here’s the description of the movie:
The movie was probably made during the late 90′ early 2000 and it’s an action/horror film.
The movie is about a group of soldiers (futurist black colour full body potection equipped) that are being sent to a village in the middle of a desert during a sand storm, when they arrived they dind’t found anyone, but when the night settle down a group of “monsters” that looks like human arrived and the two group started fighting eachother, if i remember correctly the soldiers had laser (maybe?) guns, while the monsters had strange weapons all hand made (medieval looking swords and some ninja looking weapons).
