Yellow Zone Main Story
Feeding Time and Salvation
Feeding Time will unlock your infected shielding, allowing blocking, counter attacks, and projectile reflection. Salvation is a protection mission...of a building. If you get in too much trouble, remember that damage will be restored if you reload a checkpoint.
Lab Rat and Mad Scientist
During these missions you'll have to make use of your shields to not only block, but also counter attack the heavy brutes.
Orion Phase Two and Natural Selection
This is the final section of Yellow zone and a showdown with the boss of the area.
