Where to Find Purgatory in Ninja Gaiden 4

By Ambar Jimenez | 2025-10-22 09:26:25

The Ninja Gaiden series is infamous for its demanding difficulty, and Ninja Gaiden 4 (NG4) delivers on that reputation in spades. While the main campaign is a gauntlet of relentless enemy waves and challenging boss encounters, some of the most rigorous tests of skill are entirely optional—the hidden Purgatory challenge areas.These intense challenge rooms offer massive rewards, including vast amounts of NinjaCoin and Weapon EXP, but finding them is a trial in itself. If you're seeking the "Annihilator" trophy and want to maximize your resources, conquering all 18 Purgatory Gates is a must.Here is everything you need to know about the Purgatory mechanic and the precise location of every hidden gate.

Ninja Gaiden 4: Purgatory Location

Understanding the Purgatory Challenge

Purgatory gates are scattered across nearly every chapter of Ninja Gaiden 4. They are clearly marked by a Torii gate illuminated with a distinctive blue flame.Once you enter a Purgatory challenge, you are immediately plunged into waves of tough enemies, typically variants linked to the chapter you are currently playing. These challenges are reminiscent of the Crystal Skull challenges from Ninja Gaiden 3 but come with a unique twist: the health wager system.

The Risk/Reward Wager

Before beginning the fight, you can choose to wager a percentage of your maximum health to increase the rewards earned upon victory. This allows players to adjust the difficulty and reward based on their confidence:

Realm of Challenge	Health Wagered
Realm of Gods	0% (Standard Reward)
Realm of Man	15% Health Wagered
Realm of War	30% Health Wagered
Realm of Beasts	45% Health Wagered
Realm of Hunger	60% Health Wagered
Realm of Hell	75% Health Wagered

Wagering your health—especially at the higher tiers—creates extreme tension, as mistakes are punished severely. But the massive influx of currency and experience points makes the risk well worth the reward.

Locating All 18 Purgatory Gates

Finding the blue-flamed gates is often the hardest part of the challenge. They are almost always tucked away off the main path, requiring sharp observation and often a bit of tricky platforming.

Yakumo’s Chapters (Chapters 1–13)

Chapter	Chapter Name	Location Guide
Chapter 1	Bloodsoaked Tokyo	After acquiring the Caddis Wire and using it for the first time, you’ll land on a platform. Instead of using the wire again to proceed, head left past the large glowing billboard. Follow this path and climb up to find the gate.
Chapter 2	Haunted District	After the first major rail-grinding section and the introduction of flying grapple drones, grapple up to the next building. Look for blue crates nearby, proceed through them, and you’ll find a hidden rail to grind that leads directly to the Purgatory.
Chapter 3	Phantom Pleasure Quarter	This is one of the easiest. After defeating the first group of enemies, jump up to the next level. Immediately turn around and follow the yellow-marked path opposite the main route to find the gate at the end.
Chapter 4	Pilgrim's Windswept Path	After unlocking the Wing Suit, you'll climb a mountain. Stop at the wall where a wall run and a point zip converge (usually triggering two enemies). Instead of continuing up, head right through a secret, easy-to-miss path.
Chapter 5	Raging Valley	Located shortly after you reach Umi's shop (about halfway through the level). From Umi's shop, jump down and continue forward until you see a staircase next to a door you can't open. Go up the stairs, jump down into the ravine, and follow the path to the right.
Chapter 6	Guiding Winds	After navigating several wind tunnels and reaching a section with many grapple points, continue upwards to a giant rope to grind down. Grind to the wooden platform, then use the wind tunnel but aim sharply to the right (instead of straight ahead) to reach a very sneaky gate.
Chapter 7	Altar of the Mountain God	As you platform across the level, just before reaching the main gate to the boss, head down the stairs, jump across the platforms with yellow tape, and then head left to find the gate.
Chapter 8	Drowned District	Once you acquire the Pond Strider, ride it until you reach the large disco room. Clear the room, then head right of the main path after opening the door, wall-flip up to the next level, and ride your Pond Strider to the gate.
Chapter 9	Realm of the Silent Dead	Early in the level, when you reach the first large pool of water you can use your Pond Strider on, head left instead of proceeding forward. Look for a hole in the wall, jump over, and continue straight.
Chapter 10	Bounding Spirits	This one is near the start. After clearing the first room of enemies, head slightly right of Umi's Shop and through the open door. Follow the path forward.
Chapter 11	Infiltration	Midway through the level, you'll reach a building marked E4 before taking a rail into a room. Stick to the rail until a train approaches, forcing you to jump right. As soon as the train passes, quickly jump back onto the left rail; it will lead to the Purgatory.
Chapter 12	Dragon's Maw	Found late in the chapter. After a major rail-grinding section, clear out the tough enemies in the room. Head toward the exit door, but turn left and grapple across the void using the Caddis Wire point to find the gate.
Chapter 13	Clash of Convictions	At the very start, head backwards and down the stairs. Keep descending until you find a grapple platform on the left that leads to a small platforming section and the gate.
Chapter 14	Unholy Descent	NOTE: Chapter 14 has no Purgatory Gate.

Ryu’s Chapters (Chapters 15–18) & Final Chapter

Chapter	Chapter Name	Location Guide
Chapter 15	Fanged Gate	After escaping the Underworld through a portal and landing in the underground disco, clear the first room. Head down until Ryu sees another portal ahead. DO NOT JUMP IN. Instead, jump to the platform on the left, wall run, and follow the path right through a gate to find the Purgatory on the dance floor.
Chapter 16	Downpour	Found early in the level. After taking the first elevator, continue forward until you reach the open Tokyo street scene. Instantly head right instead of left, wall run, and platform forward to find the gate.
Chapter 17	Howling Ravine	This gate is located in the exact same spot as Chapter 7's Purgatory. Head down the stairs at the beginning and across the platforms to the left.
Chapter 18	Darkness Reborn	After the opening and taking the big elevator, move forward and up the stairs. Clear the next room of enemies, then head left instead of up the next set of stairs. Follow this path to the Purgatory.
Chapter 19	Ebon Wings	The final Purgatory is found in the exact same location as Chapter 18. Follow the same path after the initial section (head left after the main room with the stairs).

By systematically locating and clearing these 18 optional Purgatory challenges—especially utilizing the higher Realm wagers—you will not only earn the highly coveted Annihilator trophy but also stockpile the resources needed to fully upgrade Yakumo and Ryu into unstoppable forces.
