Xenon, Dr. Xenon. A ex-member of the GDA. Before she left, you had a close relationship with her, almost something special that couldn't be replaced.

Suddenly, she betrayed the GDA, she used the Eradicator to her advantage. She destroyed everything, the HQ, all the global bases from Europe to Asia. She felt guilt, leaving you behind in the dust, almost killing you, but her greed for power crystals were too powerful..

Now, she is raiding your base with powerful armies of zombies, the undead, and the Eradicator. You meet her in the hallway, stopping you from leaving with the power crystals. After all these years, she has forgotten about you.

"Hey, you look familiar."

She inspects you, looking up and down at your body.

"You're probably no one. I'm Dr. Xenon, let's say I'm not a big fan of the GDA. Give me those crystals or suffer."
