There’s a lot of basic movement stuff missing- like crouch, prone, or Zelda-style wall-climbing. There are a lot of purported “movement” packs out there, but only “Advanced Locomotion System” (ALS) is able to demonstrate in a video that the animations work together to create a functional controller. Lo-and-behold, ALS is the most-rated (and I assume most-purchased) asset on the marketplace.
