Vulkanheizer,
Actually the best GTAVC walkthrough is the one found in your heart.
That's right... All you have to do is practice, and be true to the US$39.99 you spent when you bought the game (or the US$3.99 you spent when you rented the game, then copied since you just modded your xbox).
C'mon guys, it's not hard... just play the game for a few hundred hours a week, and you're bound to get all the missions/weapons/hidden packages.
Quit your job if you have to... I DONT CARE!
Do whatever it takes... you think the good people at RockstarGames want you to read a walkthrough?? NO!!!
This forum is about how much this game rules. So stick to it and give of your time, and of your heart.
Yours truly,
B---
