Long-time TouchArcade favorite Harbor Master [$1.99 / Free] was recently updated to add complete Game Center support, transitioning away from Imangi Studio’s own proprietary scoring system. Online scoring mostly remains the same, aside from being piped through Game Center now. What Harbor Master didn’t have before is achievements, and now there are 38 in all for achievement fanatics to farm up. These achievements range from being simply score based to difficult challenges such as reaching a certain score on Pirate Passage without killing any pirates.

In addition, the controversial rewind feature from Harbor Master HD [Free] has made it over to the iPhone version of the game. Unlike the iPad game, these rewinds aren’t IAP, and are simply earned by playing the game.

If you haven’t had Harbor Master on your device in a while, this is the perfect opportunity to give the game a spin as shooting for the achievements gives a fantastically tangible goal to a previously endless game. Similarly, if you haven’t yet given Harbor Master a try, it’s really worth at least checking out a free version of the game especially if you haven’t dabbled in the chaos management genre in a while.
