hull, windows, truss blocks etc): please note that we had to re-balance the weight of many blocks; Small Blocks = SV,HV; Large Blocks = CV,BA
- The separation will allow us to make a much better balancing of hitpoints and weight
- CV and Bases got more hitpoints for their basic building blocks and windows (for example: Steel 500 HP, Hardened Steel 1000 HP, Combat Armor 2000 HP). As a result, they are now heavier and need more materials when crafted.
- All hull, window and truss blocks are automatically updated to the corresponding new block when spawning a pre-Alpha 4.0 BP. Please note: Pre-1.0 Alpha Blocks are not auto-updated. Blueprints that still have these blocks will be shown as RED in your blueprint library. You still need to swap them manually.
8. New Weapon Balancing (Step 1):
- Rebalanced all mounted weapons and turrets - let us know what you think
- Separated CV and BA turrets as preparation for upcoming CV-BA rebalancing (their stats are identical at the moment; subject to change!)
- Added homing missile to Turret Rocket (BA / CV): the homing missile will follow the attacked vessel during a certain time. These turrets will now be much more effective against fast moving targets.
- Added new Pulse Laser Turret (BA and CV)
- Added Flak Turret for CV
- Added Minigun Turret and Artillery Turret for BA
- Adapted ammo templates to new balancing
- Balancing Stage I: Added limit to number of mounted and turret weapons (performance and balancing reasons). "Max Count" indicates now how many weapons can be placed on a structure for Survival Games.
Please note: Blueprints that violate these limits will be shown as ORANGE in your Blueprint Library and can not be used in Survival mode. You can still spawn and change them in CREATIVE mode - or use them in multiplayer if the server admin decides to disable the Max Count.
- Added 'EnableMaxBlockCount' in dedicated.yaml (thus you can disable MaxCount on your dedicated server if you prefer)
9. Code Locks:
- Added code locks to several blocks (e.g. Doors, Hangar Doors, Cargo Boxes, Fridges, Constructors etc.)
10. ATM Machine:
- Added ATM block: With ATM machine you can transfer money from / to account (you now must use ATM to transfer money to your account; Open ATM GUI and add money by dropping gold coins and credit cards to the intake ; Remove money by creating a moneycard; It is not possible anymore to “consume” stacks of Gold Coins or Credit Cards for adding the value to your bank account!)
- Replaced credit card with a money card that can hold a flexible amount of money
11. Switch to Linear Space:
- Switched from gamma to linear space: this change had a major effect on the overall lightning in the game and how the physically-based rendering (PBR) works. If you want to read more about gamma vs linear color space, check this out:
https://docs.unity3d.com/Manual/LinearLighting.html
It is hard to capture the effects of linear space in screenshots - just start the game and convince yourself of the new lightning and the different look & feel of linear space (btw: in the last screenshot you see the new Multitool T2)
12. Dynamic Character (UMA):
- Added fully dynamic character (so called UMA): for now you do not see any difference to the old model but with this new approach we will be able to easily change armor, jetpack, etc on the character. In addition, we will be able to integrate character customization (face, hair, beard, size, etc).
13. Separation of Client and Server:
- Client and server are now separated
- You can download “Empyrion - Galactic Survival Dedicated Server” from the Steam client via Library -> Tools
- If the Empyrion dedicated server does not show up under Tools in your Library, you can install it via SteamCMD as follows:
a. Install SteamCMD from https://developer.valvesoftware.com/wiki/SteamCMD
b. Open console/command line prompt and navigate to the directory you installed SteamCMD (make sure SteamCMD is not running, otherwise exit it with "quit")
c. Enter the following command:
steamcmd +login anonymous +force_install_dir "../Empyrion - Dedicated Server" +app_update 530870 +quit
Following this procedure will install the Empyrion Dedicated Server in the folder “Empyrion – Dedicated Server” beside the folder where steamcmd is installed. If needed, you may change the folder name to your liking.
Other Changes / Improvements:
Blocks/Items/Building:
- Added color-able / texture-able wings for SV
- Added new doors that open vertically

- Added new block groups: Landinggear Blocks SV and Landinggear Blocks Heavy SV (Added short versions of landinggear single and double)
- Added new block group: Landinggear Blocks CV (added more landinggear models for CV)
