If you still have interest after months of delays, 2K's Elizabeth Tobey posted on the official forums to notify us that the DLC for BioShock 2 on PC should be coming at the end of January and beginning of March, though these are not official release dates.
I have an update for you! As of today, we're tracking to submit the Protector Trials to certification at the end of January. Minerva's Den has some more work to be done on it still and is tracking to submit to certification in the beginning of March. I'll let you guys know when we do submit but our release date will change depending on how that process goes (which is why I don't have a firm release date for you guys yet.) I don't have a final patch list for you yet, either, but one item I know many of you will look forward to: we have fixed mouse sensitivity issues and many v-sync option bugs.
