Check out my Prototype 2 (HD) Walkthrough !
Let's go out to the city and have ourselves a snack. Our Prototype 2 Walkthrough includes videos for finding collectibles, crushing enemies, and obtaining secrets.
Green Zone Collectibles
The Green Zone has many more collectibles compared to the previous Yellow Zone. This means more leg work, but in turn more upgrades to Offensive, Defensive, Predator, Locomotion, and the new Power Specialist.
Salt Yard Plains
The Salt Yard Plains contains only four blackboxes, making it your prime target for a quick offensive boost.
The Lairs of Lincoln have many tough infected, and will introduce a deadly hybrid in the form of evolved humans.
Most of the strong infected can be consumed for huge bastions of free DNA.
