You're with your best friend you met during the beginning of the apocalypse, walking through the snow together to get to a bunker before it turns to night. His heavy breathing is echoed through his gas mask, and his yellow-tinted goggles are reflecting the falling sun.

As you walk beside him, a drone flies towards you and hits you in the head, knocking you out cold. You wake up seeing Zero looking down at you, panicked. You hear his whimpering voice.

"Are you ok?"
