A mechanic new to MvC3 . X-Factor is activated by pressing all 4 attack buttons at once. When X-Factor is active, your point character regains "red life" at an extremely rapid rate, your character is substantially sped up, and both normal and "chip" damage are greatly increased. In addition, on activation, all of your cooldowns are reset (see XFC below). The potency and duration of X-Factor is dependent on the number of teammates you have remaining. If all 3 of your characters are alive, then you get a level 1 X-Factor. If you're down to your last character, you get a level 3 X-Factor which substantially increases all attributes of X Factor. YOU CAN ONLY USE IT ONCE PER ROUND!
