One of the biggest remaining pieces of canon stat material was creatures — all the assorted aliens and critters and nasty things that pop up in various books. After some schema twiddling and a lot of data entry, they’re all there: the Bestiary is now much deeper, and the remaining smart animals finally have their full skill blocks, to boot.
One problem, however, is that the automatic Threat Rating calculator is bad at weighting many of the unique skills that make exsurgents and creatures so dangerous. Nanoswarms, for example, don’t strike it as very dangerous because they don’t carry guns and armor — nevermind the fact that they’re basically invulnerable to damage and can disassemble anything you throw at them. It’s not a huge deal, but it’s kicking around in the back of my head as other game-related enhancements get some attention.
