"Yar! If ye ever had the druthers for engaging sea-monsters and menacing ships filled with scurvy pirates, this be the game for ye! Seafight is an in-browser, free-to-play, point-and-click shooter by developer Bigpoint Games in which you attempt to become the most dangerous object in the water to both enemies and players alike."
"You start with the weakest vessel and work your way up the ladder, upgrading your weapons, ammunition, and crew as you progress. Like with most free-to-play games, there is always an option of spending actual money to buy perks and new gear, but it's rather unnecessary. Some gear is only obtainable during special events, but is much better than what you can get in the store through normal purchase. Be sure to check out the screen shots and cheers!"
