The Modern warfare series has delivered some of the most intense and cinematic storylines in Call Of Duty history. With its mix of military realism, deep characters, and high-stakes conflicts, the franchise has built a gripping narrative that spans multiple games.

However, despite the detailed storytelling, there are still several major unanswered questions in the Modern Warfare universe. As rumors about Modern Warfare 4 (Call of Duty 2026) continue to surface, many fans are wondering if the next installment will finally solve these mysteries. Here are the five biggest unresolved plotlines in the Modern Warfare timeline.

What Really Happened to Khaled Al-Asad?

One of the most enigmatic figures in the Modern Warfare reboot is Khaled Al-Asad, the leader of Al-Qatala. In the original Call of Duty 4: Modern Warfare, he was a secondary villain who was quickly eliminated by Captain Price. However, in the 2019 reboot, his role became much more complex.

After the death of The Wolf (Omar Sulaman) and the imprisonment of Hadir Karim, Al-Asad emerged as the new leader of Al-Qatala, working alongside Victor Zakhaev. But his story took an unexpected turn—Zakhaev put him on a train and sent him away, never to be seen again.

What happened to him?

Is he still leading Al-Qatala in hiding?
Was he removed from power by Zakhaev?
Could he return in Modern Warfare 4 as a major villain?

With Hadir Karim’s fate seemingly sealed in Modern Warfare 2, the true identity and whereabouts of Khaled Al-Asad remain a mystery.

What Happened in Beirut?

Beirut has been mysteriously referenced multiple times throughout the Modern Warfare series.

In Call of Duty 4, Captain Price and General Shepherd mention an operation in Beirut.
In Modern Warfare 2019, Beirut is referenced again during a conversation between Price and Farah Karim at the end of the campaign.

Despite these hints, we still don’t know what happened there. Given how important it seems to be to both Price and Farah, it’s possible that Modern Warfare 4 could finally reveal this missing piece of their past.

What Was Makarov’s True Plan?

Vladimir Makarov, one of Call of Duty’s most iconic villains, returned in Modern Warfare 3 (2023), but his true motivations remained unclear.

What we do know:

Makarov’s father was a high-ranking Soviet official who took his own life after the collapse of the Soviet Union.
This event fueled Makarov’s hatred for Russia, leading him to join Roman Barkov’s forces.
He launched an invasion of Urzikstan, but his true objective was never fully explained.

Modern Warfare 3 cut several missions that were rumored to show Makarov’s backstory and his connection to Barkov. If these details had been included, his character would have been far more compelling. Will Modern Warfare 4 explore his past in more depth?

The Mexico Storyline: What Happened to Valeria & Alejandro?

Modern Warfare 2 (2022) introduced one of the franchise’s best side stories—the battle between Los Vaqueros and the Las Almas Cartel. This conflict was central to the game’s Mexico-based missions, but it never received a proper conclusion.

What we know:

Alejandro Vargas (leader of Los Vaqueros) was captured but later rescued.
Valeria Garza (leader of Las Almas) was imprisoned but ultimately released.
A Warzone season focused on their continued conflict, yet the storyline was never resolved.

There were also rumors of a Las Almas Warzone map and an expansion campaign set in Mexico, but neither materialized. Is this story arc abandoned, or will Modern Warfare 4 bring closure to the fate of Alejandro and Valeria?

The Mystery of Alex Keller

Alex Keller remains one of the biggest unsolved mysteries in the Modern Warfare reboot.

In Modern Warfare 2019, he was a CIA operative who assisted Farah Karim and the Urzikstan Liberation Force.
He seemingly sacrificed himself to destroy Barkov’s gas factory, yet later appeared in Warzone, missing a leg but very much alive.
In Modern Warfare 2, he was completely missing from the main campaign.

Then, in the Modern Warfare 2 raid missions, it was revealed that his full name is Alex Keller—but we still know nothing about his past. Who is he really? Why does he only go by Alex? What happened to him after his Warzone reappearance?

Will Modern Warfare 4 Answer These Questions?

With Modern Warfare 4 rumored to release in 2026, there’s a chance that some of these major unanswered questions will finally be addressed. Some of the biggest possibilities include:

The return of Khaled Al-Asad as a major antagonist.
A flashback mission revealing what happened in Beirut.
A deeper look at Makarov’s past and his true endgame.
The continuation of the Mexico storyline featuring Alejandro and Valeria.
More information on Alex Keller’s true identity and origins.

Call of Duty’s Modern Warfare saga is one of the most complex and engaging storylines in gaming, but these loose ends have left fans wanting more. Will the next game finally deliver the answers players have been waiting for?
