With all these treasures around, one must learn to defend what's theirs. What if it's in someone else's pockets? Take this class of RAIDJUTSU and get back in the game! Your friends will never know what hit them.
First, we have the efficient PUSH of death. Get behind your friends when they're close to a ledge, and push them into the waters to empty their pockets - button (A).
Then, we have the classic TAKEDOWN. Grab your friends by holding (X) or (Y) button to take'em down and steal one of their treasures. Make sure to surprise them, because if they guess and hold the same attack button, they'll do a COUNTER-TAKEDOWN on you.
The advance LADDER TAKEDOWN is sometimes a rather desperate move. Drop down from a ladder and hold the (A) button while you pass by a friend who was climbing under you.
And if none of this kung-fu moves help, hold (B) button to charge your shotgun, aim well, and release!
But remember, in the end, friends or foes, you're all in the same boat!
