Chris Buffa (Modojo): If you enjoy aerial combat games and prefer downloading stuff for free, play Bombshells: Hell's Belles, the newest iOS and Android title from Glu. Set within the same universe as the hugely successful Gun Bros, this intense third-person shooter stars unflappable femme fatales who take to the skies to thwart the evil schemes of their arch nemesis, the dastardly T.O.O.L. organization. You'll need to grind and/or splurge via in-app purchase to acquire the best gear, but by and large, the game satisfies. Now if only multiplayer would work.
