Superhero Movie News claim to have obtained the script for the film and have released the "opening sequence" of the film.
The story follows Navy Seal Tyler Colt and his mission in the Iraqi desert to find a group of terrorists hiding out in a bunker. To him and his teams surprise the terrorists within the bunker turn out be nothing more then some grave robbers who have all magically died. Upon entering the bunker Tyler and his team also succumb to some mystical forces out of their control. They soon realize the bunker they have infiltrated is actually a centuries old tomb. Mayhem erupts as all the Navy seal members start turning on one another and are captivated by the forces within the tomb. Tyler is the only one to make it all the way deep within the tomb alive to find an Black Iron Sarcophagus. It's marked with Egyptian symbols like the Ankh and Eye of Horus. Here Tyler is entranced by the forces to open up and release what is inside. But after placing his hand onto the sarcophagus he is immediately stabbed in the palm with a star shaped symbol. From then on his mind is cursed with visions of Ashurbanipal, King of Assyria.....The Mummy.
I honestly have no clue how true this is but even if it's true we all know scripts change
