Former US Navy SEAL, 'Mack' is back for another Ghost Recon: Future Soldier 'Believe in Ghosts' video, and this time he's looking at the game's Gunsmith weapon customisation system. Specifically, Mack is looking at breaking into a compound like the US did when they tracked Bin Laden to a facility in Pakistan.

Using the Adaptive Combat Rifle, a thermal camera and an X-ray scope to see enemies through walls. Or there's the thrown sensor, which updates your HUD with the positions of enemies leaving them primed for a fast breach and clear. They'll never see you coming.

Check out part two of the three part 'Believe in Ghosts' series below, spend just over three minutes with Mack talking you through weapon customisation, then look forward to Tom Clancy's Ghost Recon: Future Soldier on May 22nd in North America and May 25th in Europe.
