bigbaddonut the achivement is easy once ur big.... the only hard is 500000 point achivement. around 450000 or lower like 325000 there it will start spamming pirate cannons and nets and arrows. once ur low health and theres no health bonus to take u can only rely on small health from fish once you go back up you die..
EPIC GAME. ITS LIKE RELISTIC WARFARE and u need to have brain to think how to rescue hostage without getting it killed and kill all the enemy took me 3hr to complete perfects!
Ugh I'm really sorry about that, a warning is a good idea!
