i got this at toys 'r' us for $15 because of their high prices. but i think it was kinda worth it... i guess...

its similar to many battle packs but you have the good guys and bad guys. i personally think the minifigs blind the people of the weirdness of this set. the cannon is a misssed oppurtunity to have made a decent $30 set because of the size it is in real scale.
