"I'm an old school gamer. We wanted to make sure we were taking into account the play styles of gamers like me," said Irrational's creative director Ken Levine. "So we went straight to the horse's mouth by asking them, on our website, a series of questions about how they play our games."
Levine continued, "94.6 percent of respondents indicated that upgrade choices enhanced their BioShock gameplay experience; however, 56.8 percent indicated that being required to make permanent decisions about their character would have made the game even better."
The 1999 Mode will include unnamed tweaks and features that won't exist in the standard BioSchock Infinite experience. It will also "feature demanding weapon, power, and health management," along with a "Game Over" screen if the player lacks the resources for a respawn. The company is unlikely to cover incidental damages to property caused by playing 1999 Mode.
