The newest game in the Call of Duty franchise, Black Ops Cold War, takes players back to the 1980s as they work to stop a Soviet attack on the Western world on both sides of the iron curtain. With the campaign comes several plotlines that Treyarch has hinted at for past or future entries.

From references to Easter eggs to other nods, these plotlines might have gone over the heads of most. But players with a keen eye were able to spot these hidden plotlines that most might have missed. Spoilers warning for Cold War’s campaign ahead.

10 Adler In Multiplayer

Since the 2019 edition of Modern Warfare, the series’ multiplayer has served as a part two to each game’s respective campaign and Cold War is no different. Set two years after Cold War’s campaign, a variety of operators of NATO and the Warsaw Pact with one of those operators being one Russell Adler.

In an epilogue scene in the campaign, Adler betrays Bell fearing the latter might turn against with the scene ending as both seemingly shoot each other. Adler being in the multiplayer shows he has survived to fight another day.

9 Perseus Will Return

The main antagonist in the campaign is a Soviet known only as Perseus who tries to use American made nukes in Western Europe in order to frame the U.S for it to tilt the Cold War in the Soviet’s favor.

Though the plan is stopped, Perseus is still out there. He makes his return in the multiplayer’s opening scene but it remains to be seen what he is planning now.

8 The CIA And MI6 Working Together

The United States and United Kingdom have always been close allies but the CIA operatives in the Black Ops series have always worked alone. That changes with the introduction of MI6 agent Helen Park into the game.

Her presence alongside Adler’s team goes to show that the U.K is worried about the Soviets as much as the Americans are. The slideshow discussing Park’s fate at the end also shows how the British are willing to help the U.S further in the Cold War.

7 Park Is An Operative In Multiplayer But Not Lazar

In the closing moments of the End of The Line mission, main protagonist Bell has to make a tough decision in rescuing either Park or another character named Lazar. Though they can choose either one of them, Park is in the game’s multiplayer, regardless of if she was left behind, whereas Lazar is not.

This seemingly hints that the canonical choice was that Bell chose to save Park since the multiplayer is set two years later, as previously stated. This ensures that we could see Park in a future installment.

6 Qasim As A CIA Agent

The opening mission sees Mason, Woods and Adler chase Qasim across several rooftops in Amsterdam. Eventually they catch up to him and Mason has the choice of either capturing or killing him.

If he is captured, the game’s ending states he was persuaded into helping the CIA in exchange for his protection. One of these assignments for him is in Afghanistan which hints as to why Mason and Woods are there in the Black Ops 2 mission, Old Wounds.

5 Imran Zakhaev’s Presence

The introduction of Warzone  has altered the course Activision will take with Call of Duty for years to come. A hint at this future is the fact that Imran Zakhaev, a Modern Warfare character, is featured in the mission Desperate Measures.

Both Modern Warfare and Black Ops have been on separate timelines from one another. Zakhaev’s presence in the game shows that last year’s Modern Warfare is connected to Black Ops and now several new possibilities for the series have opened up.

4 Nova 6 Vials In Kravchenko’s Locker

The Desperate Measures mission also includes the return of Lev Kravchenko, one of the main villains of Black Ops 1. On the bottom floor lies his office with a computer on his desk with several files on both past and current events.

One of those files is on Nova 6, a chemical in Black Ops 1 that him and that game’s main antagonist Dragovich tried to unleash on the U.S but was thwarted by Mason and Hudson. The file states that Kravchenko has vials of the chemical in his locker and opening it will reveal the vials. This shows that the chemical is not gone completely and why it all of a sudden turns up again in Black Ops 3.

3 Mason Is Not Fully Healed

In Black Ops 1, Mason was captured by Dragovich who attempted to brain wash him into a Soviet sleeper agent by using a series of red numbers. It was thwarted by Viktor Reznov who instead used their methods to make Mason his instrument of revenge on Dragovich’s inner circle.

In the Echoes of a Cold War mission, Mason and Woods return to the Yamantau facility where the WMD mission in Black Ops 1 was set. In the latter mission, players controlled Hudson who had a crossbow. Bodies of soldiers killed by these crossbows can be seen in the Echoes mission where interacting with them will show the numbers again. Showing that Mason still has scars from his experience.

2 Both Sides Think They Are Right

In the game both Ronald Reagan and Mikhail Gorbachav, presidents of the U.S and Soviet Union respectively, both are willingly to do whatever it takes to make sure their way of life is protected.

The game shows a bit of what is on the Soviet side of things and they do not seem so different than the U.S in terms of their motivations. They both feel the other threatens their respective nation’s very existence and want to keep it around forever. At the end of the day, both sides had more in common than they thought possible.

1 The Cover Foreshadows The Game’s Twist

The game’s main plot twist is that main character Bell was originally a Soviet agent working for Perseus. They are betrayed by Arash Kadivar who guns him down out of jealousy but Bell survives and is later found by Adler. Bell is then brainwashed into believing he is a partner to Adler by Adler himself and Park in order to find out what Perseus is planning.

The cover though seems to foreshadow this twist in a way that floats over the heads of most. The shows a person whose left side shows a Soviet, who could be considered to be Bell as a Soviet. While the person’s right side is an American, showcasing Bell’s new and current life as an American, Englishman or ex-KGB and operative for the CIA.
