If the player finishes the game a second time, a third costume is unlocked. One is the Army Type, and the other is the Battle Type. If the player can finish the original game once, Regina is given two alternate costumes to wear instead of her typical black body-suit. Fires small torpedoes, and is capable of destroying hard materials.
Over the course of the first game, Regina finds herself with three weapons to choose from: a Glock 34 automatic pistol (upgradeable and modifiable with sights), a Franchi PA3 12 gauge shotgun (upgradeable and modifiable with stocks) and a HK69A1 40mm Grenade Gun (also upgradeable).
