'Destiny 2' All Mars Lost Memory Fragment Locations to Get Worldline Zero
Destiny 2 's Warmind expansion has 45 Lost Memory Fragments that players can collect to unlock an Exotic Sparrow and a Worldline Zero Exotic Sword. This guide is a long one, but we've divided it by location to make it a bit more digestible.
OLYMPUS DESCENT LOST MEMORY FRAGMENTS
Fragment 1: South of spawn down the single path. You'll see a mine under some ice. Behind and just below is the Lost Memory fragment. Shoot with any weapon.

Fragment 2: Continue down the path and you'll see a large chasm to the right. The Lost Memory fragment is on the cliff here.

Fragment 3: The third cache is on the edge of the map. Go south from there till you get outside. The fragment is next to a cliff. You'll have to look up high to see it.

GLACIAL DRIFT LOST MEMORY FRAGMENTS
Fragment 4: Once you get here, turn around. The fragment is buried in the cliffs behind you.

Fragment 5: You need to go down towards the guardrail near the bridge. Under the guardrail is a fragment tucked in a corner.

Fragment 6: In front of the Lost Sector just behind fragment 5. It's tucked in a ledge. You may need to shoot it with a Solar weapon.

Fragments 7+8: Go inside the Lost Sector and follow the path When you get to the open area with the pit, there are two of them here. One tucked in to the left, and one below where the cave mouth opens up. You may need to walk around the other side of the pit to see it.

Fragment 9: On the opposite side of the Lost Sector is a hangar. The fragment is right where these lights are.

Fragment 10: Inside the hangar in this spot here.

Fragment 11: Exit the hangar and take a right. This will put you between Drift and Braytech near the trains. It's in the corner by this big fan, and it must be shot by a Solar weapon.

Fragment 12: On the bridge you'll see this Clovis Bray sign. The fragment is on a little platform to the right of it.

Fragment 13: Get to the top of "C" and "I" in Glacial Drift and you'll come to a bridge. Tucked under the bridge is a fragment that must be hit with the Valkyrie Escalation Protocol weapon. For more info on how to get one, read our Armory Codes guide.

Fragment 14: It's sort of on the opposite side of the "C" and "I." It's in this very obvious tree and also requires a Valkyrie.

Fragments 15+16: Southeast of fragment 14 on the coast. Get to this point on the bridge. One is tucked in the cliffs, the other is directly to the left of it on the roof of the building.

Fragment 17: In the building you just shot. It's tucked in this room with the big crate.

DYNAMO APPROACH LOST MEMORY FRAGMENT LOCATION
Fragment 18 : This is east of the "H" where the terrain starts to narrow. From here you can snipe this big tower.

ALTON DYNAMO LOST MEMORY FRAGMENT LOCATIONS
Fragment 19: Start on the east coast of this area, north of the "H" in Approach. It's on the entrance path to the left of this spot.

Fragment 20: Still on the entrance path. When you get here, it's on the left edge near the handrail. It requires a Solar weapon.

Fragment 21: From there the path forks, so take a right. In the back-right area of the room is this tall pillar. There's a Lost Memory fragment on it.

Fragment 22: Backtrack to the left path. There's a vent in the top-right of the room. To get inside it, jump on the nearby pipe. The vent opens to a room with a terminal you must interact with to get fragment 26 later. Go back the way you came and pass through the large door. In this room is a glass opening you must shoot and jump through. Inside the area where the glass was is a Void Lost Memory fragment.

Fragment 23: From here go left and keep following the path. Pass through a couple doors and you'll reach this ledge. Hop on top and a fragment is on the cliffs to the right.

Fragment 24: To the right on the other side of where you were is a very large metal beam. There's a Lost Memory fragment on it between the icicles.

Fragment 25+26: Assuming you've activated the terminal from fragment 22, go through the door and shoot the pretty obvious fragment on the machinery to your right in the next room. Across from that fragment is a door that flashes between opened and closed. Interact when it's blue, and the door will open to reveal a fragment.

Fragment 27: In the boss room, look towards the ceiling to your right for another fragment.

BRAYTECH FUTURESCAPE LOST MEMORY FRAGMENT LOCATIONS
Fragment 28: Behind Ana Bray's window.

Fragment 29: Behind you from that location is a balcony with a staircase and a big, orange tank. On the tank is a fragment you must jump to. Shoot it with a solar weapon.

Fragment 30: Jump to this building and get to its highest point. From there you'll see a bunch of tanks. Shoot the white light coming from them. It's another fragment.

Fragment 31: On the opposite side of that location is a bridge with pipes. The memory fragment is just beyond these pipes to the right. It requires a Void weapon.

Fragment 32: Fast Travel to the Braytech spawn. A fragment is on the top-right corner of this building. It requires a Solar weapon.

Fragment 33: On the opposite side of that building shown here. You need to get a Valkyrie to collect this fragment.

Fragment 34: This fragment is basically on top of the "R" and "E" in Futurescape. It's between the two buildings shown here.

Fragment 35: Across from the previous fragment is a button to interact with. Do so and pass through the building entrance labeled "02." Inside and up the stairs to the left is another fragment.

NOTE: If you've followed the guide up to this point you can now go to the Core Terminus sector to get the Worldline Zero Exotic sword. However, there are only ten more to go till you can get both the Sword and Sparrow.

Fragment 36: A fragment is on a box to the right of the Clovis Bray sign in the Bray building.

Fragment 37: Go towards the staircases on Ana's right, and you'll find one on the large Rasputin statue in the foyer.

CORE TERMINUS LOST MEMORY FRAGMENT LOCATIONS
Fragment 38: Halfway down the Lost Sector you'll see this door. Interact with it and it will open to another fragment. It requires a Solar weapon.

Fragment 39: At the bottom of the sector refrain from killing the boss. You'll see this partially open door with a fragment behind it.

AURORA REACH LOST MEMORY FRAGMENT LOCATIONS
Fragment 40: Back at the Rasputin statue from fragment 37, go up the stairs and you'll see this fragment tucked away. You may have to crouch to shoot it.

Fragment 41: On that same path, you'll find another fragment on this box. It requires a Void weapon.

MINDLAB: RASPUTIN LOST MEMORY FRAGMENT LOCATIONS
Fragment 42: On the path from the previous location, you'll see a fragment on a glass panel. It requires a Solar weapon.

Fragment 43: Get outside and jump off on the pipes to the right. Follow the pipe and you'll come to this point where it breaks slightly to the right. Fall onto that ledge and a fragment is just ahead.

Fragment 44: Get back on the main Mindlab questline and hop over all the yellow energy in the center of the room. You'll see this doorway with another easy fragment.

Fragment 45: Before you enter Rasputin's room, the last fragment is here near the door. Use a sniper to get it.

NOTE: To get the Sparrow, go to where you found the first fragment. The cache is buried in a nearby cave. You have to jump down to get there.
