Special Dead(2006)

Overview:

When a zombie plague infects a camp for the mentally handicapped, a ragtag band of campers and counselors struggles to survive the night. The unlikely heroes fight their way off the mountain as, one by one, they're picked off and join the ranks of the walking dead. It's a campy stampede of blood, boobs and gore as some "very special" people show that they can kick some serious undead ass.
