2K Marin has published a Q&A detailing the all-new PS3 specific game mode, Survivor, a mode even BioShock veterans will find "highly challenging".

"You're more vulnerable, enemies are tougher, every resource is more precious," explains the Q&A. "You won't be blazing through spaces. You won't be flush with resources. Every fight is a decisive, life-or-death struggle."

Regarding the enemies players will face, the Q&A states: "The enemy population numbers haven't changed, but every single enemy is tougher and deals more damage to you. Additionally, if you die and resurrect at a Vita-Chamber, you get less EVE back, so death has a real sting to it."

Head over to the Cult of Rapture website where you'll find the Q&A in full and a podcast with some of the guys from 2K Marin.
