2K Marin is developingXCOM, notthe2K Marin.
According to1UP, the Australian arm of 2K Marin is the house where the newXCOMtitle is being built, which is not the same house we would attribute as the main driver behindBioShock 2. That one is in Novato, California.
The two are “sister studios,” as explained by a rep speaking with 1UP, and as such, 2K Games simply just rolled with their shared studio name in the press release announcing the revival of the classic IP. But there’s no need to feel burned. These guys apparently did their share of work inBioShock 2and have been around for a bit. We’re excited to see what they’ve got, and even more excited to seeXCOMagain.
