Let me give you a brief overview of the egg sequencer system, which you'll find on the right side of the space anomaly (this location was specifically chosen because it's a hub for experimental technology). The device lets you tinker with companion eggs through four fascinating modification slots, and understanding each one will help you create exactly the companion you're looking for.

The growth hormone slot is your size controller - this works because different elements interact with the genetic structure differently (oxygen makes things bigger while ferrite dust shrinks them). The gene splitter handles body features, though i should mention it's a bit unpredictable because the genetic combinations are incredibly complex. The dye injector is pretty straightforward for colors, and the neural calibrator shapes personality traits like aggression or gentleness (which actually affects how your companion interacts with the environment).

When it comes to priorities, i'd suggest focusing on size modifications first, since this has the most noticeable impact on your gameplay experience. Color changes through the dye injector are also reliable and can make your companion truly unique (try using chromatic metals for some interesting results). The neural calibrator deserves attention if you're planning to use your companion for specific roles - gentle giants make great exploration partners, while more aggressive companions excel at protection. The gene splitter is more of a wild card, but that's part of what makes it exciting. Remember that you can always experiment multiple times before hatching, which gives you room to really perfect your companion's traits.
