Easy Way to Beat Apocolpyse
     The  best  person  to  beat  Apocolpyse  is to Storm and Magneto,
Chun-Li  and  Cyclops.  Whenever  you  begin to fight with Chun-Li and
Cyclops  super  jump  and  lighting kick his hand then when your power
gets  up  to three preform the team super move. Do the same thing with
Storm  but do the Double Typhoon until it gets to level three then the
team super move.

Gambit's Monstrous Combo
     First have your super bar at level 3, and of course be playing as
Gambit. Then, do Gambit's Royal Flush super. If it connects, cancel it
after  at  least the 33rd hit while the super is still going on with a
second  Royal  Flush.  Then, when the combo counter reads at least 62,
cancel  the second Royal Flush while it is still going on with a third
Royal Flush. You will have 99+ hits! (Although the combo counter stops
at  99.)  Note that this will work only if the opponent is standing on
the  ground. If he/she is slightly in the air, the cards Gambit throws
will not hit the opponent as much times.
