The only thing that really needs to be said about Dark Souls II is that it's more of the same. The game keeps everything which worked in the original. It remains hard as nails, improves and expands upon previous aspects without ever losing sight of what it needs to be, and is an all around solid title. The only real failings come from its increasingly overblown reputation and the various communities which have built up around it. If you like hard as nails combat and enjoy bleak, dark, moody settings then you'll be right at home here.
Still, you're probably not going to be quite satisfied with just that. So, let's examine these points in further detail. Just to give warning though, this is mostly going to be a review for people who played the original.
The game's plot is about as minimalist as the original. Playing as an unnamed undead warrior, you travel the lands in search of a cure to your affliction and a potential end to the darkness now choking the realm. This time you are travelling the lands of Drangleic after awakening in the town of Majula. a small rural haven for travelers and lost souls. After some helpful recaps of the previous plot explained by listening in to a few of the local downtrodden folk, you head out to fight some monsters.
