Irrational Games announces a new stealthy, nonlethal 1998 mode coming to BioShock Infinite in the upcoming Burial at Sea – Episode Two DLC for the shooter prequel. "In Burial at Sea – Episode Two we put a focus on balance and stealth mechanics," explains 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."
