Mega Man Xtreme 2 offers an "Xtreme Mode", a higher difficulty setting designed to challenge even the most seasoned Mega Man players. This mode likely increases enemy difficulty, adjusts boss health, or introduces additional obstacles throughout the stages.  It caters to players seeking a greater challenge beyond the standard gameplay experience.  The implementation of such a mode demonstrates Capcom's understanding and willingness to cater to a range of player skill levels within their Mega Man titles on the Game Boy Color.
