Earlier today Konami released a new video that details all of the different game mechanics that players will be using when Blades of Time is released next year. There is of course your standard fighting with a sword and gun but also you can see a number of other features as well, namely the time-rewind that players will be using.
Time-rewind is going to be used for puzzle mechanics as well as for combat, as you can see in the trailer below. The time-rewind ability allows players to make clones of Ayumi and allow her to fight alongside herself against stronger enemies such as a boss. While Gaijin Entertainment is still at the helm for Blades of Time, it is not a sequel to X-Blades but more of a completely separate title with the relatively same looking and same named heroine Ayumi.
