Ninja Gaiden 4 contains 18 Purgatory Trials. Completing all Purgatory Trials unlocks the Annihilator trophy & achievement. Finishing all of them is required for the Challenger of Challenges trophy & achievement. Purgatory Trials are accessed through Purgatory Gates in different chapters. Each chapter has one Purgatory Trial, except Chapter 14 which doesn’t have one. There are 19 Chapters total but only 18 Purgatory Trials. You have to finish the Purgatory Gates during the story playthrough, not through the Challenge Menu. Completing them in challenge section of the main menu will not unlock the Annihilator trophy!
The videos below are on Master Ninja difficulty.
For the Challenger of Challenges it has been confirmed that finishing them on the lowest difficulty “Hero” is enough. Playing boss trials on “Hero” is also enough for the all challenges trophy.
Chapter 1
Purgatory Gate #1: Just before you have to use the Caddis Wire for the second time to jump over a gap between buildings, turn left to see three dump trucks parked next to each other. Simply run past them and turn left in to a an alley where you can use the flying bird technique. Once you are up on the roof, the gate is located right in front of you.
Chapter 2
Purgatory Gate #2: Once you enter the stage with the flying D.D.O. enemies and the drones, use the Cadis Wire to scale the large building in front of you, turn right and make your way through the blue shipping containers, to get to a different monorail track in a broken down building. The track does not glow orange. Skate on the track until you have to jump off and simply make your way up some stairs to find the gate.
Chapter 3
Purgatory Gate #3: After using the flying bird flip to get up the shaft right after the beginning of the mission, turn around and follow the alley instead of crossing the bridge in front of you as you would have to for the main story path. The gate is located yet again in a dead end.
Chapter 4
Purgatory Gate #4: Making your way through the canyon with the Caddis Wire, you will end up on a narrow cliff and you are meant to use the flying bird flip to scale a rock wall, however turn around and walk away from the mission path. Following this narrow path you are on will lead you to the gate for this chapter.
Chapter 5
Purgatory Gate #5: There will be a section with the ruin of a temple that you can access and find a chest inside. Moving onto the next area, you are meant to jump over a revine, however simply jump down into the valley right below it. Down there keep following the path back to the main mission until you find the next purgatory gate at the top of a small set of stairs.
Chapter 6
Purgatory Gate #6: After finding a set of shops, you will use the Dragonfly Glider very briefly to land on some wooden platforms in a canyon. Instead of proceeding left, use the Caddis Wire on the right to swing across the gap. Follow the path until you end up at the next purgatory gate.
Chapter 7
Purgatory Gate #7: At the start of the chapter, follow the stairs down to the right instead of going up the stairs of the main path. Once you reach the end of the path, you will find a purgatory gate and a gourdy sitting right behind it.
Chapter 8
Purgatory Gate #8: After you cleared the room with the two enemy spawn portals (a bit after unlocking the Pond Strider), walk through the door into the next area. Instead of going left, go right around a hallway, then use the flying bird flip and finally the Pond Strider to surf along a pipe. You will end up on a room that has the 8th purgatory gate of the game.
Chapter 9
Purgatory Gate #9: Once you get to the area you can freely explore with your Pond Strider, simply jump into the water from where you start and surf along the left side of the area until you get to the entrance of a cave. Inside that cave you will find the purgatory gate at the end.
Chapter 10
Purgatory Gate #10: You will start the mission in a tunnel with two stores and a few enemies you have to kill. Once you have killed them, take the optional path to your right past the stores, instead of staying in the main tunnel. At the end of this hallway, you will open a door and find the gate in the area you just unlocked.
Chapter 11
Chapter 12
Purgatory Gate #12: In the area where you fought the two D.D.O. heavy enemies (one with a launcher and a melee one), turn left and swing alongside a Caddis Wire section. On your optional path, keep going straight and then through a door. The gate is located up the stairs in the next room.
Chapter 13
Purgatory Gate #13: At the very start of the chapter, turn around and walk down the stairs. Turn left and use the Caddis Wire to get up onto a walkway above you. Go left again and use two more Caddis Wire points to get onto a railway track. You will have to do some rail-surfing and wall-running to get to the end, where you will find the gate right in front of you, up a flight of stairs.
Chapter 15
(Chapter 14 doesn’t have a Purgatory Trial)
Purgatory Gate #14: The gate is located on the left platform, in the same room as the previous collectible.
Chapter 16
Purgatory Gate #15: In the area with the massive doll head in the sky, turn to the right and follow the way past a shop. You will have to perform a wall run and jump over a few gaps, but just keep following the path until you hit a dead end. Here you will find the next purgatory gate. This is the exact same location as in Mission #1.
Chapter 17
Purgatory Gate #16: At the start of the chapter, take the optional path to the right instead of going up the stairs. Use the Caddis Wire and then jump to the next platform. At the end of this path you will find the next purgatory gate.
Chapter 18
Purgatory Gate #17: You will get to a white cube shaped room with pipes on every wall. The main path leads you up a staircase, however you want to go through the metal barricades on your left. At the end of this short hallway, you will find the second to last gate.
Chapter 19
Purgatory Gate #18: Same location as gate #17, only difference is that you are now playing as Yakumo and not Ryu.
