"Bioshock" fans have another reason to replay "BioShock Infinite: Burial At Sea Episode 2" when they finish it with a normal playthrough because Irrational Games said the new "1998" game mode will challenge gamers to play it again but with a twist.

Many "BioShock Infinite" fans are familiar with "1999" Mode which was introduced as the hardest difficulty mode in "BioShock Infinite".

Now, in conjunction with the upcoming DLC, "BioShock Infinite: Burial at Sea Episode Two" which is being released on March 25, the brand new "Thief" inspired "1998 Mode" is going to be included!

The new "1998" mode challenges gamers to complete the story using only non-lethal tools. This mode will be in addition to existing difficulty modes, and the aforementioned "1999" Mode.

"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."

"We look forward to seeing our fans attempt to conquer 1998 Mode in BioShock Infinite: Burial at Sea - Episode Two, utilizing the new stealth-oriented gameplay as you take on the role of Elizabeth, and see the world through her eyes. Don't forget about the Season Pass, allowing you to get the DLC packs at a significant discount." Said Irrational Games about the new game mode.
