is it possible to play as Mercer? (Prototype 2)

1) Go through the entire campaign mode and testing;
2) Open the map up at the top section of RADNET, click on it;
3) next, section awards -> skins player. Choose Mercer, play.
Not to replay the whole game, you can download sohranki from the Playground and throw yourself. And so I did.

I better pass)

Thank you.
