Bolt from the Blue trophy

Bolt from the Blue is an Achievement/Trophy in BioShock Infinite. The Achievement is worth 25 Gamerscore and the Trophy is silver.

Description: Killed 5 enemies with a headshot while riding a Sky-Line.


The player will have to kill 5 enemies with a headshot while riding the Sky-Line.



A Sky-Line.

  • Any weapon that one can perform a headshot with will do.
  • Vigors cannot be used on the Sky-Line and thus can not be used towards this Achievement/Trophy.
  • Sky-Lines that the player can use first appear in Comstock Center Rooftops.
  • Killing enemies from a Freight Hook will not count towards this Achievement/Trophy.
  • Sky-Line Strikes will not count towards this Achievement/Trophy.
  • The final blow has to be a headshot for it to count towards this Achievement/Trophy, meaning that the player can damage the enemy by other means.


  • Use weapons that are zoomable, as headshots usually require great accuracy. The most efficient weapon to use is the Sniper Rifle, but any weapon that provides a steady aim will do, such as the Machine Gun.
  • The player can slow themselves down on the Sky-Line, making getting the headshots much easier.
  • Human enemies (ex. Soldiers) are the easiest to kill.
  • Play on the Easy difficulty setting to kill enemies with less damage.
  • The player can abuse the checkpoints in order to get this Achievement/Trophy. Find a location with enemies and a Sky-Line and simply kill everyone with headshots from the Sky-Line and reload your last save to start again. A great place for this is after leaving the Hall of Heroes towards the Patriot's Pavilion.

Behind the ScenesEdit
