Here's something I slapped together in 5 minutes (literally!) of writing. You can submit your own; the only rule is that it must be written in exactly one contiguous 5 minute block (or 10 minutes, or 30, or what have you, but tell us how long you gave yourself).

Matt landed on the alien planet without ceremony, having tumbled from an airplane above just minutes prior. He immediately glanced around. Surrounding him was a forest of strange, bizarre flora unlike anything he had seen at home. Where was the familiarity? Where was the comfort? He had left all that behind in the dropship.

Alien calls echoed throughout the valley in which he had landed. He was a hardened soldier, but the unsettling noises still chilled his blood. He knew he had to start moving soon, or else he would be eaten by something much larger than him. It was the law of the jungle now: eat, or be eaten.

Unslinging his rifle from his back, he immediately began trekking southwest, dried branches and leaves crunching beneath his feet. He thought he could see movement at the edge of his vision. Was something stalking him? He could not be sure. All he knew was that he needed to keep moving, no matter the cost.

He spotted tracks on the ground - seven-toed tracks belonging to some reptilian thing. What strange beasts inhabited this world? And to think that EarthCom had dumped him here so unceremoniously. What was he looking for again?

Oh, that's right, he thought to himself. They suspect a Daarmid base hidden here. And it was Matt's job to go ahead and dig it up. Matt sighed. Why did he get assigned all the grunt work?

He shook his head in discontent, and marched on, leaving a fine dust in his wake.
