Well, depends on which mission you're referring to.
On Survivor, the missiles are on the second level in the same area as the nasty Metroids. Instead of going out into the big open area at the start, go into the alcove and up a few ramps. The missiles are on top of some tanks.
As for Regulator, missiles are found in the room before the boss battle.
To switch weapons, merely tap the missile icon on the touch screen to shift. (You need to have actually found the missiles, though.)
Hope my directions didn't confuse you too terribly. |
