Mario and Luigi were en route for the Mushroom Kingdom, unaware that there was someone else from their world that would be soon following.

A loud beep, the codec frequency blared, a mysterious voice sounded through, "Do you copy? We have had some strange reports coming in. Large pipes have appeared throughout the country. We have already isolated the majority of them."
A raspy voice responds, "Pipes? What do you mean?"
"Large pipes, big enough for people to crawl through. Strange creatures have been coming out of these. We've had reports that have claimed to see robotic animals, flying crabs, and other super natural critters. No reports of intelligence yet. Judging from the technological achievements of some of the captured escapee's, we can assume we're dealing with something far beyond our understanding.
"So I guess you want me to check it out right Colonel?"
"That's right Snake, We've isolated one of the tubes just outside New York City. We want you to head there immediately. You're to enter pipe to gather intel. This is a sneaking mission. We don't know the dangers involved. We don't want whatever is in there to know we are there too." Campbell replied.
Snake pulls out a pack of cigarettes, and throws one in his mouth, "This sounds like fun." he said while lighting it.
Campbell continues, "We've sent probes into the pipes, its breathable air, but the environment is radically different. The Codename for this mission will be "Emerald Field" Good luck."
The communication blares out.
Snake takes one last look. The jungle; He's spent the last month out here on field training, eating snakes and other animals to survive. He was looking forward to getting back to civilization, but now he's starting to look forward to his next mission.
He gets up, "Should be fun", he thinks.
