Irrational has introduced a new mode to BioShock: Infinite, which it is calling '1999' mode. From what we understand it does away with on-the-go upgrades, providing a more harsh play-time.Says Ken Levine, "We want to give our oldest and most committed fans an option to go back to our roots.
"In 1999 Mode, gamers face more of the permanent consequences of their gameplay decisions. In BioShock Infinite, gamers will have to sweat out the results of their actions. In addition, 1999 Mode will demand that players pick specialisations, and focus on them.
“I’m an old school gamer. We wanted to make sure we were taking into account the play styles of gamers like me. 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. 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.”
So, a hardcore mode.
