Slave Zero X is action packed, challenging, visually striking, and highly replayable for the dedicated player, however not so much for those seeking a casual experience. The way I feel the game falls short is that it fails to guide the player early on. Unlike the fighting games Slave Zero X takes heavy gameplay inspirations from, the game does not provide any sort of combo moves lists to help the player learn or improve at the game beyond a basic tutorial slideshow covering basic mechanics. The game also fails to clearly outline or demonstrate to the player what determines chapter and combat rankings and what the game actually considers "good" play. Many players like me who enjoy dedicating themselves to a game, practicing and learning encounters to overcome a challenge, will most likely enjoy Slave Zero X quite a lot, but I cannot say that this game is for everyone.
