Preparing for the Solo Undertaking
Before you even think about starting the main quest, your first priority is survival and setup. The map is unforgiving, and a solid early game is non-negotiable. Your goal in the first few rounds is to establish a foundation of points, open up essential areas of the map, and acquire a reliable starting weapon.
Essential Starting Strategy (Rounds 1-5):
- Point Hoarding: Avoid killing zombies instantly. Use your starting pistol (MR6) to shoot each zombie in the leg once or twice, then knife them for a 130-point kill. This maximizes your points early on. You should aim for at least 5000 points by the end of Round 4.
- Map Access: Your first 1000 points should be spent on opening the door from the starting room (Footlight or Waterfront district). Immediately buy the RK5 off the wall for 750 points; it’s a fantastic point-building weapon.
- The Beast Mode: Activate the first purple symbol you see to enter Beast Mode. This is your primary tool for opening the map efficiently. In Beast Mode, you can break barriers for free, activate power switches, and pack-a-punch machines. Your objective is to turn on the power and open the path to the Pack-a-Punch machine as quickly as possible. A good solo time is to have Pack-a-Punch unlocked by Round 6 or 7.
- GobbleGum Strategy: Your GobbleGum loadout is critical. For a solo run, consider these essentials:
- Perkaholic or Soda Fountain: To get all perks instantly.
- Shopping Free: Opens all doors for free, saving thousands of points.
- Immolation Liquidation: Increases your chances of getting a Wonder Weapon from the mystery box.
- Near Death Experience: Essentially gives you unlimited revives for three rounds, which is a lifesaver during the final boss fight.
Acquiring the Wonder Weapons and Shields
You cannot complete the Easter Egg without specific tools of mass destruction. The Wonder Weapons are not just helpful; they are mandatory for several steps.
The Apothicon Servant and the Civil Protector: The Apothicon Servant is a wonder weapon that creates a black hole, sucking zombies into oblivion. It’s invaluable for crowd control. To build it solo, you need to find and shoot three xenomatter parts around the map with the upgraded sword (see below). The parts are in random locations, but common spots include the underground bunker and the Ruby Rabbit poster. Once you have all three, take them to the workbench in the Waterfront district. The Civil Protector, a giant robot, can be called for 1000 points once the power is on. He is crucial for one of the flag steps.
Building the Ragnarok DG-4: This is your specialist weapon and is essential for progression. The steps to build it are involved:
- Obtain the Sword: You must first acquire the Apothicon Sword by completing a ritual in each of the four main districts (Canals, Waterfront, Footlight, Junction). Each ritual requires you to protect a flag from zombies for a set duration. This is one of the most challenging steps solo.
- Upgrade the Sword (Keeper Protector): Take the sword to the pack-a-punch machine in the Footlight district and upgrade it. This costs 5000 points.
- Charge the Ragnarok Parts: You’ll find the three Ragnarok DG-4 parts scattered around the map. You must take each part to a specific location and use the upgraded sword to charge it by killing zombies near it. The locations are the rocket test site, the underground bunker, and the pack-a-punch room.
- Assemble the Ragnarok DG-4: Once all three parts are charged, take them to the workbench in the Canals district to assemble your specialist weapon.
Building the Shield: A standard shield is not enough; you need the upgraded Arnie shield. The shield parts are found in three locations: the waterfront, the footlight, and the canals. Build it at the workbench in the junction. To upgrade it to the “Arnies” version, you need to find three blue fuses and place them in specific locations to summon a Margwa. Killing the Margwa near the shield table will upgrade it, giving you tactical grenades that distract zombies.
The Main Easter Egg Quest: A Step-by-Step Breakdown
This is the core of the challenge. The steps are sequential and must be completed in order. Precision and speed are key.
Step 1: The Flag Rituals (Keeper Protector)
- Objective: Use your upgraded sword in each of the four districts to summon a Keeper and protect a flag from zombies.
- Solo Strategy: This is a major bottleneck. You must plant the flag and kill all zombies that attempt to destroy it. Use the Apothicon Servant and traps. The Civil Protector can be called to help defend a flag. Each ritual has a time limit, and failing means you must restart it. Expect to use your Ragnarok DG-4’s gravity spikes for emergency crowd control.
Step 2: The Train Tracks and the Wisps
- Objective: After completing the fourth flag ritual, a symbol will appear on the train map in the Undercroft. You must ride the train and shoot a specific number of wisps (floating orbs) that appear outside the windows within a short time frame. The number and order change each game.
- Solo Strategy: This requires memorization and a fast trigger finger. Use a weapon with a high fire rate, like the Vesper or a packed wall gun. You typically have only one chance per round, so if you miss, you must wait for the next train ride. The sequence is usually between 3-5 wisps. A common sequence is 3-2-4.
| Wisp Sequence Example | Location to Shoot |
|---|---|
| First Wisp | Right after leaving the station, on the left side near a bridge. |
| Second Wisp | In a dark tunnel section on the right side. |
| Third Wisp | Just before arriving at the next station, on the left near a building. |
Step 3: The Boss Fight: The Shadowman
- Objective: After the wisp step, you’ll be transported to a boss fight arena to face the Shadowman.
- Phase 1: The Shadowman floats around, summoning zombies and Margwas. Your goal is to damage him enough to progress. Use your packed Wonder Weapon (like the upgraded Apothicon Servant, the “Little Arnies”) and your Ragnarok DG-4. The gravity spikes are extremely effective against him.
- Phase 2: After taking enough damage, the Shadowman will disappear, and you’ll need to survive several waves of enemies, including a constant stream of zombies and special enemies like the Margwa. This is a pure survival test. Use the “Near Death Experience” GobbleGum here if you have it; it makes this phase trivial as you can get revived infinitely.
- Phase 3: The final phase involves using the Ragnarok DG-4 to trap the Shadowman. Place the gravity spikes on specific glowing symbols on the ground. Once trapped, unload all your firepower into him to defeat him.
Weapon and Perk Recommendations for the Finale
Your loadout going into the boss fight will determine your success. Do not go in unprepared.
Weapons:
- Primary: Pack-a-Punched Apothicon Servant (for crowd control) or a Pack-a-Punched Haymaker 12/ Brecci (for raw damage against the Shadowman).
- Secondary: Pack-a-Punched starting pistol (MR6 becomes a burst-fire weapon) or a packed wall weapon like the KRM-262.
- Specialist: Ragnarok DG-4 (fully charged).
Perks: You ideally want all perks via a Perkaholic, but if not, these are mandatory:
- Juggernog: Non-negotiable.
- Quick Revive: Gives you an extra self-revive in solo.
- Stamin-Up: Essential for kiting zombies during the boss fight.
- Double Tap Root Beer II: Doubles your damage output.
- Widow’s Wine: Provides an extra layer of protection by slowing zombies.
Completing the solo Easter egg in Call of Duty BO7 is one of the most difficult but rewarding challenges in zombies history. It requires meticulous planning, perfect execution, and a little bit of luck. The key is to practice each segment until it becomes second nature. Manage your points wisely, use your GobbleGums strategically, and don’t be discouraged by failure. Every failed attempt is a lesson that gets you closer to that final, epic cutscene.
