Drebin Points

Drebin Points
Drebin Points (DP) is the currency earned in Metal Gear Solid 4: Guns of the Patriots used for purchasing weapons and upgrades in the game's pause menu via "Drebin's shop".

History
Drebin 893 makes his living off the War economy and the points that as he puts it "the food on my table". He met Solid Snake and offered him a deal: in exchange for points Drebin would provide Snake with weapons and upgrades for his mission.

When the SOP thorugh GW got hacked by Liquid Ocelot the War economy was stopped as a result it made it almost impossible for Drebin to earn money from the wars. But this did not faze Drebin as he provided his service ,however small it was, to help Snake and Mei Ling's crew stop Liquid. As a result Drebin's products were cheaper but the amount of Drebin Points earned decrease.

After The Patriot's AIs were destroyed and SOP along with them thanks to the FOXALIVE virus the war economy was depleted significantly to the point no one would be able to make a good sum of money. Otacon assumed that this means Drebin is out of work but Drebin ,who welcomed the Patriot's death, has got the Drebins who no longer have to answer to the Patriots can set up their own business.

In 2018 Steven Armstrong's plans to restore the War economy ,though he is killed by Raiden, was sucssesful partly undoing Solid Snake's work in the process. Presumably the Drebins business was booming again.

Mechanics
Drebin points can be earned by collecting weapons, items and emblems and finding secrets. The amount of Drebin Points are earned is dependable on the value of the weapon as an RPG is worth 6000 Drebin Points but a handgun would be worth very little in comparesion.

The emblem with the highest amount of Drebin Points is emblem number 1 "Big Boss" with the lowest being emblem number 40 "Chicken". Listerning to Flashbacks at Shadow Moses Island will earn a large amount of Drebin Points but if the player pauses or moves to the next flashback will not gain the Drebin Points.

On Boss Extreme the player cannot buy non leathal weapons even if they have enough Drebin Points so as to not make it too easy to get the Big Boss emblem.
