Arr! for Mac

From Winterborn Software:

Get ready for pirate ship combat! The object of Arr! is simple; collect as many doubloons as you can by destroying enemy ships. But don't forget about a pirate's worst enemy (outside of scurvy), the clock! With each successful raid, the other territories become more aware of your reputation, and you will have less time to complete your raid. Will you go down in history as another Blackbeard, or will you walk the plank down to Davy Jones's locker? Send up the Jolly Roger and heave away!
Features:
* Classic arcade action * Three different pirate ships to command * Tons of power ups * Single player or two player head-to-head modes * Small download (< 2MB) with nothing to install
