It is always nice to see the Souls formula in a different setting, with a totally different aesthetics. The game is not particularly hard (by far, the hardest part is finding your way around the Cathedral of Sacred Blood), the enemy variety is limited, and the fan service is quite distracting, but it offers a good deal of nice things, big and small. Changing builds on the fly is the best addition to the Souls formula Code Vein implements and it's quite welcome. The story is very anime, so don't expect much, but expect to be sucked in.
