a very good combination of hero's & stories
1st of all you can do almost what ever you want...like hijacking armor,doing stealth works,finding the story by consuming people and a lot more...
2nd is that Alex(the main character) is a combination of following hero's and the abilities match with each other and make's you a big army of one man(or thing):
-it has the background of resident evil because of the virus and the zombies!
-Alex jump's and smashes the ground like hulk!
-Alex can fly like superman!
-Alex run's on the wall's like prince of Persia!
-Alex can hijack tanks,helicopters like gta!
-the slow motion parts is like Max Payne!
-Alex's cloth is much like assassin creed!
...
so the game would be amazing!
but there is just 2 problems:
-graphics
-and Alex can't swim!!!
but I think the speed of the game and the hole game play will cover the graphics.
and at the end excuse my English!!! if there were any mistakes in showing my opinion...
