Look over the shoulders of people playing Soulcalibur V and you’ll see something worrying. Something that will make you think Namco’s glorious new fighter is, quite frankly, a bit Bethesda’d. At the end of a round, the victor often judders uncontrollably, like a bugged disco android in meltdown. But everything is fine. The reality is that the winner is hammering X so frantically it resembles an attack of the collywobbles. It’s an involuntary action brought on by the urge to start the next round without undue delay – in medical parlance it’s known as the Soulcalibur Shakes.
