Prologue of Rareonce-Revelation of the Weavers

You wait and the general sends someone to check it out. He's pulled inside and imps start rushing out!

Your unit starts fighting for it's life and imps crawl on one of the soldiers next to you and rip his eyes, out, his caterwauling screams being smothered as the grab into his throat and start clawing, killing him and they start to eat him.

You need to fight back, what do you do?
