5. In the first "BioShock" game, Jack, the protagonist, begins the game with the Wrench.  What is the first weapon of "BioShock 2"?
From Quiz BioShock 2
Answer: 
Drill
Playing the mysterious Subject Delta in this visit to Rapture, your first weapon is the characteristic drill attached to a Big Daddy's arm-- after all, you are a Big Daddy prototype.  The Drill requires fuel in order to be charged and spun; you can also beat enemies with it using a strike attack.  This strike can, in turn, be charged up by Gene Tonics (one, for example, gives it the power of frost).  The drill is a fairly strong close-combat weapon.  Keep in mind, however, that it's not effective against groups of enemies or foes with stronger armor.
