Realistic or Modern Heat of the Desert

[The Dark Creator]

Spoiler: TLDR/In a nutshell

A military convoy goes into a sandstorm and gets attacked within the sandstorm. Your character is the last one alive and finds that the attacker is some weird alien assassin.

A sandstorm rolls by and the escort vehicles stop. The surroundings were mostly safe, so most people took a moment to relax and refresh. You're one of the tank operators, laying down for a bit... There's gunfire outside, screams of pain. The gunfire got less frequent until it sounded like there was one shooter. There was some hellish screech, and then the last scream, quickly cut off. The sandstorm is about to pass, as your other 3 tank crew members check it out... a little too early. They also die. You hear the loud footsteps come towards the hatch... But then it jumps off. The sandstorm is gone by this time, and you have no choice but to get out and look around.
The setting starts out semi horror, but could turn a lot of directions as the story progresses. I will usually answer all questions, so please ask about anything.​
