It was a dying world. The system's sun was getting ever closer to its giant phase. The Earth's ozone layer had given up trying to protect Earth from the radiation. Most of the planet was a giant, radioactive wasteland. This is where the two humans landed. As soon as they got there, they obviously thought about where they were, because as far as they knew, they could have been on Mars or some alternate dimension that only came into being yesterday. Then they realized that the air was slightly toxic and that the planet seemed to be actively trying to kill them.
The only thing in the area worth mentioning, the outpost, was about half a mile from the small crater generated when the humans landed. The victims, hoping for rescue, noticed that the abandoned-looking outpost had started to open its doors. They almost cheered, because this was the first time they had felt hope since they saw the nuke, whose explosion had accidentally sent them into the future in the first place. But that little bit of hope faded instantly when they saw what was coming out of the doors. There was smoke, which did nothing but further intoxicate the air. There were lasers, which was rather unsettling. But most unsettlingly of all, there were robots coming out of the doors. Human-like robots that could disguise as one if they weren't so bulky. And there was an army of them.
They were all armed with laser guns. The humans knew that the robots were trouble, else why would there be smoke? The humans tried to run so they could put some distance between them and the robots. The robots spotted them.
"Fire!"
