Irrational Games has announced a 1998 Mode for BioShock Infinite: Burial at Sea-Episode 2. The difficulty mode is a throwback to the original Thief, which wants you to complete the story without killing anyone.

Ken Levine, Irrational Games director 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.”

Burial at Sea-Episode 2 will be available on March 25, and will conclude the BioShock time telling stories.
