The third and final sub-area in the Green Zone, is Lincoln Meadows.
Just like the previous sub-zone, known as Fulton, Lincoln Meadows includes two Prototype 2 Lairs, five Prototype 2 Blackboxes and four Prototype 2 Field Ops.
Lincoln Meadows is located on the eastern side of the Green Zone.
After you find all hidden collectables in Lincoln Meadows, assuming that this is the last area you have to explore; you can use the airbridge and travel to the Red Zone.
In this case, the first area you have to explore is Downtown.
If you manage to find all hidden Field Ops in Lincoln Meadows, you will unlock a new predator mutation.
On the other hand, for destroying both Lincoln Meadows Lairs, a new locomotion mutation becomes available.
Additionally, for finding all hidden Black Boxes in this area, you will be able to improve Hellers defense through one of the defensive mutations which become available.
