You've probably seen the opening credits of Grand Theft Auto V more times than you’d care to admit. That snowy North Yankton bank heist is burned into our collective retinas by now. But even years after the initial hype, people are still searching for a solid GTA 5 Xbox One walkthrough because, honestly, Los Santos is huge and remarkably easy to mess up if you’re aiming for that 100% completion stat. It’s not just about finishing the story. It’s about how you play the market, who you kill, and how you handle the weirdness hidden in the Vinewood Hills.
Most people just blitz through the yellow "M" or "F" icons on the map. That's fine if you just want to see the credits roll. However, if you're playing on Xbox One, you're dealing with the version that introduced first-person mode and a ton of extra collectibles that weren't in the original 360 release. If you aren't careful, you'll end up broke by the end of the game with no way to buy the Golf Club or the cinemas.
The Prologue and the Early Hustle
The game starts with a bang, but the real "walkthrough" begins once Franklin and Lamar are repo-ing cars in the sun. Early on, the game feels linear. It isn't. You have choices almost immediately. When you’re playing as Franklin, your focus should be on building his driving skill. Why? Because his special ability—slowing down time while driving—is the single most useful tool for the more annoying timed medals later in the game.
Don't spend money. Just don't.
Every dollar you spend on customizing a car you’re inevitably going to lose or blow up is a dollar that isn't sitting in the stock market. One of the biggest mistakes players make in a GTA 5 Xbox One walkthrough is treating the early missions like a piggy bank. The real money comes much, much later, and it requires you to have a starting "nut" of cash to invest.
Meeting Michael and Trevor
The transition from Franklin’s street-level crime to Michael’s mid-life crisis introduces the heist mechanic. This is where the game branches. During "The Jewel Store Job," you have a choice: Loud or Smart.
Experts almost always recommend the "Smart" approach. It’s cleaner. It requires a bit more setup—stealing the bugstars van and the gas—but the payout is more reliable because your crew is less likely to faff around and lose bags of jewels. Speaking of crews, always pick the cheapest options for the early heists. Yes, they might crash or die, but their stats will grow over time, and they take a much smaller cut than the "experts." If they die, you lose their share anyway, but if they live, you’ve basically "leveled up" a cheap employee into a pro.

The Lester Assassination Strategy
This is the part where most walkthroughs fail to give you the specific timing. Lester Crest will eventually offer Franklin assassination missions. Stop. Do not do these.
Well, you have to do the first one (The Hotel Assassination) to progress the story. But after that? Leave the rest until the very end of the game. If you wait until after the "Big Score" heist—where you walk away with tens of millions—you can dump all that cash into the stocks Lester mentions. We're talking about turning $20 million into $200 million per character.
- The Hotel Assassination: Invest in Betta Pharmaceuticals (BAWSAQ).
- The Multi Target Assassination: Invest in Debonaire (LCN).
- The Vice Assassination: Invest in Fruit (BAWSAQ).
- The Bus Assassination: Invest in Vapid (BAWSAQ) after the mission when the stock bottoms out.
It's tedious to wait, sure. But being a billionaire in Los Santos makes the endgame content, like buying the $150,000,000 Los Santos Legend property, actually possible.
Navigating the Xbox One Specific Content
The Xbox One version isn't just a port; it added the "Wildlife Photography Challenge" and the "Monkey Mosaics." If you're looking for a true completionist GTA 5 Xbox One walkthrough, you need to be looking for these.
The Monkey Mosaics are 50 small pieces of street art scattered across the map. Finding them all unlocks some unique outfits for Trevor and a special "Go Go Monkey Blista" car. It sounds like a chore—and it kind of is—but it's part of that 100% checklist that separates the casuals from the pros.
Then there’s the First-Person mode. It’s a literal game-changer for shooting. If you’re struggling with the sniping missions or the "Rampages" with Trevor, flip into first-person. The aiming feels much more like a traditional shooter and less like the "floaty" third-person lock-on system Rockstar usually uses.

Don't ignore the question marks on the map. Some of the best writing in the game is tucked away in these side stories. The Epsilon Program (the cult Michael can join) is a massive time sink—you literally have to run five miles in the desert at one point—but it pays out $2.1 million if you choose to betray them at the end.
Then there’s the "Last One" mission, which only unlocks after 100% completion. It involves hunting a Sasquatch. Yes, really. It’s a nod to years of GTA myths, and it’s one of those "you had to be there" moments for the community.
Managing the Three-Character Dynamic
The "Character Switch" is your best friend during a GTA 5 Xbox One walkthrough when you're stuck in a police chase. If you aren't currently on a mission, switching characters can sometimes clear your wanted level or at least move you to a safer spot on the map.
Trevor is your tank. Use him for the heavy lifting. His special ability makes him nearly invincible and allows him to deal double damage. Michael is the marksman; his bullet-time is essential for headshots during the big shootouts. Franklin, as mentioned, is the wheelman.
A pro tip for the "Three's Company" mission (the one where you abduct the guy from the FIB building): stick with Michael on the rope for as long as possible to get the hang of the rappelling, but switch to Franklin for the sniping portion to keep the heat off the helicopter.
Common Pitfalls and Technical Glitches
Xbox One players occasionally report issues with "The Big Score" where the game might freeze during the switch between characters. To avoid this, try not to use the "Skip Journey" feature if you’ve failed a segment of the mission. Let the game play out.

Also, make sure your auto-save is on, but keep at least three manual save slots. One for before heists, one for after heists, and one "general" slot. Rockstar games are massive, and while they are generally polished, a script failing to trigger can ruin 40 hours of progress if you don't have a backup save.
Achieving the 100% Completion Stat
To "finish" the game in the eyes of the Xbox Achievements, you don't actually have to do everything. You need:
- All 69 Story Missions.
- 42 Hobbies and Pastimes (including winning at darts, private dances, and street races).
- 20 Strangers and Freaks missions (specifically the ones for Franklin).
- 14 Random Encounters.
- 16 Miscellaneous activities (like buying a car online or going to the movies).
The "Random Encounters" are the ones that catch people off guard. You might be driving to a mission and see a woman being kidnapped or a guy whose bike was stolen. Stop and help. These count toward your percentage and often lead to better rewards later, like a new heist crew member with high stats and a low cut.
Practical Steps for Your Playthrough
If you’re starting a fresh run on your Xbox today, follow this order of operations to maximize your time and fun.
- Focus on the story until you unlock all three characters. The game doesn't truly "open up" until Trevor moves to Los Santos.
- Invest in the "Sonar Collections Dock" as soon as it's available. It costs $250,000, but it gives you access to the submarine. Collecting nuclear waste is a slow but steady way to make back your investment if you're bored.
- Collect the Spaceship Parts and Letter Scraps early. Use an interactive map on your phone while you play. Doing this incrementally is much less painful than trying to find all 100 items in one go at the end.
- Ignore the expensive car upgrades until you've finished the Lester Assassinations. You'll want that money for the stock market.
- Complete the Flight School with Michael. It’s annoying, but it maxes his flying stat quickly, which makes the late-game heist escapes significantly smoother.
The beauty of the GTA 5 Xbox One walkthrough is that it's your story. You can be a professional criminal, a chaotic madman, or a guy who just spends four hours playing golf. Just remember to save often and keep an eye on the BAWSAQ.
Once you've wrapped up the main story and the assassinations, the world is yours. You can buy the tank, find the UFOs, or just cruise the Pacific Coast Highway listening to Non-Stop-Pop FM. The game is over a decade old, but the level of detail in Los Santos still puts most modern open worlds to shame. Keep your eyes open for the small details, like the way the NPC dialogue changes based on which character you're playing, and you'll see why people are still playing this version today.
