He rolls around on rollerblades. He stops to drink wine through a straw. He’s obsessed with "party favors," which is just a fancy way of saying C4 explosives. Honestly, Metal Gear Solid 2 Fatman shouldn't work as a character. On paper, a bomb disposal expert in a massive, EOD (Explosive Ordnance Disposal) suit who glides across a helipad sounds like a discarded fever dream from Hideo Kojima’s sketchpad. Yet, decades after the game hit the PlayStation 2, he remains one of the most mechanically unique and thematic boss encounters in the entire franchise.
It's weird.
Most bosses in the Metal Gear series want to kill you with a gun or a sword. Fatman? He’s playing a different game entirely. He’s testing your patience and your ability to manage stress under a ticking clock. If you aren't paying attention to the sensor, you're dead. It’s that simple.
The Philosophy of the Blast Zone
The fight takes place on the Strut L helipad of the Big Shell. By this point in the game, you've already met the guy once in a cutscene, but nothing quite prepares you for the actual mechanics of the duel. Unlike the high-intensity shootout with Revolver Ocelot or the sniper duel with Fortune, the encounter with Metal Gear Solid 2 Fatman is a frantic game of hide-and-seek.
Fatman represents the "Dead Cell" philosophy of chaos. He was mentored by Peter Stillman, the legendary bomb disposal expert, but Fatman didn't want to save lives. He wanted to be the greatest. In his mind, the only way to prove you’re the best at defusing bombs is to be the best at planting them. It’s a twisted, ego-driven logic that makes him more of a tragic figure than a traditional villain. He’s a craftsman. An artist of the explosion.
He moves fast. His suit makes him nearly impervious to standard gunfire while he’s standing up. To actually hurt him, you have to knock him down, which usually involves shooting him in his skates or his head until he loses his balance. Once he’s on his back, flailing like a turtle, you can finally deal real damage.
Why the Mechanics Frustrated Everyone
Let’s be real: people hated this fight back in 2001.

The main reason is the C4. Fatman doesn't just shoot at Raiden; he spends the entire fight planting bombs around the crates on the helipad. If you don't find them and freeze them with your Coolant spray, the countdown hits zero and it’s game over. It forces you to constantly switch between your weapon and your sensor. It’s a rhythmic disruption. You want to focus on the boss, but the game forces you to focus on the environment.
This is actually a brilliant piece of game design. It mirrors the real-life stress of EOD work. You can’t focus on the "enemy" because the "object" is the real threat.
- The Sensor A is your best friend. Without it, you’re just running blindly.
- The skates are the weakness. If you can’t hit his head, trip him.
- The wine break. Every so often, he stops. He literally takes a break to admire his handiwork. This is your biggest window to punish him.
Wait, did I mention the birds? If you kill the seagulls on the helipad, it actually affects the "luck" mechanics in subtle ways across the game, but during the Fatman fight, they’re mostly just a distraction. Kojima loves those little details.
The Legend of Peter Stillman and Fatman's Origin
To understand why Fatman is so messed up, you have to look at Peter Stillman. Stillman is the one who "lost" his leg in a church bombing years prior—a bombing that, as we later find out, was a hoax he created because he couldn't actually defuse the bomb. Fatman was his apprentice. He knew the truth.
The resentment Fatman feels toward his mentor is palpable. He mocks Stillman’s "Greatest Hero" persona. When you finally take Fatman down, his dying words aren't about some grand political conspiracy like the Patriots or the S3 Plan. They are about his own legacy. He wants to be remembered. "I am the greatest! No one can stop the countdown!"
It’s almost a meta-commentary on the game industry. Fatman is the "creator" who is so obsessed with his own fame that he’s willing to burn everything down just to ensure his name is on the plaque.

How to Beat Metal Gear Solid 2 Fatman Like an Expert
If you're playing the Master Collection or an old copy on a PS3, there are a few ways to make this fight trivial. Most players try to chase him. That’s a mistake. Fatman is faster than Raiden on the skates.
Instead, you should plant Claymores.
Yes, you can use explosives against the bomb man. If you place Claymores in the narrow lanes between the crates, he’ll roll right over them. It knocks him down instantly. No need for precise aim with the SOCOM or the M9. Just set the trap and wait for the "Whoosh" of his skates to get closer.
Another pro tip? Use the Punch-Punch-Kick combo. If you get close enough, Raiden’s physical attacks are surprisingly effective at knocking him off balance. Just don't get caught in his point-blank gunfire. He carries a Glock for a reason.
Once you "deplete" his health, he doesn't just die. He gives you one last puzzle. He hides a bomb under his own massive body. You have to drag his corpse away to find the final "party favor." It’s a final middle finger from a character who refused to let the spotlight go.
The Thematic Weight of the Suit
The "Fat Man" suit isn't just a gimmick. It’s a reference to the atomic bomb dropped on Nagasaki. The Metal Gear series is obsessed with nuclear history, and naming a villain after a weapon of mass destruction isn't an accident. Fatman is the personification of the "uncontrollable blast."

He is bloated, heavy, and destructive. But he’s also surprisingly agile. This juxtaposition is what makes the Big Shell feel so dangerous. You aren't fighting soldiers; you’re fighting personified concepts of warfare. Fatman is the "indiscriminate" nature of explosives. He doesn't care who gets caught in the radius.
What Most People Get Wrong
People often think Fatman is just a filler boss. They see him as a break between the "important" plot points involving Vamp or Solidus Snake. But Fatman is the one who actually teaches the player how to navigate the Big Shell under pressure.
He’s the gatekeeper.
If you can't handle Fatman, you aren't going to survive the final stretch of the game. He forces you to master the first-person aiming, the item switching, and the environmental awareness that the game has been trying to teach you since the Tanker chapter.
Actionable Insights for Your Next Playthrough
If you're heading back into the Big Shell, keep these specific strategies in mind to handle the Fatman encounter without the usual headache:
- Priority One is the Sensor: Never engage Fatman if there is a yellow dot on your radar. The C4 is the only thing that can actually end the game instantly. The bullets just hurt.
- Use the M9 for a Non-Lethal Run: If you're going for a Big Boss rank, you need to use the tranquilizer. It takes longer to knock him down, but it’s the only way to keep your kill count at zero.
- The "Corner Trap": Fatman has a predictable pathing algorithm. He tends to circle the outer edge of the helipad before weaving through the middle. Stand near the center and let him come to you.
- Don't Forget the Coolant: Make sure your Coolant spray is fully equipped before the cutscene ends. Fumbling in the menu while a 30-second timer is ticking is the leading cause of "Game Over" screens in this section.
- The Final Bomb: After the fight, immediately hold the action button to drag his body. You only have a few seconds to find the hidden C4 under him. Don't stand there celebrating.
Fatman is a reminder of when boss fights were weird, experimental, and genuinely challenging in ways that didn't just involve "dodge-rolling" at the right time. He’s a relic of a golden era of tactical espionage action.
