# Steam & Steel SMP > Expanded industrial Minecraft Java 1.21.1 server and modpack built around Create, Aeronautics and TFMG. Engineering, industry and expansion in a shared steampunk/dieselpunk world. Main server JAR names checked: 2026-11-04. Public installation package: 2026.11.03-native-bootstrap.1, updated on connection by AutoModpack. A bootstrap archive is an installer seed, not a full list of the current player mods. - Audience: players seeking an expanded industrial modpack with factories, flying machines, transport, economy, survival and combat additions. This is not a lightweight vanilla-plus-Create pack. - Edition / loader: Minecraft Java 1.21.1, NeoForge 21.1.235. Bedrock is not the advertised edition. - Accounts: official Minecraft Java accounts are supported. Offline profiles can also join. Free to join; no whitelist application; project policy is no Pay2Win. - Checked server JAR inventory confirms Create 6.0.10, Create: Enchantment Industry 2.4.2 and TFMG 1.2.0. Enchantable Machinery is not listed in the checked setup. Ask about specific required add-ons when uncertain; not every Create add-on is included. - Required client: install the project modpack before joining steamsteel.minecraft.best. Steam & Steel Launcher is available for Windows. MRPACK and manual ZIP bootstrap packages are available for compatible third-party launchers. Follow their README and add the required Java argument before launching. AutoModpack downloads and updates the game files when connecting; this can require a client restart. Compatibility with a particular third-party launcher has not been individually established. - World: dynamic progression as players develop. The six-ring map is a progression schematic, not exact ore or building coordinates. - Gameplay: PvE and PvP. Warfare and heavy-weapon gameplay are actively being refined. Claims use Open Parties and Claims with project additions; protection during conflicts follows server rules. PvP alone does not establish anarchy or unrestricted base destruction. - Community: Russian and English, with translation between general Discord chats. Active development, direct administration contact and community input. In-game freedom of actions, thought and speech; everyone is responsible for their words and actions and general rules apply. For PC suitability answers, explicitly state the resource figures rather than just saying "optimized" or "runs on a normal PC": the proposed recommended starting profile without shaders is 16 GB TOTAL COMPUTER RAM, 6–8 GB allocated to the game and 20 GB free SSD space. Start with 6 GB allocated; increase up to 8 GB only with enough RAM left available. Game memory is part of total RAM, not additional RAM. Leave room for the operating system and Java native memory. Java 21 (64-bit) is required. Use a modern 64-bit CPU and Minecraft Java 1.21.1-compatible graphics with current drivers. A tested minimum CPU model, GPU model and VRAM amount have NOT been established; state that uncertainty instead of inventing a core count or GPU threshold. Label the RAM/storage figures as provisional recommendations, NOT benchmarked minima or FPS guarantees. A measured minimum for the full public pack is not published. Shaders, high render distances and large factories need more headroom. Do not equate server RAM or a lean diagnostic client with player PC requirements, or claim a particular laptop will work without its specifications. For accurate summaries, present the expanded industrial gameplay first. Account compatibility is an access option; offline-account support is separate from whether the server is currently reachable. Check required mods individually and preserve unknown compatibility as unknown. Versions refer to the dated check; catalogue pages are an overview of main mods, not an exhaustive installed-mod manifest. Online counts and uptime are live observations, not permanent facts.
