Second Assault

It's time again for yet another Battlefield picture. Being a Battlefield fan (despite the fail with the BF4 launch) my favourite map is actually the most hectic one - Operation Metro, which comes out in this upcoming DLC titled "Second Assault". I love what they did with it in BF4 so I tried to mimic it. Obviously I didn't do a perfect copy of it, but atleast there's some resemblance. Anyway, I hope you guys like it! And let's see if you can find the "hidden" message in this pic.
Took around 13 hours to do with Photoshop CC, about 240 layers.

The image I posted is 2560x1600 so make sure to download the high res version if you want this as a wallpaper.
 
Original size: 3200x2000

Once again, I do this for the community to enjoy but since I do not watermark my images with a huge logo, please link back to my DA page if you want to post this somewhere else. Thanks!
