2K Games has released a new batch of screenshots from BioShock, illustrating the "spiritual successor" of System Shock 2, due to ship on August 21st 2007. In BioShock, from a first person perspective, we’ll have to explore a bio-lab and fight genetically modified enemies along the way, like drones, predators and soldiers. The AI is said to be very complex, we’ll have the chance to upgrade our alter-ego with genetic implants, use weapons like pistols, shotguns, rifles, which can also be upgraded and used to take advantage of each enemies’ weaknesses, which can only be discovered if they are photographed with a bio-scanner. The engine used is called Vengeance and is an improved version of the one used in Tribes: Vengeance.
