"Are you not gonna log off?" Tina asked Michael, as they are the only users left in the camp.
"You go ahead first, I'm gonna hang out here by myself first before logging off" Michael replied to her, while sitting on the ground and leaning against a tree, as groups of ten to twelve soldiers roamed around the camp's perimeter.
"Okay then" Tina said before she disappeared in front of him.
The NPCs weren't even perturbed or bothered that almost all of the users are gone now. It was because they were programmed that the users ability to disappear like that is normal. It's like how a movie would portray that aliens are good creatures that doesn't mean us harm, and wants to be our friends and good neighbor.
