ECHO - All Voices and Cell Locations

A guide for getting all collectibles in the game "ECHO" by ULTRA ULTRA.

Basic Information

ECHO is a stealth game that features enemies who continually adapt to the player by "echoing" their actions.

Although the game is relatively short and not overly difficult, the level design/aesthetic and lack of directional aid (such as a map or collectible markers) can make going for 100% completion a nightmare. Thankfully, I've listed all of their locations here and given a simple description of how to get them.

Be aware that you will need to play through the game a second time on Ultra Hard Mode to obtain the final achievement. I recommend using this guide on your first playthrough on Normal, to minimize frustration.

There are 3 main collectibles in the game:

1. Voices — These are the tuning fork things that you find on tables throughout the game. Pressing E will strike it and collect an audio message. The fact that they are so small means they blend into the environment extremely well, but you can often see them during blackouts because they have a distinct white glow when untouched.

2. Cell Crystals — These are the triangular crystals suspended in midair that give off a faint green glow. Hard to miss once you've seen them. Collecting these gives you progress towards another energy point, as indicated by your HUD.

3. Caste Orbs — These are the blue orbs that appear at the end of every chapter before you ride the caste elevator. The number of orbs you need to unlock the elevator is indicated on the right side of the red cube, and the total number of orbs in the level is indicated on the left. If you plan to get every achievement, grab all of the orbs even if the elevator is already unlocked. I won't list all their locations here, but I will try to list all the locations of the Save Archways that I am aware of. Standing inside a Save Arch reveals all caste orb locations.

Another warning: there is a missable achievement called "Outsourcing" that requires you to collect a voice by having an enemy interact with it. Check out one of the other ECHO guides or a YouTube video for detailed instructions on how to do this. If you don't get this achievement before collecting all voices, you will need to create a new save file and play all the way to Chapter 3 since voices are collected permanently after you save your game, even upon restarting the level.

Before I list all of the collectibles, here are some gameplay tips that can save your life while going for 100%:
- This is a stealth game, not a shooter. You will have an easier time if you avoid fighting the clones head-on.
- The clones forget your moves from before the most recent blackout cycle, so a viable strategy is "run and gun > stealth > run and gun > stealth" and so on.
- You can do various things to force a blackout: tap R twice (whisper), hold R twice (shout), press E twice on a tuning fork, eat grapes, vault repeatedly, open and close doors repeatedly, et cetera. The clones will forget everything and be practically useless the next cycle.
- You can forcefully despawn a clone by killing them during a transition from night to day. You get an audio cue during this time right before the screen goes black (it's like 5-6 seconds long). I do not know if this causes them to go away permanently, or only for one cycle.
- Do not bother trying to shoot the golden clones in Chapter 6. There are too many and they have too much health. Just hide or run past, but take them out immediately if they spot you since their grab is an instant kill. Use Save Archways as necessary.
- If you want to speed up the collectible hunting slightly, one thing you can do is teach the clones to strike the tuning forks as mentioned above. This is unlikely to work, but possible. I have had it happen to me.
- Using a Save Arch during the caste levels preserves your current orb count, so use this as needed when you are going for the total amount of orbs.

CHAPTER II - GENESIS

Chapter I has no collectibles, so we begin here.

Total Number of Collectibles:
Voices: 19
Cells: 2
Orbs: 17

Voice #1:
Once you enter The Palace and explore for a few minutes, you will need to jump over a railing to progress. The voice will be directly in front of you.



Voice #2:
After striking the first voice and entering the next room, the second voice is immediately on your right.



Voice #3:
In the same room as the second voice, go to the other side and you will see a wall of mirrors. The third voice is at the end of this wall of mirrors.



Voice #4:
Watch a cutscene and you will enter into a giant green hallway that loops forever. Jump over the railing to progress, and a voice will be right next to you.



Voice #5:
After collecting the previous voice, go forward and En and London will banter some. Walk down a winding staircase, and at the bottom of these stairs, there is a voice behind one of the gigantic vases.



Voice #6:
From the previous voice, go down another stairway and into another hall with green lighting. On your right, there is a voice hidden among many tables and chairs.



Voice #7:
Keep going and you will see an enormous throne. The next voice is on the opposite end of the hallway from where this throne is, hidden in a corner.



Voice #8:
Once The Palace wakes up, go down a long corridor with flashing lights. You will get a new waypoint on your HUD. Ignore it and go the opposite direction, and you'll see an unlocked door. Follow this hallway and you'll see another unlocked door on the left, which contains a voice.



Voice #9:
Continue progressing until you reach a maze of unlocked doors. This voice will be in the first room of this door maze.



Voice #10:
Hug the right side of this door maze, and you will find this voice in a nearby room.



Voice #11:
After encountering the first clone that wants to kill you, this voice is on the right side behind a pillar.



Voice #12:
After the gun tutorial, you unlock a door with a scepter. Go past this door and on the right side, before going downstairs, there is a voice in a room full of chairs.



Voice #13:
This voice is immediately after the area scan tutorial, in the hallways packed with clones. It is behind one of the squares in the middle row. You can shout (R) to lure clones away from it.

After the riot gun tutorial, there will be a large hole in the floor with a railing in front of you. On the opposite side of this hole is an unlocked door with a voice behind it.



Voice #15:
Go back through the door you just used, and head into the open area on the right. There is a scepter hidden in the corner here. (If you've jumped over a railing at this point, it means you went too far.)



Voice #16:
Progress through the level, and you will jump over a railing and need to run past many clones on a large balcony. At the end of the balcony room, there are several clones guarding a power source. The voice is hidden in an unlocked room on the left side of this power source.

After the previous voice, you will jump over a stone barrier and start leaving behind holograms. This voice is in an unlocked room right next to this stone barrier.



Cell #1:

Caste Orbs:
Here you will encounter your first caste orb. You need 10 to unlock the elevator, but 17 total in this level to unlock an achievement. There are no save archways in this level to show you where the orbs are, so just run around the arena until you find them all. Feel free to sprint and shoot, since the clones cannot copy that functionality yet. You can run circles around them if you want to.



Voice #18:
When entering the caste orb area, this voice is in the far back right corner, behind an unlocked door. You will need to go up some stairs to get there.

Final Thoughts

Thank you for reading, if you made it this far.

I really liked this game. I think it gets a slightly unfair rep from people who weren't patient enough with it, or misunderstood what the game was trying to do with the gameplay. I don't see myself ever replaying it, but I think with some more development time and polishing, this game could've been something really special.

Nevertheless, I hope this guide served you well and I hope that my navigational descriptions weren't too vague. Good luck on Ultra Hard Mode!
