Irrational Games has announced 1998 Mode for BioShock Infinite: Burial at Sea — Episode 2. The difficulty mode calls back to the original Thief — both in concept and in its key art — by finishing the story without killing anyone.
Similar to Infinite’s 1999 Mode, 1998 is a challenging difficulty modifier. Irrational Games director Ken Levine said, “In Burial at Sea – Episode Two we put a focus on balance and stealth mechanics. 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.”
