How To Perform Combos :
There are 3 types of combos, 3, 4, and 5 hit combos. They are labeled huge, mega and super. the combinations for these are relative, meaning they can be performed starting from any side, right, left, up or down. For example a 3 hit combo can be up-down-up, or the same one mirrored down-up-down, or starting from right or left: right-left-right or left-right-left. The same goes for 4 and 5 hit combos so I'll only give the combination starting from up, but you can start anywhere and adjust your combination.
3-hit combo :
up - down - up
down - up - down
right - left- right
left - right - left
4-hit combo:
up-up-down-down
down-down-up-up
right-right-left-left
left-left-right-right
5-hit combo:
up-down-left-right-up
If you perform all 3 combos in one fight, you will get an achievement.
