One of the new features that PS Vita and PS4 action game Toukiden: Kiwami will contain compared to the original is the Endless Mission mode.
Judging by the trailer this is basically a never-ending boss rush. The mode appears to support multiplayer and the brief trailer calls it “The Ultimate Challenge”. Challenging it may very well be but hopefully there are also some more incentives to give the mode a whirl, like equipment or what have you.
See the trailer below and grab Toukiden: Kiwami on March 31st.
