Dreams.

It turned out that humanity had another planet, and an alien invasion was approaching it. I came to this planet, partly for fun and partly for extra benefits on Earth, and volunteered to join the defense forces. However, I didn't want to fight or train, so during drills, I avoided them by flying back to Earth, and on the days when I had to go to the factory, I teleported to the planet.

Then, the aliens finally invaded. The people hid in a bunker, but a small group of human traitors opened the entrance to the bunker and disabled all the defense systems. We couldn't kill them because they wore armor that was impervious to human weapons, and they targeted all of us. But I happened to have a weapon that could penetrate their armor, and I shot them all down.

In the end, the aliens went all-in and forced us into a final battle, during which they destroyed almost all of humanity. However, the last, most powerful wave of their units clashed with our remaining defenders. Due to poor positioning, the alien troops resembled huge boars, blindly charging uphill in a horde, trying to bulldoze everything with their snouts, while we bombarded them with explosives. In the end, only about five to ten people remained on the entire planet, and the rest of the surface was littered with corpses from both sides.
