Jamaican Heat

After the cutscene, you are told to pick up Jacob. After you reach the place, you have to honk and pick him up.

Then you have to take him to Schottler, where he takes you as his bodyguard. He then gives you a pistol to protect him.

After the goons start attacking him, you have to save him.

Interestingly the goons cannot damage him during the shootout, but in a rare glitch when cheats are activated, he can get killed.

The main aim of this mission is to familiarise the player with the pistol mechanics.

After the three guys are taken down, another goon appears on the roof and tries to kill you.

After taking him down, you have to take Jacob back to the cafe.

After the mission is done, if you call Roman after the phone call, you can start doing the Taxi Missions.

Trivia

• Jacob’s gunfire does no damage to his enemies.
