Luke alerted the others that they would have to cross the river and fight whatever was there once the choppers appeared, but there was no sign of them even when the night completely fell.
"What time Billy said that the attack would start?" Luke asked.
"Around 17: 30," Amanda replied.
"Did they change their minds or something happened to them?" Celia asked. "I can't see any other explanation to this."
Luke looked in the direction where the chopper came from, but he didn't find any signs of smoke or anything like it. If monsters attacked the place, they sure did it without causing a ruckus. Still, the only way for that to happen would be by a crystal appearing in the middle of the base, and the soldiers didn't have any chance to fight back. Considering that the radio transmitter didn't pick up any call, Luke couldn't tell what really happened.
