Grand Theft Auto IV/Friends

There are up to five possible friends to do activities with throughout the game. Once you get a friend's "like percentage" high enough, then it will unlock there special abilities (The respect stat has no influence on unlocking special abilities). Unlike girlfriends, you can only take a friend to activities that they like (These are predetermined and are the same for every game). You can do up to three activities at once. If you accidentally kill your friend or they are killed by a police officer because they are drunk, you will get a call from them asking you to pick them up and then return them home. If you kill your friends intentionally, well you can expect them to like you a little less. Doing activities with Little Jacob, Brucie, and Packie count toward 100% completion (Roman and Dwayne don't).

Wake Time
Little Jacob is awake from 1pm-4am. Don't call him before he is awake because he will lose respect and like for Niko.

Ability
Guns: Once Little Jacob like stat is up to 75%, you can call him and he will setup a meeting with you where he will sell Niko weapons at a significantly cheaper price than the LCGC. However, don't be an hour or more late otherwise he will leave and Niko won't be able to use the ability for another day. Also, don't go to the meeting with any wanted stars because Little Jacob will leave as soon as you get there because, as in real life, gun running is illegal and he doesn't want to be caught. Drop off of his ability occurs if he likes Niko 40% or less. Don't attempt or even think about stealing his gun car.

Other Details
He prefers fast food and loves Cluckin Bell. His nightspot preference is Club Liberty in Northwood, Algonquin. Doing Little Jacob's drug delivery also boasts his like stat (if you successfully do them).

Wake Time
Brucie is awake from 7am-1am. Don't call him before he is awake because he will lose respect and like for Niko.

Ability
Chopper: Call Brucie once his like stat is up to 75% and he will fly to the closest location to you and get in his helicopter. He will take you to a predetermined location that you choose (i.e. You can't tell him to land anywhere you want him to). You aren't able to jack the helicopter from Brucie. Drop off is at 40% or less.

Other Details
Avoid fast food restaurants and try as high end as possible. Any high-end nightspot is fine by him. Brucie has two activities that no other friend has in boating and helicopter ride. They are generally the same idea in that you drive the boat (or helicopter) to the location that Brucie says (it's the yellow dot) watch the cut-scene and head back. Don't crash the helicopter because you (1) die and (2) lose respect and like from Brucie. There is no possible way to steal the helicopter.

Ability
Backup: Once Dwayne like stat is above 75% call him and he will send two (armed) gangsters that will follow Niko until they (or Niko) are dead (Now that's loyalty). Killing the gangsters yourself doesn't seem to make Dwayne lose respect. Drop off is at 30%.
