Easter Eggs

The Decimator Shield cannot be Pack-a-Punched and is only available via the following quest:

Open Merchant Road by completing a Portal Objective.
Walk up to where the Decimator Shield is being held in Merchant Road to start a conversation with the Shield. Note: You can start a Portal Objective as soon as the conversation starts if you don't want to listen to it.
Open East Spring by completing a Portal Objective.
Interact with the rune stone near Demonic Frenzy (Speed Cola) in the Tents area of East Spring.
Wait for the conversation to finish and enter the Portal that spawns behind the rune stone. Note: The conversation takes a full two minutes to finish.
Complete the Augmentor objective.
After returning to the Eastern Desert, shoot and destroy four crystals around the spawn area.
Return to the Shield to start another conversation. Note: You can start a Portal Objective as soon as the conversation starts if you don't want to listen to it.
Open West Spring by completing a Portal Objective.
Interact with the rune stone in the 'Bazaar' (Below Diabolical Damage/Deadshot) in the West Spring Area.
Wait for the conversation to finish and enter the Portal that spawns beside the rune stone. Note: This conversation takes about 1 min 30 sec.
Complete the Sacrifice objective.
After returning to the Eastern Desert, go back to the Shield and wait for it to break free and fall to the floor so you can pick it up.

Stats (Solo): Difficulty - 2/10, Est. Completion Time - 25 to 40 Mins

Obtain the Decimator Shield.
Open Debris Field by completing a Portal Objective.
Interact with the rune stone near Venomous Vigor (Quick Revive) in the Debris Field. Note: This conversation takes only about one minute to finish.
Enter the Void Portal near the rune stone.
While in the Void objective area, use the Decimator Shield's special ability (Slam) to destroy four arms attached to walls. Find them by following the energy beams from the Tome Page to each arm.
Once all four arms are destroyed, pick up the Tome Page and interact with the portal to the right of the Tome Page.
Upon returning to the Eastern Desert, you'll receive 10,000 points, various loot items, and four loot chests. The Void portal will stay unlocked for the rest of the match.

Dig four Lost Tome pages from the Dig Spots throughout the Eastern Desert.
Optional: For a free Ray Gun, keep digging until it appears from a dig spot.
Place Lost Tome pages on the Magical Barrier blocking the Deathmachine room in the Outpost Courtyard.
The Lost Tome pages must be placed in a specific order across 4 positions (Top, Bottom, Left, Right). If the first page disappears after being placed, it was in the wrong spot. Place it elsewhere. Any wrong placement resets the entire puzzle.
Once all the pages are placed, the spell will fade and the Deathmachine will become available as a reward.
If you dug up the Ray Gun before opening the room, it'll be available as a reward alongside the Deathmachine.

Dig up the radio antenna from one of the Dig Spots.
Place the antenna on the radio next to the armoured car at Merchant Road. This will spawn Boom-Schreiers.
Interact with the radio in the same room as Diabolical Damage (Deadshot) at Bazaar. This will spawn Boom-Schreiers.
Interact with the radio next to Venomous Vigor (Quick Revive). This will spawn Boom-Schreiers.
Interact with the radio inside the Market Storage (building near Deadshot). This will spawn Sturmkriegers.
When the last Sturmkrieger is killed, it will drop a chest which contains a random weapon as a reward.

Dig up the corrupted heart (purple orb) from one of the Dig Spots.
While holding the Heart, your health will be halved.
Place the corrupted heart at one of the highlighted dig spots.
Placing the Heart at one of the special dig spots rewards you with a Corrupted Heart, which can be used at the Altar of Covenants or Tome of Rituals.
You can pick the Heart back up, but there's nothing else to do with it (that we know of).

Dig up the Red Orb from one of the Dig Spots.
The Orb will fly off in a random direction; chase it down.
Shoot the orb until it falls to the ground. Interact with the Orb to collect 5000 Points.
This can be repeated by digging up other Orbs.

Similar to Origins (BO2 & BO3), there are Dig Spots around the map that contain various items like loot, weapons, etc.
