Prometheus offers a Space Engineers server with a player market documented by the project. Players can post offers and orders with unit prices, search for items and buy listings; sellers pay the 10% tax. The !ore and !ingots commands show where to find ores and which factories process them, while !grids list locates owned builds by GPS. When simulation speed is low, the guide provides for a restart vote approved by more than half the players, followed by a restart within five minutes.
