Irrational Games shipped BioShock Infinite out last year with 1999 mode, the hardest difficulty level that the game had to offer. Now, it wants to one up itself and really make you struggle to get to the end of Columbia.

Along with the BioShock Infinite‘s “Burial at Sea” – Episode 2, Irrational will be including a 1998 mode in the new package. This new mode will heavily focus on stealth and only allow Booker to use non-lethal tools in combat.

“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 [sic]. 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.”

In our review last year, I had mentioned I felt like I was leaning too much on the game’s firearms and not enough on other means of combat like the Skyhook or Vigors. Non-lethal playthroughs have never been my thing though, so I’m not sure if this will be up my alley. I can really dig the shape of the hypothetical box Irrational is using to advertise with. My shelves used to be littered with awkward boxes like that back in 1998.

Are you up for the challenge? BioShock Infinite‘s “Burial at Sea” – Episode 2 will put you in the shoes of Elizabeth and be released on March 25th.
