Zombies in the Machine

Crimebot lay on the ground. Zombies had knocked his legs out from under him, and he had gone down hard with a loud crash. He was positively forlorn, as he figured his minutes were numbered.

But then he realised something very important as the first set of zombie teeth bit down on his leg-
He was made out of Titanium! Filled with a new energy at this realisation, Crimebot leapt upwards in a dramatic fashion and hovered in the air a moment while the farmhouse seemed to fade out behind him and be replaced with a rapidly moving single-colour background.

Landing in a jumble of confused zombies, he remembered something from the days when he was just being built, after he had gained consciousness but before he could move his body freely. He glimpsed his creator's face, and some of the many words of wisdom he had imparted on Crimebot.
"Remember," the man said, "If you're ever fighting zombies, their weak point is the head!".

Crimebot smiled slyly and shook the zombies who had climbed onto him while he was having his flashback off. Setting his lasers from "Stun" to "Kill" (The settings on his lasers were actually comically mislabeled, as they should have read "Kill" and "Kill Harder") he started firing randomly, knocking zombies over left and right. Then he realised he should probably have paid heed to his creators words, and so he started aiming his laser blasts at his enemies heads.

Heads exploded everywhere. Zombies fell one after another, then two after another, then ten after another. Soon the entire house was void of moving zombies. Ross and Max came downstairs and Max gave Ross a ridiculously over-the-top high five.

Crimebot whirred. He was happy he could protect his friends.

Suddenly, one of the corpses moved! Crimebot, not wanting his friends to get hurt, fired a missle at it from his backpack. Unfortunately, the missle went straight up into the ceiling and caused part of the building to collapse on Crimebot.

He woke up some time later, only now he was standing outside what looked like an old mind shaft with Max and Ross.
"What happened?" he blooped, "Last I remember I was in the old farmhouse!"
Ross chuckled. "Don't you remember? You put on quite a show! One might say you brought the house down!" he said, causing Max to laugh uproariously.
"Where are we?" Crimebot chimed.
"Outside the old Winslow mine," said Max. "I carried you here," he finished.

Crimebot looked up at the mineshaft entrance. It looked pretty terrifying. Spooky sounds eminated from within. No one knew what was in that mine! Though danger lurked ahead, Crimebot hovered forward a little. "Looks like I'll have to go first," he said courageously, and headed into the mine, with his two human friends in tow...
