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 Main Story
The Green zone has more dangers than the previous Yellow Zone. Blackwatch is crawling around everywhere and many infected are rampant in the streets.
This is your passage from the Yellow Zone to the Green Zone.
Stranger Among Us
You'll be shapeshifting into one of the enemy Blackwatch. Do not switch back to Heller or use your power, otherwise your cover may be blown.
A Nest of Vipers
Head into the lair and get equipped with the awesome might of Hammerfisting.
Completing this mission will unlock the Blade power and Tornado charge attack.
