Dark Souls II is such a long game, it has so much content that it's easy to forget what you did, and the ridiculous amount of enemies you slashed, scudded and backstabbed. What this Dark Souls II video does is interesting: it records in stabs and attacks, creates a rhythm, but also takes you through almost the entire game. In six short minutes.
It also serves as a reminder of how good Dark Souls II's enemy design was -- just the variety of it.
It goes without saying there are spoilers, but if you're a fan of the Souls series, this is a must watch.
