Each time you're ready to jump into your flight suit, you'll choose your mission, one of the six unlockable suits of armor, and which upgrades you'd like to use. See, rather than have you earn money from your battles like the PS3/360 version of Iron Man does, this incarnation of the game upgrades your gear--repulsor, ballistics, explosives and armor--based on how much you use them. If you're like me, you'll find yourself hovering around levels and blasting evildoers with your repulsors the most, and in no time, you'll have taken your laser gauntlet from the most basic tech (fast but weak) to the mega-awesome Optimal Beam Damage. Of course, this applies to whichever device you're using, and a few will actually upgrade to the point where you need to choose which option you'll be using in battle (i.e. which type of missile you want to launch into some dude's face).
