On the back of the large pillar that is behind the starting point after being digitized.

1. After the first data stream when entering The Nexus from Deck 13 1/2, on the back of the advertisement on the eastern side of the room.

2. On the underside of Positive Terminal, near the glitched chest. To get there you need to jump down to the lowest level in the southern part of the Terminal.

3. In a hidden area underneath the atrium just before the final data streams. Fall down and to the right a couple times from the jump pad that leads to the atrium.


4. On the roof of the atrium just before the final data streams. You can get there either by falling down from the "end" of the map or climbing on a strut from the ground floor.

On the fence of a platform atop tall support beams beside where Dr. Zed's projection first appears.

1. On the far side of a trash box that's between two buildings near Dave's house.

2. On the cliff beside a chest on a small outcropping beside Gubbin's Shack.

3. On the wall inside the shack located between the church and Overlook.

Hitting all three slam pads within a certain amount of time will unlock the door of the shack in the southwestern part of the town. You will complete the challenge "Faptrap" upon entering it.
***NOTE*** You can slam pads in any order but the following is suggested as the easiest to solo.

1. The first slam pad is on a small outcropping beside Dave's house.

2. The second slam pad is behind the rock in the northwestern part of the floating island where Gubbin's shack is located.

3. The third slam pad is on a small outcropping beside the church.

4. Claptrap's hidden room.

***NOTE*** These aren't linked to any challenge, but have tiny bit of a Tassiter's side story.

1. The first ECHO lies on the prop of the building to the right as you just enter the town of Overlook.

2. The second one is on the trash container to the right of the Claptrap's place.

1. On the top of a support beam above the entrance/exit to the data streams leading back to the exit to The Nexus, in the Data Splitter area.

2. After passing the shops near the exit to Cluster 99002 0V3RL00K, on the outside of the wall behind the shops.

3. On the platform above where a Jump Pad is extended during the mission "The Psychology of a Claptrap". The platform can be accessed either by grenade-jumping from the Jump Pad platform or by performing air boost while airborne after stepping on the said Jump Pad.

4. To the left of D1GN1TY-TP, on the floor.

5. On the roof of a structure on the yellow data stream back from Memory Bank 2 to The Confluence. This symbol is only accessible by gravity slamming from the yellow data stream down to a thin spur between two struts (before the usual walkable platform reachable via Jump Pads), and then walking up the strut to the ceiling. The slam is difficult to time correctly, and can either result in death (if triggered too early) or overshooting and landing on the platform (if triggered too late).

The chest can be found in Memory Bank 2, just before the exit to Cluster 00773 P4ND0R4. It is reachable by climbing either of the two struts above the vertical Data Streams, and walking across the large cables.

***NOTE*** These aren't linked to any challenge, covering backstory of a Davis Pickle. For some strange reason there are six ECHO's on the map, three of them beign duplicates.

1a. First ECHO can be found on the second floor in the Security Station area.

1b. The platform between Data Splitter and Memory Bank 2. On the computer console behind the pillar.

2a. On the third floor of the Data Splitter area. Take the left Jump Pad right after you pass Claptrap's hologram.

2b. On the top of a nearby strut. Can be easily acessed from the fourth level (which will be open to you during the mission "The Psychology of a Claptrap").

3a. The platform between Data Splitter and Memory Bank 2. On the crates.

3b. Attached to the door on the platform which is transitional to the one D1GN1TY-TP is on.

To complete this challenge, the Vault Hunter must ride all eight Data Streams from start to finish without leaving the map. Partially-ridden Streams do not count.
***NOTE*** Since the streams are made active as part of the quest progression, this challenge is only completable once the path to Cluster 99002 0V3RL00K has been opened, during the quest "The Psychology of a Claptrap".

1. After dropping into Despair and Self-Loathing's arena, on the back wall behind the descent.

2. On a platform beside a glitch chest just after entering the Sub-Subconscious, before entering Deception Hall.

3. At the farthest end of the bridge leading to the exit to The Cortex, on the second upside-down pillar.

1. Hidden inside of the cuddle bears pile.

2. On the ledge, hidden behind the wall. On the second floating island near the statue of a Claptrap which you will visit on the course of "Temple of Boom" mission given by Tannis.

3. Beside a pillar on a raised square platform in the western part of the room.

4. Subliminal Plaza. It's in the water pool on the wall to your right as you enter the area.

5. Above the exit of the shrinking-hallway optical illusion. Perform an air burst to jump there.

At five locations in the first area of Subconscious (before the Sub-Subconscious section), bubbles will be floating up from down below. In each stream of bubbles, occasionally one will be larger than the rest and have an image of a character's face inside it. Popping those bubbles with any damage-producing source will cause Claptrap's voice to give a line of dialog about his thoughts on the character in question. Popping all five of these bubbles will cause the challenge to complete.

***NOTE*** These aren't linked to any challenge. Only flavour.

1. Chimera Island. On the ledge above the first bear.

2. On the first of Triplex Islands. On the ledge ahead of you past the gates.

3. On the ledge of the tiny floating island in between Triplex Islands and the Terrorhead Gorge. Right next to Nina bubles.

4. Above the saving point in the Terrorhead Gorge (the place where you rescue Hope and Self-Esteem).

5. Right before you drop down to Sub-subconscious, near the entrance.

High up on the left side of the same wall as the exit to Subconscious.

Underneath the ramp leading to the jump pad to 5H4D0W-TP's throne. You need to walk on charred earth in order to get this.
