"So, what now?" Charlie asked.
Matt looked back down at his wrist device and said "Easy. We turn it off."
"Just like that? It seems ... too easy. Isn't this supposed to be a game?" Charlie asked.
"Yes, but it always starts off easy and then gets more difficult as you go. It's called a learning curve." Matt hesitantly stood up and looked left and right. When he saw that no one was around, he activated something on his "watch" and the force field disappeared. "Come on. Let's make this quick. I only disabled it for a few seconds. They'll just think it's a glitch."
The three of them sprung from their cover and ran past the edge of the spaceport. Just seconds later, the blue force field reappeared.
"Now wh ..." Charlie began, but Matt put his hand over his mouth, silencing him.
"Shh. Look," Matt whispered, pointing. Charlie looked past large metal crates and containers and saw two men carrying guns. "Security."
"They look human," Charlie whispered. "I thought ..."
"Sometimes aliens are the bad guys, sometimes they're not."
"So, now what?" Charlie whispered.
Matt looked at his "watch" and said "We need to get into that building." He pointed at a three-floor building. It wasn't too far away, but they'd have to deal with security to get there.
