Many Bioshock Infinite fans loved that game’s “1999 Mode” which was the hardest difficulty setting for it. This wasn’t enough for some and they invented self imposed rules such as beating the game non lethally. Irrational Games took note of this and created a new mode for the upcoming DLC Burial at Sea Episode Two.
1998 Mode will make it so that the game can only be beaten by using non lethal tools. This is an additional mode and all of the other difficulties, including 1999 mode will also be available.
The episode is heavily stealth focused so this 1998 Mode is a perfect compliment for it. Look for Bioshock Infinite: Burial at Sea Episode Two to be released on PC, PSN and XBL on March 25th.
