Science Fiction Double Feature (Purple Haze variant)

A man finds himself walking alone in the middle of a desert with no memory of who he is or how he got there. Another man allows his DNA to be spliced together with a long-dead Martian race in order to survive on the red planet. Both are about to find themselves in a struggle for survival among the harshest conditions they could ever imagine. This is the Science Fiction Double Feature, "Purple Haze" and "The Foodies of Mars", a pair of stories offered with two variant covers.
And fans of my horror need not worry; these are science fiction stories, but there's plenty of horror between these pages as well.  In fact, you may never look at a hot day, or a plate of food, the same way again.
