The collection of hidden packages in the series is considered a side quest of sorts wherein the player is given the opportunity to amass rewards by collecting as many of these pickups, typically placed in conceiled locations or hard-to-reach places, as possible.
GTA III features 100 white bundles with possibly SPANK in them, around Liberty City which the players collect. In GTA Vice City, the hidden packages are again a number of 100 and appear in green "tiki statues" all over Vice City. In GTA Advance, the packages are again in form of white bundles and a number of 100 just like it's predecessors. GTA: Liberty City Stories lets the hidden packages return for the fourth time showing 100 white hands with the sign of the horns gesture. For each hidden package collected, the player receives money. Hidden packages are also required for 100% completion.
It is wise to collect all availble hidden packages at the begining of the game, as it gives you weapons that could be useful for some of the harder missions, plus you wont have to spend money after getting busted or wasted.
Rewards
Special rewards are offered for finding each tenth hidden package.
In GTA Vice City, inside of the Ocean View Hotel upon finding 100 hidden packages, there is a Tiki statue broken in half with a white powder (supposedly cocaine) spilling out of it.
