Heyy, KILL PHILL II, the mission was so easy, but the end of it is so hard! I get the key card from the fallen gunman, and go to the basememt, and the people in there are shooting like crazy!!!! I just can't walk in there, i'd get killed instantly! Is a rocket launcher fine to use? What weapon should i use and what kind of tactics, ( getting in there, who to kill first? etc... I have tried, like 4 different weapons already.... minugun, flame thrower, laser sniper and a pistol.......

At the end of this mission, when is says to get rid of your wanted level, just put in the "no cops" cheat?
