In an interview with Kent Hudson from 2k Marin, it was revealed that BioShock 2 DLC is in the works.
“Absolutely! We are working on pretty aggressive plans for DLC and that’s actually something that is already under-way. That is something that is mostly being run out of the Marin studio because like I said the Australian studio is already ramping up on the next big thing.” (via AustralianGamer.com)
Honestly, I don’t think this is any big surprise to anyone, but it’s nice to see there’s some coming. I’ll bring in more information about it as it comes.
