This guide covers every spot for collectibles in Ninja Gaiden 4, helping you snag all the related trophies and achievements (Gourdies, Purgatory Trials, Health Upgrades, Missions, Accessories).
Good news: nothing's missable. You can jump back to chapters anytime in New Game+, and replay them to grab what you missed. Stick to the easiest difficulty for these, as the harder difficulty include they pack tough mini-bosses and enemy swarms. Progress saves to your profile at checkpoints.
Quick rundown on collectibles and their trophies/achievements:
- 15 Gourdies – trophy Critter Collector – These are tiny beige critters with pointy teeth that look like gourds. Two kinds: normal and blue. Normal ones hang out still, and you catch them by nailing a button combo. Blues are jumpy—sneak up from behind when they're not looking.
- 18 Purgatory Gates – trophy Annihilator & trophy Challenger of Challenges – There's one per chapter (except Chapter 14), and they're usually easy to spot. Often, just poking into a side area does the trick. Pick your difficulty when you activate one, and you unlock trophy Annihilator by clearing them all. For trophy Challenger of Challenges, tackle them all on the hardest setting. Save that for later—replay from the menu after you've geared up with all weapon upgrades and items.
- 10 Health Upgrades (20 Upgrade Items) – trophy Ninja Fortitude – These show up as Dragon Lord’s Grace, made from 1x Black Scale and 1x Phantasmal Herb. Grab one of each, and the game mixes them automatically to boost your health bar. You can't snag the finished item straight up; hunt them separately so the game crafts it. That means tracking down 20 items total for all 10 upgrades. This guide hits the ones in chests—the rest drop as mission rewards.
- Missions – Ninja Business trophy & Work Horse trophy – This guide flags all the chapter-specific missions, tucked in side spots that are easy to skip if you're glued to the main path. General missions pop up anytime in any chapter. Always grab every mission at DarkNest terminals, and turn them in ASAP at the next one—some chain off others.
- Accessories – The accessories in the game are not required for any trophy, however they will grant useful abilities and as such are worth collecting. Most of them are automatic rewards for completing missions or combat trials, this guide specifically points out the ones you collect from chests, and the rest will come as automatic rewards.
Chapter 1: Bloodsoaked Tokyo
Mission #1 – Execute the D.D.O. distribution officers (Target Area: Sky City Tokyo)
Once you hit the zone with that huge mechanical doll head floating overhead, hang a right instead of left on the story route. Head right then left (no choice there anyway), and wall-run over two wide gaps. You'll wind up in a blind alley with a giant fan blade looming behind. The officer's hanging out— just wipe out all the foes.
Purgatory Gate #1
Right before your second Caddis Wire swing over a building gap, veer left to spot three parked dump trucks. Dash past them, hook a left into an alley, and pull off the flying bird technique. Up on the roof, the gate's dead ahead.
Gourdy #1
From that last spot, drop back to the main route and zip across the gap with the Caddis Wire. On the far side, swing left not right, and you'll see the Gourdy chilling by some crates.
Accessory #1 (Cobalt Ring)
After another Caddis Wire leap, you'll run into your first surveillance drone (the hookable kind) with flat screens behind it. Usually you'd gate left, but go right this time. Trail the path to a dead-end alley and crack the chest for the Cobalt Ring.
Mission #2 – Find the data chip in Sky City Tokyo (Target Area: Sky City Tokyo)
When you reach the troop carrier aircraft on the heli pad, check the far right corner straight ahead—three chests lined up. The data chip's glowing blue on the floor left of them. You'll basically trip over it on the main path, so it's tough to overlook.
Chapter 2: Haunted District
Purgatory Gate #2
As you step into the stage with flying D.D.O. enemies and drones, hook the Caddis Wire up the big building ahead, swing right, and weave through the blue shipping containers to hit a separate monorail track in a wrecked building. It's the non-glowing one. Grind it till you bail, then climb stairs to the gate.
Health Upgrade #1 (Black Scale)
Post the big scrap with flying D.D.O.s and drones, you'll hit a new monorail track you could grind, but turn left and pop the chest in front instead.
Mission #3 – Execute the D.D.O. bodyguards (Target Area: Sky City Tokyo)
After the second main monorail stretch, you land in a spot with two regular shops and a flying bird jump zone. After the jump, spin around instead of forward. Leap the gap left and hop another monorail. At its end, fight the airborne and ground enemies. Clear 'em to wrap the mission.
Gourdy #2
Push the story till you reach a square room with a busted yellow monorail track left and vendors right. Scale the shipping containers to nab the game's second Gourdy.
Chapter 3: Phantom Pleasure Quarter
Purgatory Gate #3
After the flying bird flip up the shaft near the start, turn back and tail the alley instead of bridging ahead for the main path. The gate's in yet another dead end.
Mission #4 – Find the rotting charm in Sky City Tokyo (Target Area: Sky City Tokyo)
Once inside the temple and the main door to the second Daemon boss phase slams shut, detour left. Wall-run the gap, scrap the first small demon pack, climb short stairs, and duck behind the right shipping container for a chest hiding the charm.
Mission #5 – Execute the food thief (Target Area: Sky City Tokyo)
From the last mission, drop down under the upper floor you just cleared. Crack the left gate open, and the thief's at the corridor's blind end. Izuna drop him for a fast takedown.
Health Upgrade #2 (Phantasmal Herb)
After your first Burabura lantern daemon run-in, hang right and climb the skinny stairs. Chest with a Phantasmal Herb waits at the top.
Gourdy #3
In the wall-run spot to hit a higher platform for the main path, drop down and push straight into a trash-strewn room with the Gourdy.
Mission #6 – Execute the renegade D.D.O. soldiers (Target Area: Sky City Tokyo)
Again, in that wall-run-to-higher-platform section for the story, drop down and veer right into a corridor. At its end, off the renegade D.D.O. soldiers.
Chapter 4: Pilgrim’s Windswept Path
Health Upgrade #2 (Black Scale)
After smashing the wooden barricade into a stealth zone with three officer enemies, finish the stealth bit and go left not right on the story. Wall-run up, and grab the Black Scale chest right before a huge tengu statue.
Mission #7 – Execute the tengu leaders (Target Area: Fuuhaku Sanctum)
Just after unlocking the Dragonfly Glider, skip the busted bridge ahead and detour right through a canyon. Mix wall-runs, Caddis Wire, and a fallen tree bridge. It dumps you at a big shrine gate where the tengu leaders spawn. Drop 'em to finish.
Gourdy #4
Right out of a short cave before your second Dragonfly Glider use, turn right not glider. The blue Gourdy's on a lower ledge. Blues spook easy, so stealth it. Caddis Wire to the pillar behind it—leap off the cliff and mash the button quick, or it'll spot your fall. Pull up, then drop behind and snag it.
Mission #8 – Find the secret supplies in Fuuhaku Sanctum (Target Area: Fuuhaku Sanctum)
Post-second Dragonfly Glider, you hit a crashed freight train rubble pile. Two orange chests and a blue one there count as the secret supplies.
Purgatory Gate #4
While Caddis Wiring through the canyon, you hit a skinny cliff meant for a flying bird flip up a rock wall. Instead, turn back from the path. Trail the narrow ledge to this chapter's gate.
Chapter 5: Raging Valley
Gourdy #5
In the cave network, hit a fork with three green torches overhead and a left wall blooming yellow flowers. Wall-run it, hang left, slide under a rock overhang into a tunnel—the Gourdy's at its end.
Mission #9 – Execute the troublemaker (Target Area: Fuuhaku Sanctum)
Still in the caves, reach a big zone with a left-end temple. Skip it, go right, and hit the wooden door. The troublemaker's in the next spot.
Purgatory Gate #5
After raiding a ruined temple for a chest inside, move to the next area and the ravine jump. Drop into the valley below instead. Follow back to the main until stairs lead to the next purgatory gate.
Mission #10 – Execute the rampaging daemons (Target Area: Fuuhaku Sanctum)
In the big courtyard between temples, hit the right side and roof-jump. Push straight through a mountain passage, flying bird flip up a cliff. Up top, a giant tree rings with the rampaging daemons—clear 'em.
Accessory #2 (Ashen Pipe)
In the four-temple zone, climb the middle stairs. Under the ahead temple's roof, smack the rope to ring the bell: once for first hidden chest, three more to spawn and kill enemies, fifth for the second chest with the accessory.
Gourdy #6
From that last accessory and bell, face the temple and turn right—look up for a Caddis Wire spot and wall-run to the next Gourdy. Watch it: blue one, so no-spot catch.
Accessory #3 (Crimson Ring)
During the Dragonfly Glider run, you skim a canyon with wooden platforms and an end wall-run back to the air stream. Instead, leap to the two right-side poles. Caddis Wire the gap to a ledge chest with the ring.
Mission #11 – Retrieve the heirloom knife in Fuuhaku Sanctum (Target Area: Fuuhaku Sanctum)
After another Dragonfly Glider stretch, in a canyon with two tengu scraps and eventual fireball shots from a big metal teapot enemy. Head over, kill the teapot—the heirloom knife glows blue behind it on the ground.

Right post-boss, exit the arena and swing left. It's in the ahead corner.
