Easy done on the first combat challenge. Here some tips to avoid be hit.
First and second wave are really easy, just avoid extreme combos and use Ground Pound (RT+Y) only if other thugs are far enough.
3rd and 4th wave:
- if two thugs come close at the same time, use quick batrang to stun one and hit the other with X
- use Y to counter just when you can see the lighting on the head. Hit Y just one time, or you'll be exposed to the attacks
- Where the combo counter became yellow, you can use instant KO. You're untouchable for a few second, so you can hit another after the KO is done: choose the farest one, no matter the distance (Batman will reach him anyway)
- Use RT+Y only where there's 2 or 3 guys left
- If you're facing an ennemy and another guy is hitting you, use A or double A and restart from a safer position (ex. X, X, A, A, quick LT, Y, X...)
- After a combo or an istant KO you'll probably have to face a couple or even 3 guys at the same time. Use Cape Stun (B) to gain precious time.
If you're be hitten... restart the challenge and resist the wish to break the controller *LOL*
