Grand Theft Auto V

This trophy will be awarded once you complete the Finale of Act III.

The Act contains 6 Prep Missions, 5 Setup Missions, and 1 Finale. Act III will be available to start as a Heist Leader once you have completed Act II. Alternatively, you can play through the Act as a Heist Crew Member with a friend or with others through public matchmaking: you just need to complete the Finale to unlock the trophy.

Below are some tips for completing the Act.

Setup 1: Rescue Agent 14
In this Setup, you’ll head to South Los Santos and deal with a bunch of enemies to rescue Agent 14.

An Armoured Kuruma will be useful for the combat and for dealing with the Juggernauts which appear after you clear the first round of enemies. Try to position your Kuruma such that it's distant from the Juggernauts and exposed to only 1 at a time, and have your team pepper the Juggernauts' heads with AP Pistols. Should your Kuruma take a significant amount of damage in this Setup, you can drive away, blow it up and then retrieve it via your mechanic after calling Mors Mutual Insurance to reclaim it.

Alternatively, pepper the Juggernauts with a minigun or RPG: the minigun can take the Juggernauts out in a matter of seconds. If visibility is an issue, i.e. the Juggernauts are around a corner and you cannot shoot at them, switch to the RPG and fire rockets into their vicinity to inflict damage. A Combat MG will also work well if you prefer.

Setup 2: Escort ULP
This is quite a simple Setup that involves taking control of and using a mobile ballistic missile launcher. You will have to defend a ULP Agent with it who is being transported in a helicopter to the Sandy Shores area.

Those who aren’t in the missile launcher will benefit from being in an Armoured Kuruma as the Agent will take a while to get to his destination, and enemies will be coming after you with ground and air vehicles.

The person controlling the missile launcher should focus their attention on the enemy helicopters, since they can damage the ULP Agent's helicopter. Luckily, the Agent ULP's helicopter can take quite a bit of damage.

Make sure you stock up on snacks and armour before attempting this Setup as it takes around 20 minutes to complete.

Setup 3: Barrage
Head to the Los Santos Observatory and intercept an arms dealer flying by with a fleet of helicopters.

You will need to destroy a Carbogob which is transporting a Barrage - a weaponised SUV which you require. Make use of the Explosive Sniper Rifle rounds you are given to take down the fleet of helicopters which pass by. To make the mission easier, you can damage the Cargobob until it is almost destroyed (its health bar can be tracked on-screen), and follow it until you are approaching the Sandy Shores area. Finish the Cargobob off here and collect the Barrage, this way you will not have to transport the Barrage as far and so will encounter fewer enemies on the route back.

Setup 4: Khanjali
Head to the abandoned airfield to retrieve a Khanjali - a new tank introduced in this DLC.

There will be a few enemies to take out and several weapons crates to destroy. Use the Armoured Kuruma to make this mission a breeze. Overall, a fairly simple Setup.

Setup 5: Air Defences
Use the Volatol jet to fly-by and destroy enemy SAM turrets using its bombs.

There is not too much to this Setup, just try to avoid crashing the jet and you should be onto the Finale in no time.

Finale: The Doomsday Scenario
This is it, the last Finale. Stock up on weapons, armour, and snacks before starting the Finale as it is will take some time and involve a good deal of combat.

Once you start, you are tasked with heading to the previously acquired Khanjali or Barrage. I advise taking the Khanjali Tank for the added protection against enemies and its major firepower. After taking your preferred vehicle, make your way to the tunnels in Mount Chilliad and drive through them, you will eventually have to get out of the tank and proceed on-foot.

You will face several Juggernauts, so use the techniques you practised in Setup 1 to take them down - you can take down the first set you encounter using the Khanjali Tank, which will take them out with ease. Continue making your way through the tunnels, and after an amusing cutscene, you will enter a lab containing several servers which need to be hacked. The hacker should complete the hacking minigames as quick as possible while their teammates provide cover. After a lengthy combat & hacking section in the server area, pursue your target and finish off the Doomsday Heist.

If you are struggling with any of the free mode Prep Missions, try joining a new session. The new session may have fewer players and allow you to deliver vehicles without other players interfering. Note you are permitted to skip Prep Missions by paying for them, you will still unlock the trophy, though this will reset any progress you have for Criminal Mastermind (see Masterminds for more).

You might find some of the combat in Act III testing, so make the most of the advice given in the Tips & Strategies Section to make life easier.
