MTS - Same Factorio seed, up to 20 private worlds — each team races their own copy. Independent research, separate planets, zero resource conflicts. Buddy-join with friends, ally via mutual friendship, spectate rivals with live per-player follow cams. First-to-research announcements and per-team clocks drive fair speedruns. Common terrain mods (dangOreus, VoidBlock, Alien Biomes) work out of the box.
Scenarios, maps, and puzzles.
