Factorio 2.1 is live, bringing quality-of-life changes and smaller features Wube had wanted to include in 2.0. The update became stable on October 23, 2026, after experimental testing began in June. After 14 years of development, Wube calls it the game’s final major update, though bug fixes and work on modding features and platform compatibility will continue.
Before loading a long-running factory, keep a separate backup of its save and blueprints. Older saves will load in 2.1, but circuit-network changes may disrupt existing designs. Once converted, saves and blueprints cannot be downgraded to 2.0. Wube recommends backups, especially for players relying on mods that have not been updated, in its Friday Facts post.
Rockets can now carry multiple item types in one launch. In Space Age, platforms can transfer goods to one another in orbit and automatically import items from available locations. Asteroid collision damage now depends on an asteroid’s remaining health rather than its speed, while platform drag is based on mass instead of width.
A constructable unloading bay attaches to landing pads, letting inserters move arriving cargo onto belts or into chests and trains. Elevated rails can cross cargo bays, and land mines can serve as tripwires or enemy detectors. A new rendering system also makes it easier to connect pumps to rail fluid wagons.
Base defense changes, too. Biter expansion groups now scale with evolution, nests appear in more natural locations, and biters can expand their territory even if players have not explored the map early. Wube’s goal is to make clearing nests a more meaningful challenge than dealing with lots of tiny nests.
Elsewhere, 2.1 restores fluid-mixing prevention and lets Space Age players disable the Quality mechanic without giving up the expansion. Assembling machines, oil refineries, rocket silos, and heat exchangers get updated graphics. Pumpjacks and burner mining drills can now be flipped, and the update adds native ARM64 Linux support.
Factorio has more than 234,000 positive Steam reviews and a 98% Overwhelmingly Positive rating. Wube has also kept the game off sale, a policy the developers explained in a 2016 forum post.
