Farah, Alex, Hadir, and his team hunkered down in the ruins of the destroyed city, constructed a sort of defensive tower. They waited for the Wolf.

But instead of Wolf, Barkov's people appeared. They fought off the enemies who came later well, but at one point their numbers became too great. Hadir suddenly screamed, cutting through the loud sounds of war.

Hadir: "Alex!!! Follow me, I have a powerful weapon in my truck!"

Alex, picking up the sniper rifle Hadir made, follows him across the battlefield.

Hadir: "Open the back, I'll cover your back."

When Alex opens the back, he discovers several canisters of poison gas. He freezes in surprise.

Alex: "Russian gas?.."

Hadir: "Yes! I'm giving them back their gas!"

He pushes the truck and the canisters explode. Green gas slowly spreads across the abandoned city, killing Russians.

Farah: "Hadir!! What the hell are you doing?!"

Hadir: "Giving them a taste of their own medicine!"

The three of them ran, but Alex started coughing and fell. He drifted in and out of consciousness. Alex noticed Hadir dragging him.

Hadir carried them away from the enemies and fitted them with respirators with eye protection.

Farah tried to hit her brother but fell to the floor.

Hadir: "Sister? Sister!!"

He sighs.

Hadir: "Tell her I did it to protect her... Tell her, Alex..."

Then he leaves. Despite their masks, Farah and Alex have already inhaled enough of the gas to pass out.

Hadir is a traitor...
