I believe that this game is a good attempt at a shooter that tries to have some kind of alternate history. When I first started playing the campaign, the visuals were awful, the sound was pretty bad, but the story was at least decent enough that it made me want to play through it. Thankfully it was short and got a chance to play the multiplayer, which I'm still getting used to, but having a lot of fun playing it. I think the game is okay, not the best out there, but worth checking out once it's discounted. 
 
Give it a shot.
