Prologue: Main Missions

As soon as you get control of Michael, you'll see some guards. Don't shoot them directly! Instead, aim your weapon near them (hold [L2/LT] to aim, then [R2/RT] to fire) to scare them into a closet. This is key to not wasting ammo and getting a good start.

Now, head to the safe and steal as much cash as you can. After that, you'll need to shoot the security guard who grabs Michael. Then, press up on the [D-Pad] to use your phone and detonate the bomb. Follow the corridor to the safe, grab the loot, and then meet up with Trevor. You'll get grabbed by security, so quickly press down on the [D-Pad] to switch to Trevor. Aim for the security guard's head by holding [L2/LT] and taking him out.

You're now in a corridor. Hold [X/A] to sprint all the way to the end. When you reach the crates, press [R1/RB] to take cover and wait for the bomb to explode. Once it's safe, open the shutter and take cover behind a pillar. You'll need to take down the police officers who are coming at you. Keep an eye out for the prompt to switch back to Michael.

As Michael, sprint towards the getaway car ahead and take cover. After a few minutes, you'll switch back to Trevor. Sprint towards the vehicle in front of you, taking out any cops along the way. Once the cutscene ends, you'll be driving. Hold [R2/RT] to accelerate and follow the yellow marker on your radar to reach your destination.

Unfortunately, the car won't make it. You'll need to defend Michael by taking out the remaining cops until the next cutscene starts. This wraps up the Prologue!
