My Brother's Keeper is a hidden trophy/achievement in the Zombies mode map Der Eisendrache that appears in Call of Duty: Black Ops III. It is the main easter egg of the map, and it requires the player to "erase" the original "Tank" Dempsey. This also requires to continue on with Richtofen's plan, purging Group 935 and Groph, as well as blowing up Griffin Station and the Moon. It is possible to complete this easter egg with any number of players, including solo.

PrerequisitesEdit

Before starting the easter egg, at least one Wrath of the Ancients bow must be upgraded.

Throughout the course of the easter egg, the following will be required:

  • For every player in the game, one bow must be upgraded; for example, in a solo game one upgraded bow is sufficient, while with four players all bows must be upgraded
    • If playing in a non-ranked private game, all bows must be upgraded regardless of the player amount
  • Ragnarok DG-4
  • Death Ray activated at least once

Step 1: Shooting the beaconsEdit

Go back to the tomb area and retrieve the original Wrath of the Ancients. Now, go to the teleporter room and shoot each of the beacons/rods at the top of the teleporter. The player needs to shoot each one so that its end turns orange. Once the player lights them all up, the orange glow will disappear, the sound of a Margwa growling is heard, and the player will be able to move on to the next step.

Step 2: Shooting the sparksEdit

Around the map there will be random objects that could possibly be sparking. Only one object will be sparking at one time and the player will hear a cue (a Margwa growling) before it starts to spark. Shoot the sparking object with any upgraded bow and it will stop sparking. Shooting with anything else, including the original bow, will result in an instant failure.

The player will hear another cue and have to repeat this process three more times. Keep in mind that after the first try, the process will automatically start at the beginning of each next round until completed. After four sparking objects have been shot, the player will hear a different cue indicating they have completed this step. If the player takes too long or messes up, they will hear a failure cue which resets progress on the step and is unable to be resumed until the next round. Below are the locations of the certain sparking objects.

Possible locationsEdit

  • Phone near Quick Revive
  • Car tire near Double Tap II
  • Box near work bench above Double Tap II
  • Globe in small room besides Samantha's room
  • Phone on pillar near power switch
  • Clock in the hallway connecting the clock tower and church
  • Radio in the adjacent corner from Speed Cola (the one close to the entrance)
  • Clock above fireplace in the church

Do note that if the player shoots at one of the possible locations while it's not sparking, it will also count as an immediate failure.

Step 3: Time travelEdit

Note: All of this step must be completed within the same round. If the step is failed at any point, they can redo step 2 and restart this step on any following round.

Return to the teleporter and the bottom light will have turned purple. All players in the game must be in the teleporter in order to teleport.

Once the player teleports, they will now be in the same room but it will be cleaned up and obviously in the past. Here, the player cannot use their weapons or equipment. Dr. Groph will be here talking to Richtofen over radio and accessing his safe. Here the player must do three things before they are teleported back:

  • Hold the use button to pick up the glowing blue canister in the corner of the room near Dr. Groph.
  • Hold the use button to pick up the fuses to the right of the teleporter (left if the player is looking directly at the teleporter), on top of a box.
  • Remember the three symbols that appear on the vault (from top to bottom) after Dr. Groph locks it. There are four possible symbols: a lightning bolt, a rectangle with a half-circle in it, a circle with dots in it, and a diamond-like shape with an up arrow on it. These symbols change each round; memorize them each time you travel to the past should you fail this step.

After a while, the players are teleported back to the present at the rocket site, where a Panzersoldat will appear regardless of the round (except on the PS3 and Xbox 360 versions). It will appear each time travel during the easter egg. It might not appear if the rocket test fire takes place or has just finished as the players arrive, however.

Interact with the Death Ray on the side facing away from the clock tower to add a fuse to the side, then go to the other side and pull the lever to switch the Death Ray from "Destroy" to "Protect".

The Death Ray must have been turned on at least once in the game in order to proceed. Head to the terminal near the clock tower and enter the three symbols from the safe the player memorized in order from top-to-bottom. This will open the safe across from the teleporter (the same safe seen in the past). If the code is input incorrectly, steps 2 and 3 must be redone.

Step 4: Memory gameEdit

Head to the safe and interact with it to pick up the two fuses and the keycard. Insert each fuse into the Tesla coils on either side of the Death Ray where there are only two electric currents, then return the Death Ray to "Destroy" mode (no activation is required). Head to the terminals outside of the clock tower or on the rocket pad and interact with them. This activates a memory game.

The four symbols on the bottom screens will show for a few seconds before disappearing. Memorize the symbols' locations, or screenshot them for reference. The top screen will then show a symbol and the player must interact with the screen correlated to that symbol. Do this a number of times until the machine shuts down and the player hears an audio cue.

Repeat the game at the other terminal (at the rocket pad or outside the clock tower, depending on which you did first). If the player fails the game they can instantly restart the game by interacting with it again. Note that if the player fails the game at their second terminal, they will have to replay the game at both terminals.

In co-op, hellhounds will infinitely continue to spawn while a player is interacting with the terminals.

Step 5: SabotageEdit

The orbs atop the Tesla Coils will now be glowing. Interact with the green button on the back of the death ray to initiate the rocket crash. A rocket will appear in the sky and fly across until striking the bell tower (destroying the bell) and landing in the courtyard below. Dr. Groph will express his anger and lock down the cryogenically frozen "Tank" Dempsey with a lightning barrier, prohibiting the player from interacting with it. If they touch the chamber, they will be hurt by electric damage.

Step 6: Getting the MPD from the MoonEdit

Next to the crashed pod, there is a Vril Generator sitting in the snow, pick it up.

The player will need to teleport back in time again to find an item they could not access before, by reenacting step 2; every round after the initial teleport will play a Margwa sound at the beginning signaling a spark has spawned.

Once in the past again, hold the use button on the book (Kronorium) that is sat in a crate on the right side of the room. A case near the doorway will then open, revealing a stone tablet with the Keeper symbol etched into it. Pick it up with the use button and wait to teleport back.

Place the Vril Generator in the slot on the side of the tomb (in front of the location where the player obtained the Wrath of the Ancients) and a ghostly Keeper will rise out of the tomb. He will start traveling the map and stop at four separate locations in a random order: at the church courtyard, next to Mule Kick, next to Double Tap II and by the knight armors near the power switch. Note that when he stops by Double Tap II, the player will need to interact with the part of the wall to the right of the Keeper and under the lamp post to place the stone tablet. If this isn't done, the next part cannot be completed at this location.

For this part, all players in the game should have an upgraded bow (or more specifically, have at least as many bows upgraded as there are players, as mentioned in the prerequisites).

A white circle will appear at the location the Keeper stops at. When you stand inside the circle, there will be a colored tint around the screen. The color of the tint correlates to the color of a specific bow (e.g. a bluish tint means the storm bow). The player needs to get kills with the indicated bow whilst standing in the white circle. The more players that stand within the circle, the wider the circle's radius will become. Getting kills with the correct bow will transfer souls into the tablet, and once full, the ghost will move to the next location and repeat the process. The zombies do not have to be within the circle.

After this is done four times, the ghostly Keeper will become corporeal, as they appear in Shadows of Evil. It will travel to the Undercroft and teleport to the Moon, and after a brief audio cutscene (during which all zombies despawn), the Keeper will teleport the MPD from the Moon. The MPD has blue canisters in each corner, except from one corner. Place the soul canister the player picked up during step 3 in the corner of the MPD that is empty, opening it, revealing the same Keeper who has now been corrupted. (If the player did not pick up the canister on a previous step, they can travel to the past again the same way as before.)

Prepare for a boss fight which cannot be exited until it is defeated. Once everyone is ready for a boss fight, each player must take their Ragnarok DG-4s and use the trap function on one of the blue squares used to activate no gravity. The player will then be teleported into a new room.

Step 7: Keeper Boss BattleEdit

The battle arena is a circular dark room, with pillars surrounding the middle. Here the player will meet the corrupted Keeper, who is now gigantic and is the boss of this area. The boss fight has five phases, which differ from each other slightly.

Phase 1 Edit

The Keeper will currently have four attacks that mirror all four Ancient Bow abilities. The attacks are as follows:

  1. A rain of skulls that come down from the sky. If a player is hit by a skull, they will be stunned, slowing them down a little bit. The player can shoot the skulls before they hit a player to destroy them.
  2. Spawning in skeletons (which act like zombies).
  3. Summoning volcanoes that deal damage to the player (enough to down a player without Juggernog).
  4. A massive electric shockwave that instantly downs anyone who is touched by it. To avoid this shockwave, the player needs to stand behind one of the glowing blue pillars in the area.

The fourth attack is important as it gives the player an opportunity to damage the Keeper boss. Before the shockwave is unleashed, the player will see a ball of electricity appear beneath the Keeper in the center of the room. As soon as the player sees this electric ball, a player will need to run inside of the electric ball and place down their Ragnarok DG-4 as a trap. The player should then run back away from the electric ball.

Doing this correctly will plant the Keeper in the center of the room, and the rend on its chest will glow orange. The player now needs to shoot the rend to damage the Keeper. Once the rend ceases to glow, the boss can no longer be damaged.

The player needs to keep repeating this and, once it is done enough times, a Max Ammo will spawn in the center of the room. This indicates the start of phase 2.

Phase 2 Edit

In this phase, the Keeper boss will disappear, and after a very short while, multiple Panzer Soldats will spawn around the room. For this phase, the player simply needs to keep killing the Panzer Soldats. Note that the first Panzer Soldat that is killed here will drop a Max Ammo upon death. Skeletons will continue to spawn in this phase.

Eventually, a Max Ammo will appear in the center of the room and the Keeper will begin speaking. He will reappear after a few seconds. This indicates the start of the next phase.

Phase 3 Edit

This phase is the exact same as Phase 1, with additional Hellhounds spawning. Repeat the same process as Phase 1. Kill the skeletons and Hellhounds that spawn if you need to recharge your Ragnarok DG-4.

Phase 4 Edit

This phase is just like Phase 2. It will consist of Panzer Soldats and Skeletons.

Phase 5 Edit

This phase is the same as the first and third. In co-op, a Panzer Soldat will also spawn in each time the Keeper is about to unleash its electric shockwave. Repeat the process as in Phases 1 and 3. Eventually, the Keeper will let out one final scream, then spin around, signaling its defeat.

Step 8: Sky DestructionEdit

After defeating the Keeper, the player will be teleported back to the MPD. Here, Dr. Groph will express his extreme anger at the group and vows to destroy them and even going as far to state he will destroy the entire castle if he has to. On one side of the MPD, the player will see a glowing blue circle with a shape at the top of it that looks like the Vril Generator from earlier. Press the use button on the circle and the Summoning Key will appear. Pick it up after a few seconds.  

Richtofen will explain that the player needs to charge the key in order to free the test subject. Take the key to the terminal next to the Clock Tower (the one used earlier for the Simon Says game) and interact with the terminal. The Key will float above the terminal and beginning spewing out electricity violently. All zombies will despawn for the following cutscene.

At this point, multiple rockets will be blasted at the Moon. This will cause the destruction of the Moon, killing Groph and any other Group 935 members at Griffin Station. A cutscene will then play.

CutsceneEdit

The cutscene features the four characters (Richtofen, Dempsey, Takeo and Nikolai) walking up to the cryogenically-frozen Ultimis Dempsey, noting that he is still alive. At this point, Richtofen pulls out the Summoning Key and it begins to glow. This causes Dempsey, Takeo and Nikolai to float above the ground, out of their control. Richtofen says to them that the cryogenically-frozen Dempsey "will one day wreak havoc across the entire universe", and that he cannot be allowed to live. This makes Dempsey angry, and he begins to shout at Richtofen, stating they were supposed to "secure the package and be in and out clean", and that he shouldn't have trusted him. Richtofen then says that the Summoning Key will store the cryogenically-frozen Dempsey's soul, but that it can only be done after he dies. Richtofen then turns to kill the Dempsey inside the container, but Dempsey quickly shouts, saying that he should be the one to do it. Richtofen then releases Dempsey, and he walks up to the container, looking at his body inside. He mutters "good to see you, Tank" before switching off the container, killing the Dempsey inside. Richtofen then absorbs Ultimis Dempsey's soul into the Summoning Key.  

Afterwards, all players are given all of the perks on the map (Quick Revive, Juggernog, Double Tap II, Speed Cola, Mule Kick, Electric Cherry, Widow's Wine, Stamin-Up and Deadshot Daiquiri) and are given a brief period of damage immunity. This will also cause the achievement/trophy to unlock for all players who completed the steps. It will also give a bonus 2500 XP (for which the reward title is "Frozen Freedom") and a Gateworm icon on the map selection screen.

TriviaEdit

  • The title of the Easter egg is a reference to the story of Cain and Abel from the Bible. In the Bible, God asks Cain, "Where is Abel thy brother?", to which Cain replies, "I know not: am I my brother's keeper?"
