Earth. Third planet from the sun. Atmosphere primarily composed of nitrogen (78%), oxygen (21%), and argon (<1%). Home to over six billion carbon-based lifeforms, species homo sapiens. Preferred vacation destination for millions of intergalactic travelers throughout the galaxy. Preferred hideout for thousands of hostile aliens on the lam.

As a member of our elite, top secret branch of the U.S. government known as the Men In Black, it is your solemn duty to protect the earth from the scum of the universe. To aid you in this directive, the agency will equip you with the most advanced nanotechnology and energy-based weapons systems on the planet. However, you must be ever vigilant in never revealing the presence of aliens to regular citizens, as that forbidden knowledge would lead them to certain insanity. Without question, this is the most difficult job in the known universe. We accept only the best of the best, and demand nothing but professional excellence from our agents.

So, do you think you have what it takes to become one of the Men In Black? Good. Let's rock!
