Back in January of last year, Irrational Games announced that BioShock Infinite would have a hardcore 1999 Mode, which would make players pick a specialization that locks them into a set framework of powers and skills. There'd be no going back on those choices and death would be permanent. Back then, Irrational said that the only way to unlock 1999 Mode would be to finish BioShock Infinite for the first time.
But, as the game goes on sale world wide today, the developer is revealing that all you need to do to go straight to the hard stuff is used the beloved Konami Code at the main menu. Here are the inputs:
For PC or Xbox 360: Up, Up, Down, Down, Left, Right, Left, Right, B, A
For PS3: Up, Up, Down, Down, Left, Right, Left, Right, O, X
You'll get a notification that the unlock worked and then you proceed to getting your butt kicked by guys in breeches and bowler hats. Enjoy!
