The 1.4 development cycle significantly expanded the game’s scope through the "Biotech" mechanics. Key features available in this version include:
The introduction of germline genes (inherited) and xenogenes (implanted) allows for the creation of specialized human subspecies, essentially treating genetics as biological bionics. RimWorld.v1.4.3510.zip
Players can control their own swarms of semi-autonomous mechanoids, shifting the gameplay from purely managing human needs to managing a complex industrial machine. RimWorld.v1.4.3510.zip
