When it comes to SN2 I’m not sure how many years after the events of SN1 things are taking place, or if these two explorations left around the same time (if they did ignore this suggestion) but if we are 50 years later the exploration tech should show major advancements as the player upgrades their base and inventory. I think we are seeing this with the biomods, and some of the habitat builder features, but when it comes to tools and tech that gets placed inside of bases things are very similar to SN1. Maybe the ability to connect some new tech discoveries from Ryleys interaction with the Architects tech or similar to how biomods combine human dna with creatures on the planet, maybe there could be bio-tech tool where the physical tech itself could take on some of the biological advantages found in the environment. A bioluminescent flashlight that doesn’t need recharging for example, or a Plyon multitool that shocks fish, etc…
