Hint :
Hint: Easy survival mode:
After unlocking the EX Options, go to the "Extra Option" and set "Life Gauge" to "No Damage" and "Groove Gauge" to "Infinity". You will be able to blast through all 46 characters in no time.
Hint: Easy Boss challenge mode:
Choose a good fighter such as Ken or Ryu. When you are facing the last Boss, if you are losing by one round and there is not a lot of power remaining, press Start on controller two and repeat until you win.
Hint: 99 hit combo:
Once everything is unlocked, set your Super Bar to "Infinite" in extra options mode. Select Rock in any mode and choose the P Groove (Custom Combo Groove). When you fight, press HP + HK for Custom Combo, trap your opponent in the corner, and do the Rising Tackle. When your move is being executed hold Down. When you touch the ground, press Up + HP to execute another Rising Tackle. Repeat this until you get a 99 hit combo or your opponent loses. Note: This can also be done with Terry.
Hint: Getting a Finest KO:
Beat up your opponent until his/her life is low enough to finish them off with a special KO. Stand near your opponent and wait for them to taunt you. Then, do the special move and you will get a finest KO. You also have to either beat the mini-Boss, or receive 1500 GPS before you finish the final round in Osaka to get to God Rugal.
