"In a nutshell, Action Squad explores. This generally occurs late at night, to aid in avoiding other people, particularly those with badges and funny blue uniforms. We climb buildings, sneak into factories, crawl through all kinds of tunnels, spelunk old brewery caves, poke around abandoned buildings, and run across the rooftops."
These people go where you know you want to go, but shouldn't.
Remember, don't try this at home (or work), kids.
