This reminds me of “Mutant Chronicles” a bit.
In the year 2707, war rages between earths four giant corporations as they battle over the planet’s dwindling resources. In an era marked by warfare and social regression, the earth is on the verge of ruin, destruction is everywhere; battles explode on every ravaged continent. Amidst heavy combat, an errant shell shatters an ancient buried seal releasing a horrific mutant army from its eternal prison deep within the earth. As the mutant scourge threatens human extinction, a single squad of soldiers descends into the earth to fulfill the ages-old prophesy of the MUTANT CHRONICLES and save mankind.
