RE: The official Super Smash Bros Brawl thread.
to avoid the red flashes press the R button to defend, then when the waves start to come out quick turn either back or forth (holding the R button tap FWD or BK)...try to time it right so you can dodge the first, then wait a sec and dodge the second, wait a sec again and dodge the last. i haven´t done the 15 min brawl, i was 2 mins away to achieve it... but i´ve managed to beat 15 in cruel melee, using kirby...just let those suckers fall while you fly.
