BioShock Infinite introduced the difficult 1999 mode for the main game. When BioShock Infinite: Burial at Sea - Episode 2 comes out on March 25, Irrational Games will add a 1998 mode.


This mode will challenge players to beat the DLC using only non-lethal means.
“In Burial at Sea – Episode Two we put a focus on balance and stealth mechanics,” said Ken Levine, creative director of Irrational Games. “As we were developing this new style of gameplay, we started to see people self-impose non-lethal playthrough’s. Given the fan reception of 1999 Mode, we thought it would be cool to give them another way to play Burial at Sea that challenged their mastery of stealth tools.”
