A disaster happen

Abrellum Corp had many bases and labs around the world. You work in the base of Noorac City.

That day, you went to work like everyday. When you're drinking a cup of coffee, an alarmed bell suddenly rang loudly.

A female co-worker asked you: "What happened?"

"Maybe there's a fire somewhere..."

Suddenly, the room was filled by white smoke. Your consciousness faded...

"Hey, there's someone here!"

"This man is still alive!"

"Wake up!"

Your eyes opened. The first thing you saw was a bunch of gas-masked guy gathered around. From their gun and uniform, you knew they were mercenaries.

A man who supposed to be the leader asked you: "Do you know what happened here?"

"I... I don't know... I don't remember."

A woman pointed a flashlight to your eyes, then said: "He's suffering a short-term amnesia. We should move while waiting him to regain his memories."
