Downloads of the repository and the source code in releases require the file map_selection.sample.lua to be renamed to map_selection.lua. Release assets named for maps have this file built in.


RedMew is a Factorio community that hosts custom servers, maps in different shapes and sizes, scripted scenarios and modded servers. All of the games hosted are available to the public and our community is meant for players of all skill levels and experience. You can find out servers by searching for "RedMew" in the multiplayer lobby.
