A man is shot with a crossbow. He gets injured and goes down to the wounded state.
In his final fading breaths he sees the man with the crossbow look him in the eyes and watches as he takes aim.
Just before he passes out, he sees a savior. An angel. A man with a AK-47 who puts a bullet right between the eyes of the man with the crossbow.
Everything fades to black. He wakes up, in a house. He’s lying on a bed with a IV hooked up to him.
The man with the AK had saved him. He picked him up, carried him to his house, and saved his life.
For that the man would forever be thankful for.
The man with the AK had made a friend.
(My idea is to at least carry/drag wounded or passed out people. This would be cool because you could drag a friend behind cover in a firefight, or make a new friend. The whole thing with the IV and the bed is just something I threw in there).
