A major feature of the update
Also scheduled for the update are four tournament modes: Daily Tournaments (Mon. through Fri.), Super Saturdays, Simulation Sundays, and the Global Cup (a grueling, 512-man event which takes two weeks to complete). Rumor has it that, for a fortnight, the winner gets to sit high upon a tower crafted from the bones of their fallen competitors, and declare supreme dominance over all of Xbox Live. Let us all hope for a merciful and benevolent ruler.

Update: Apparently, the newly renovated Cat and Mouse mode was late for the morning train, and will not be featured on todays update. However, a Bizarre Creations employee has assured us that the new mode will be "rolled out in a separate update in a few weeks."
