Well the plot is quite simple and quite common in games,a revenge story,where James Heller a former US Marine Sergeant and the second Blacklight being accuses Alex Mercer and his “Mercer virus” responsible for the brutal murder of his wife and daughter. Also he accuses himself somwehat of leaving them alone in an infection ridden city and not being able to make it in time to save them. The moment he hears about Mercer being spotted in a red zone he went for a suicidal encounter with Mercer all alone and ends up being infected by mercer like all the others. But surprisingly his DNA adapted the virus same way Mercer’s did and then begins his vengeance ridden rampage against Blackwatch and ultimately Alex Mercer and his virus.
The Plot is one of the highlights as its really a topsy turvy tale with lots of twists and turns.I wont reveal much just to keep the review spoiler free but the plot and overall story is very well knit with almost perfection or close enough to it. Though the missions at a point becomes stale as u got to do the same thing – Locate ,Hunt ,Consume but the good part is the number of ways u can do it like using stealth or wildly rushing in ,killing all and consume (the way i love :D)
