Yesterday's announcement of XCOM might have told us that the game is "currently in development at 2K Marin, the studio behind the multi-million unit selling BioShock 2", but it's not actually being worked on by the core BioShock 2 team. In fact, XCOM isn't even being developed in Marin.1UP
reports that the game is actually being handled at 2K's Australian studio. This does not, however, make the above quotation from the
XCOM press release completely false, however. Oh no! You see, 2K Marin and the studio formerly known as 2K Australia are now "sister studios" operating under the 2K Marin moniker.
The Australian studio (now officially "the Canberra, Australia arm of 2K Marin") did have a bit to do with
BioShock 2, but the core team was tucked away in Marin.
See what they did there? The announcement is still technically true, while being... well, we'll say 'misleading'.
