Factorio

Wube Software has confirmed that Factorio version 2.1 will be the final major content update for the factory simulation game. The announcement moves the game from active development into long-term support. Version 2.1 focuses on quality-of-life improvements, bug fixes, and modding enhancements rather than new planets, enemies, or research trees. A closed beta begins soon, with a test version expected by the end of June and a full release after summer.

The same update cycle includes a change to how the game's quality mechanic is understood. A computer science graduate student reverse-engineered the pseudo-random number generator behind quality rolls. Based on a 2014 tip from a former developer, he confirmed the game uses taus88, three combined linear feedback shift registers. By recycling repair packs in Factorio 2.0, he observed 88 bits of output over 44 operations, reconstructed the generator's internal state, and used in-game circuits to predict future quality rolls. He also automated skipping unfavorable random numbers to reach Legendary results.

The two developments point in opposite directions for players: the development team is winding down major additions, while parts of the community keep pushing against the game's systems. The documentation frames quality as a matter of statistics in mass production. The reverse-engineering work turns that resource grind into a scheduling problem.
