This Belgian bullpup SMG should be familiar to fans of Ghost in the Shell, Stargate SG-1, and Battlefield 2. Once you unlock it, it just might become your favorite weapon. Sometimes I suspect that fully half the people on any given server I join are using this gun. It combines a high rate of fire, some of the lowest recoil of any SMG, great accuracy, decent damage, and a huge clip to be unmatchably lethal in the hands of almost any player. This gun does everything better than the M4 does except for a very slight increase in recoil and a moderate drop in effective range. Every time I use it it just feels easier to rack up kills than with whatever gun I was using before. That said, I tend to avoid it because it feels like an easy button for the game. So use it for whatever role you play in a match, but be mindful that only using this gun (which you'll be tempted to do) makes you miss out on other fun weapons.
