This was already mentioned in the NEWS section of The Leaderboard but in case anyone wanted to discuss about this Gameplay Shake-Up to KOFXV on the forums I made a post about it here as well.

On January 30th SNK will be Updating KOFXV and adding in a New Offensive Gameplay Mechanic called "Advance Strike"! This will significantly change how the Overall Gameplay is for KOFXV so please take note if we once again make changes to The Leaderboard Listings for all Runs prior to This New Update as being a separate Listing Sub-Category Post-Update, much like We've done in the past with significant Updates! 🤔

For more detailed explanations on The Advance Strike Mechanic please refer to the Video Example Below:
