Bombshells: Hell's Belles is a combat flight simulator game. Inescapable in-app purchases that are the hallmark of freemium games are present here too, even though, as of this writing, the application itself is not free to download. In this game, you use machine guns and missiles to take down "T.O.O.L." planes and structures on a variety of sequential missions.
Once chassis and weapons have been selected at the hangar and the mission chosen, the fight is on. An energy gauge is used for aerial maneuvers and refills automatically over time; the health bar does not. For increased weapon damage, increased speed, unlimited energy and a boost of health, it's possible to collect power-ups, which are scattered around the scene.
Energy beams which are never adequately explained and sniper fire from afar complement the enemy's share of missiles and rapid gunfire. Your weapons and your enemies' may both be imbued with "elemental" properties that cause dysfunction upon impact.
Sam's Protip: Something's weird about mouse control - it takes a while to rotate, and once you do it's hard to stop spinning. I'd stick to keyboard input if I were you.
