There is a new world record for Dark Souls II (Vanilla, PlayStation 3, Xbox 360, Steam). For this particular speed run, it is any percent and glitches are allowed for the shortest time possible. Completion runs and other styles of speedrunning are up on YouTube as well, but this one style is the most interesting to watch.
I honestly wish I could say I could do the same, but I know I can’t. So, watch someone else do it themselves!
