|M4 and Shotgun 'Masterkey'
Magazine: 30 rounds, 5-12 gauge 70mm cartridges
A new addition to DF2, the Master Key combination includes an M4 carbine, with an under-slung Remington M870 shotgun. The characteristics are almost identical to that of the M4/M203, with the exception of the shotgun, which can be used with deadly results in CQB. Still, the M203 grenade launcher should prove more useful than the shotgun on most missions, and is therefore a better choice than the Master Key.
