"Call of Duty: Black Ops 3" final expansion pack has received new stops for the game from Treyarch, the developer. Players need to unlock the first three maps apart from the Zombies map titled "Revelations" to complete the Easter Eggs.
According to GameRant, "Revelations" is the final Zombies map from Treyarch for at least a few years making the studio go all out and pack the map with one of the most elaborate Easter Eggs in series history.
Before tackling the Easter Egg, "Call of Duty: Black Ops III" players should take some time to familiarize themselves with the new Zombies map. It is best if players can manage to assemble a team of friends to assist them get through all the steps and tackle these Easter Eggs, but it is possible to complete the entire 'A Better Tomorrow' Easter Egg individually as well.
Turning on the power in a Zombies map is the first step which is a pretty simple affair, but a little more complicated on the "Revelations" map. To enable this, players have to activate four separate generators called Corruption Engines, instead of just flipping a switch. The engines can be easily recognized as they exclude blue energy.
The four sections where the players will find the corruption engines are Mob of the Dead, Der Eisendrache, Starting Point, and Verruckt. The players will need to stay near the Corruption Engine and kill all the enemies that spawn but only after spending 500 points to activate one of the corruption engines.
Near the spawn point where the Corruption Engine is, players can spot some tombstones floating just outside the map. There are four tombstones in total representing the four original Zombies characters. These tombstones need to be shot in a specific order as follows: Takeo, Richtofen, Tank Dempsey, and Nikolai. If this is done in the correct order, a symbol will start glowing on them, Gamepur reported.
In the next step in the Easter Egg, players have to spawn a Keeper. The first part is to collect the parts required to build a summoning altar. These parts appear in random locations in Origins, Mob of the Dead, Verruckt, Kino der Toten, and Der Eisendrache sections of the map.
Upon collecting these parts, take them to one of the designated areas around the map and build the summoning altar. Players should make sure they activate the Juggernog for their character.
After summoning the Keeper, the next step is for the players to find a triangular blue rock on one of the jump pads. Bring the Keeper to the rock and it should start the ritual. This takes some time, hence, players should stay near the Keeper and protect it from the fresh swarm of the zombies that will spawn.
Once the ritual is complete, players should grab the audio reel that appears in the Keeper's place, deliver it to the recorder at "Nacht der Untoten" and listen for some interesting story details.
The final step will be to reach the Pack-A-Punch machine, which happens to be inside a giant, Lovecraftian beast known as the Apothicon. After activating all the four Corruption Engines, the player needs to head to "Nacht der Untoten" and go upstairs to the terminal there. Then, the player should wait for the Apothicon to move in front of the terminal to activate it.
