A man walks in wearing a blue suit. This man is a tall, gaunt figure. He's fairly intimidating, but still looks approachable.

He speaks. "Everyone, have a seat."
A whiteboard is in the back of the room. He pulls out a remote, and a projector projects onto the white board.
"Alright, so here's what's going on, agents. I was recently assigned a team of agents to be under my command. Each one of you was handpicked by myself from a very short list of section 1 rookies. Feel proud. Today, you'll be given your first assignment."

The projector screen emits an image of a playground. There's a few figures there. "We're going to start you off with an easy job. We've recently found a few zombies wandering about a playground at night. Kill them. Don't get caught."
