Ignore Amir, scan the desert again
From Create Your Own Story
There was no way the sniper could be by the mountains, you tell yourself. You decide to scan over some more of the sand-dunes, despite nothing suggesting the sniper was lying there. Another distant gunshot rang out, and Amir looked at the next victim. One of your comrades took a bullet in the stomach, and collapsed to the ground, screaming. Another freedom fighter rushed to the wounded ones aid, and Amir recognized that the enemy sniper was using a trick to lure out another target.
"Quick, he's going to shoot again! Look at the mountains!" You curse under your breath. There is no reason to look at the mountains, there's no places to hide there.
