Do I need any of the Alien Archives to play these adventures?

Hello everybody
As put in the title: do I need any of the Alien Archives to play Planet Fall?
I tried to figure it out by myself but I find no answer.

Thank you for your help

Archives of Nethys has the aliens if that's what you're needing.

Short answer is yes, the AP references creatures from all four Alien Archives. Longer answer is that you can use the Archives of Nethys site to fill in gaps.

Not all of the stat blocks are in the AP volumes. A couple of critters are something with a graft, meaning you might need a couple of books to construct a full stat block.

Given that the Starfinder SRD makes public all of the Alien Archives, you don't HAVE to purchase the books. You might find them useful, but so long as you have access to the internet, you don't need them.
