Industry and transport
Create provides machinery, automation and railways. TFMG adds oil refining, fuels and metallurgy. Aeronautics lets players design flying machines. Together, these systems form a shared industrial gameplay experience.
World and progression
As their production and equipment develop, players unlock further opportunities and explore new areas of the world. The six-ring map illustrates progression through resources, climate and examples of structures. It does not show exact ore-deposit or building coordinates.
Six-ring world map →PvE, PvP and territory protection
The pack includes Scorched Guns, Born in Chaos and Create Big Cannons. Warfare and heavy-weapon gameplay are actively being refined. Claims use Open Parties and Claims with project-specific additions; protection and interactions during conflicts are governed by the server rules.
Rules and help on Discord →Economy and environment
Create Numismatics and the project’s own solutions support economic interaction. Cold Sweat and Ecliptic Seasons add temperature and seasons to survival. The catalogue introduces the main mods in the pack.
Main mod overview →Custom mods and optimization
SteamSteelCore, Ore Rings, Dungeon Rings, Black Frost and other project additions extend interfaces and world features. Community optimization solutions are complemented by in-house development. Fixes and improvements continue as the project evolves.
Players and project development
Players have a substantial say in the project’s direction, and the administration talks with the community directly. Within the game, freedom of actions, thought and speech is supported without censorship; everyone is responsible for their own words and actions. General rules and current discussions are available on Discord.
Plan your industry around the world
The six-ring map connects resources, climate and structures to different world zones. Use it to choose the next resource you want to reach and the production or transport that would make the journey useful. A factory, railway or aircraft is a project you can develop toward that goal; players choose their own route.
Before moving a base or starting a supply line, compare the zone’s resources and climate with your equipment and supplies. The map is a progression schematic, not a live map of player builds or exact ore coordinates.

What is specific to Steam & Steel?
Project modules such as SteamSteelCore, Ore Rings / Dungeon Rings and Black Frost complement the Create, Aeronautics and TFMG core. The catalogue explains their role alongside the main gameplay mods. These are project-specific additions, rather than a claim that every upstream mod was written by us.
Modpack and joining
Which enchantment add-ons are included?
Create: Enchantment Industry 2.4.2 is confirmed. Enchantable Machinery is not listed in the checked setup. If a particular add-on is essential to your playthrough, ask about the current pack on Discord.
Can I use my preferred launcher?
Steam & Steel Launcher is available for Windows. For another compatible launcher, download the MRPACK or ZIP, follow its README for Minecraft 1.21.1 and NeoForge 21.1.235, and add the required Java argument. AutoModpack downloads and updates files when connecting; the IP alone is not enough to join.
System requirements
| Computer RAM | 16 GB |
|---|---|
| Memory allocated to the game | Start with 6 GB; up to 8 GB if enough RAM remains available |
| Free storage | 20 GB on an SSD for the game and updates |
| Processor | Modern 64-bit CPU; a tested minimum model has not been established |
| Graphics | Minecraft Java 1.21.1-compatible graphics, current drivers; start without shaders |
| Java | Java 21, 64-bit |
This is a provisional recommended profile, not a measured minimum. A tested minimum, VRAM requirements and FPS measurements for the full public pack have not been established yet. Game memory is part of the computer’s total RAM: leave headroom for the operating system, Java’s native memory and other applications. Shaders, long render distances and large factories need more headroom.
Install the Steam & Steel modpack
The official Windows launcher is the recommended route. Another compatible launcher can use the supported MRPACK or manual ZIP from our downloads page. The small bootstrap is an installer profile: AutoModpack downloads the gameplay files separately when you connect.
- Create a separate game profile. The current native bootstrap specifies Minecraft Java 1.21.1, NeoForge 21.1.235 and Java 21 x64. Keep the installation in its own game folder.
- Choose the correct download. Import the website’s MRPACK using your launcher’s modpack import function. On Windows, the manual ZIP contains
Install-Mods.cmd; follow its README to download the official AutoModpack file. - Set up compatibility before first launch. For third-party launchers, open the profile folder and run
Show-Java-Argument.cmdon Windows. Copy its complete output, including quotation marks, into Java/JVM arguments. The includedsteamsteel-client-compat-startup.jarbelongs in the game folder, not the mods folder. The official launcher handles the project setup itself. - Allow enough memory. Start with 6 GB for Minecraft on a computer with 16 GB RAM. Increase to 8 GB only if enough remains for the operating system. The requirements table explains this provisional starting profile.
- Connect and follow AutoModpack. Add
steamsteel.minecraft.best, accept the pack download/update and follow any restart prompt. Reconnect after the required restart. Personal download access is issued during the normal connection; the public certificate fingerprint is a trust check, not a shared download password.
Java argument for Linux, macOS or a moved profile
Use the absolute path to the startup agent in this game profile and retain its flags:
"-javaagent:/FULL/PATH/steamsteel-client-compat-startup.jar=copycats,audio,tfmg"
Replace /FULL/PATH/ with your actual profile path. Keep the whole argument quoted when the path contains spaces. On Windows, run Show-Java-Argument.cmd again after moving the profile.
CurseForge starter 2026.11.09-bootstrap.1 is a separate Beta artifact and lacks this compatibility component. Until a corrected starter is verified, use the supported website launcher/MRPACK/ZIP instructions above.
Installation and connection help
Wrong version or missing mods after importing
Check the selected game profile, Java 21 x64 and NeoForge version. For a third-party launcher, check that the required Java argument points to the agent in this profile. Complete AutoModpack’s update and restart prompts before reconnecting.
A mod or NeoForge download fails
Keep the exact error, failed download URL and the installation step. Share those details in Discord so the team can distinguish a launcher problem, unavailable upstream file and network-access problem. Remove account tokens and personal details from logs before posting.
The game runs out of memory or performs poorly
Use the starting memory recommendation, launch without shaders and reduce render distance first. Leave memory for Windows and other applications. Report your RAM, CPU, GPU, allocated game memory and the situation where the slowdown appears; the project does not claim a tested minimum or guaranteed FPS.
