Space is big. Really big. You may think it's a long way down to the chemist's, but that's just peanuts compared to space. And with all that space, there are plenty of alien species inhabiting the various planets, moons, and asteroids. You get a whole bunch more of them for your Starfinder games in Alien Archive 3. In this article, we get a look at some of them, including new playable races.
From the post:
Starfinder’s newest creature compendium comes packed with more than 100 stat blocks, including half a dozen new creatures native to the hyperspace plane of the Drift. But there are plenty of more worldly foes, too. In Starfinder, even seemingly innocuous things can become deadly, such as the ferromagnetic ooze, seen here engulfing our unfortunate mechanic, Quig, as his trusty drone, Scout, attempts to give him a lift without getting pulled in too.
