The Vampire is the flagship of Zone Control's line. It is, by any definition, a big weapon. It fires 35×40mm shells, and has a semi- automatic/4 round burst/fully-automatic trigger group. It's most unique feature is the feed system. The shells are feed from a pair of detachable box magazines, and can be programmed to fire one magazine (with or without the option of automatically switch over when one mag is empty), or alternating between magazines on a one-one ratio. The typical magazines hold 16 rounds, but four and eight round magazines are also available. In simple words, a grenadier can place 32 grenades into an area in about 5 seconds with very little difficulty.
By using a tactical mix of fragmentation, white phosphorous, smoke and EMP shells, a single individual can easily wipe whole platoons of the map in a matter of seconds. But he better be rich, because feeding these babies really pricey, real fast. The magazines can except no shells over 102mm, but shells up to 130mm may be manually feed into the chamber. A few individuals are known to mount a Viper under the barrel, for carrying special ammunition.
