plants can be scanned,it's just sometimes challenging BECAUSE they're dangerous. I don't think any of the creatures are going to be dangerous, at least not for the demo.
Okay. It feels a little weird that only plants would be dangerous, so I'm personally hoping for some dangerous critters too. Looking forward to the demo regardless.
its just kind of a way to maintain consistency. creatures can move and dig and do all sorts of things so they can use those actions to evade you--but with plants they cant do a whole lot, so they compensate by defending themselves with deadly weapons
