If you had asked me a week ago whether I'd ever give a rail shooter a perfect score during my game reviewing career, I would have said not to bet on it -- a game in this genre has to do a lot to make up for the player's lack of exploratory freedom, after all, and I'd played very few that managed such a feat. Then "Battle Group" came along.
Aye, if you pass up Black Pearl Games' and Lakoo's "Pirate Gunner" you be missing out on one o' the finest action puzzle experiences in the App Store Sea. Arrr!
