Rules of Delta: Starting with the Lost Dam

"It's too late, those guys are coming." "I don't know if I'll survive." "So, I've recorded everything I know. Players who get this phone must remember and follow these rules." "1. Operators who haven't evacuated must check their physical condition. If normal, please go to the administration building." "2. Go find Seid! He will protect you, and only he knows the real evacuation point!" "3. The Lost Dam has 'pseudo-humans' appearing. If you encounter them, kill them immediately!" "4. If you encounter machine gunners in the wild, escape immediately, because they won't leave their posts without permission." "5. Most importantly—" Click! Before Feng Yi could finish speaking, the phone screen froze and started making noise. The next moment, a green humanoid shadow pounced on him. The screen went black, replaced by a piercing scream.

Ye Yan fell silent. Oh no, this isn't the Delta he knows.
