You need to attack into forellis warehouse and kill forellis muscle when you have killed him he's gonna tell you where is another warehouse and where is forellis right hand guy. Forellis know that you gonna hit to the other warehouse so its heavily guarded and you have an idea thats you need hunter you stole one and you need to shoot down hunter too but its dont matter because you have hunter too ;) around ware house gonna be some rocket launcher guys so be careful.
