Travellers are now able to adopt the creatures they encounter and form close bonds with them. They will travel side-by-side with you as you adventure through the universe both as a friend and as a valuable aide on your voyage. Train them to scan for resources, mark out hazards, provide light, hunt dangerous fauna, find settlements, excavate buried treasure or even mine for materials with their own shoulder-mounted mining lasers.
If properly nurtured, your companion will lay eggs which can be collected and incubated. Watch in wonder as the new-borns hatch and grow from babies to full-grown adults! Or use the Space Anomaly’s new Egg Sequencer to genetically modify your companion’s eggs into ever-wilder species.
I completely missed this although how much use it will be in game, I'm not so sure.
