The two decide to take a run for it, as there are too many to confront. They head off into a narrow corridor and run up the stairs. As they head up, they run into what looks like parasites or leeches. There are hundreds of them, and Kirby tries to eat them, but this is the one food that he can't stomach down, and he spits them out. Rebecca tries to give Kirby some cover, but the leeches start to form together into a human leech and it lunges out towards them. Rebecca defends herself as a stray bullet comes from behind them and makes the leechman splatter onto her and Kirby. Kirby jumps up and down joyfully that someone saved them, as Rebecca tries to recover.
Rebecca asked the man, "You're... Billy Coen, Ex-Marines officer, aren't you?"
He responds, "Well, you're right. What of it?" "You're under arrest for murdering 23 people." Responded Rebecca, but what Billy said next stunned her a little, "Princess, in the situation we're in, that doesn't matter. Besides, I didn't kill them anyways."
Rebecca looked at Kirby and said, "Then who did then?" Billy pointed back towards the undead coming towards them, as he shot them down. "And they're not alone. Our only choice to survive is to team up. So what's it going to be?"
Rebecca was hesitant at first, but she looked at Kirby, who nodded at her, and they decided to team up, for now.
The three decided that the only way to get past all these... zombies was to get off the train. Before they could do that, the train was set into motion and the trained speeded off. They painced and they had to figure out how to stop the train to get off. Along the way, the continued to fight off zombies, zombie dogs, leeches, and Rebecca's team mate Edward, now part of the undead. She had to stop him, and she took him out. They continued until they got to a certain part of the train.
They got close to the control room until a large crash was heard ontop the train. The three proceded with caution until a large scorpion came crashing through and attacked them. Kirby jumped in to distract it long enough for the others to attack it. It threw Kirby off and it went off to attack the other two. Kirby didn't have a lot of time to think. What does he do?
