From the picture you can't tell much detail really about it, but it's an awesome little set. In the captains quirters there's a table that you can flip to the side and drop skulls down it which come out the front. and over by the treasure chest there's a hidden trap. so you better watch out! when the fight reaches the bidge, pull out the pin and it will turn over knocking everyone off! One of my favorite parts would have to be the real working cannon on top. I used to have one but lost it, so I'm glad to have one back! It comes with 6 minifigures: Pirate Captain, Pirate Wench, Pirate, Soldier Captain, Soldier and a Skeleton Captain. All figures are printed on back, except skeleton. I do think that it's over priced for what you get, but that's ok. It cost $39.99 and I bought it at Toys 'R' Us.
LEGO Pirates: Cannon Battle (6239)
This set is a battle between a soldier and a pirate. (personally, if the soldier misses with his gun, I think the pirate will win) Cannon actually fires. New flame piece is seen in this set, and also the new telescope piece. (It's the gold piece used on the stick with fire) This set cost $5.99 and I bought it at Toys 'R' Us.
LEGO Pirates Soldier's Arsenal (8396)
This set is great if you're building an army of these kind. (the soldiers) Also, it features (that I know of) a new piece holding the guns and sword. It's a 1x1x1 clip. I haven't seen this before, so I assume it's new. This set cost $3.99 (not possitive on it) and I bought it at Toys 'R' Us.
LEGO Pirates Pirate Survival (8397)
This set is useful in collecting alot of pirates (although they'll all be the same one). It features the new fish piece. His hat is dark green (new color for that hat) features a square crate and two jewels. This set cost $3.99 (not possitive on it) and I bought it at Toys 'R' Us.
I hope to have more pictures up of the shipwreck one soon. So make sure to come back!
