"Clay." Macey started. "In case we don't make it-"

"Mace don't talk like that." Clay interupted. "We can and will get out of here."

"Oh I know that look." Clay turned to her. "What's the plan Clay-man? The undead are attacking."

"We power up. We try things. If nothing works...we abandon the Fortrex." 

"Charge!" Lance cried. Every one dashed out and began fighting. Their weapons barely stunning the undead. 

"Fall back" Clay shouted at last, his bones tired and his teammates tiring. "They've taken the Fortrex."

"I know where we can go!" Macey cried. "Follow me!"
