Mission 7 of 90Story mission
Roman introduces Niko to Little Jacob, and the introduction comes with work: a Yardie deal in Schottler has been set up as an ambush, and Jacob wants somebody watching the meeting from a distance with a gun.
It is the first weapon Niko owns — a pistol Jacob hands over in the car — and the first time the game asks him to hold a position and shoot from it.
Sound the horn to bring Jacob out, and he hands over the pistol during the drive.
Leave the taxi at the alley and take the stairway on the right up to the marked spot. Crouching there steadies the aim, which matters with a pistol at this range.
Clear the dealers on the ground below first. The last man comes out through the door on the roof rather than from the group, so the fight is not over when the ground is quiet.
Deliver Jacob to the Homebrew Cafe in Dukes. No pursuit follows.
Who this mission brings together, and the ground it covers.
