That's either the assassin mission that's last then or a Malibu mission, eh? Since you said Phil's were fun
I used shotgun on said badguy and it didn't take long at all. I didn't even need the armor to regenerate, though it was nice that it did.
I never had hidden packages in GTA3, so I guess that's why it was harder for me. I don't have 'em here in GTA:VC either (well, okay, 12 of them I do have), but since they left my weapons, I guess it wasn't too bad. I had like 80 rockets, 1300 uzi rounds, etc. I <b>had</b> some 80 PSG-1 rounds, stupid sniping Auntie Poulet mission.
