X Challenge

X Challenge is a brand new mode that will be exclusive to the Mega Man X Legacy Collection and Mega Man X Legacy Collection 2 which allows the player to simultaneously fight two bosses (Mavericks or Fortress Bosses) from the SNES and/or PS1 X Games (X1-X6) using X.

In addition, a brand new armor will be exclusive to the mode which players have option of using X with or without it equipped. Each challenge will have 9 possible special weapons from the six X titles which players will be able to choose between 3 of them.

Much like with the Challenges from Mega Man Legacy Collection and Mega Man Legacy Collection 2, each challenge has a clock system and a leaderboard system for players to compete by completing the challenges as quick as possible and within the time limit (which is now done in reverse unlike before). Unlike with the earlier Legacy Collections however, players only have a limited amount of lives and start with 2 extra lives in reserve when beginning the challenge.
