Ninja Gaiden Sigma 2 has seen a number of revisions throughout it's Campaign, but for it's tidying and polish, it's essentially the same game it was back in 2008, and suffers from many of the same flaws. The camera can be infuriatingly ignorant of the players' wishes, often requiring you to engage an unknown enemy without a line-of-sight. The control system can occasionally feel loose, calling for unnecessary retries during occasional stretches of tricky acrobatics, and the numerous areas where the difficulty inexplicably ramps-up will deter many before reaching the closing stages. In addition, it must be noted that the PlayStation 3 release does frequently suffer from some incredibly long loading delays.
