Keen’s figures are 6 GB as the minimum and 10 GB as recommended. | Feature | **Small faction** Up to 4 players | Recommended **Community** Up to 16 players | **Large** 16+ players or big worlds | | --- | --- | --- | --- | | Memory (RAM)Working memory for the world, the players and every mod.

Large moving grids lower the sim speed the most. ## Worlds, limits, mods and crossplay Keep a busy world fast and fair for everyone on it. ### Survival or creative Start a new world from a scenario or upload your own save, then set inventory size, assembler speed and more. ### PCU and block limits Limits are off by default. Set BlockLimitsEnabled per player or per faction, with a TotalPCU, to keep the sim speed up. ### Steam Workshop and mod.io Players download the mods a server needs when they join; the first time can take a while. ### Crossplay PC, Xbox and PlayStation players play together through Epic Online Services; crossplay servers use mod.io mods only. ### Scripts and plugins In-game scripts are on by default. Mods with code run on a dedicated server only when the code is server-side. ### Auto-saves and cleanup The world saves every 5 minutes by default, and trash removal clears debris and leftover grids. ## Set up your Space Engineers server Four steps to your faction’s first launch. 1. ### Pick size and world Use the table above, then pick a scenario or bring your own save. 2. ### Pick a location Choose the one closest to your faction from our 20 game server locations. 3. ### Set limits and mods Set MaxPlayers, block and PCU limits, add your mods and choose whether console players may join. 4. ### Join the server Open Join Game and find the server in the Servers tab, or use Direct Connect with the address and port. ## Other game servers you might like [See every game](https://hyperdc.com/game-server-hosting) ### Satisfactory Co-op factories with Steam and Epic crossplay and your own saves.

Space Engineers has crossplay between PC, Xbox and PlayStation through Epic Online Services, and a dedicated server set up for crossplay accepts console players. Crossplay servers can only use mod.io mods. ### How many players can a server hold? MaxPlayers is 4 by default, and the dedicated server tool offers up to 64. More players and grids need a faster CPU to keep the sim speed up. ### What hardware does Keen recommend? For the dedicated server: at least 3.2 GHz, 3 logical cores and 6 GB of memory; recommended are 4.5 GHz, 3 logical cores and 10 GB. Single-core speed matters most. ### Why is my sim speed low? Usually because of large moving grids and physics. Convert parked ships to stations, clear debris, keep trash removal on and set PCU limits. ### How do I set block limits? BlockLimitsEnabled is NONE by default. Choose GLOBALLY, PER\_FACTION or PER\_PLAYER, and set TotalPCU and MaxBlocksPerPlayer. ### Which mods can I use? Steam Workshop and mod.io mods; players download them when they join. On crossplay servers only mod.io mods work, and mods with code run only when their code is server-side. ### Which port does the server use? 27016/UDP by default, and you can change it. The optional Remote API listens on port 8080. ### Does Space Engineers 2 have dedicated servers? Not yet. Space Engineers 2 is in early access; Keen plans player-hosted co-op first and dedicated servers later. This page is for Space Engineers. ### How do players join? Open Join Game and pick the server in the Servers tab, or use Direct Connect with the address. The Favorites and History tabs help players find it again. ### How often does the world save? Every 5 minutes by default (AutoSaveInMinutes). Back up the save before big changes or mod updates. ## Ready to build in orbit?
