Gordon Freeman's Day Out. A Half-Life/Pokemon Crossover
Chapter 1 The Beginning
One day Gordon Freeman was at home. This one day was before the Renaissance Cascade in Half Life which brought many talented alien artists into the world, but after the part where he put on his H.E.V. suit. He was awaiting delivery of a package from his son, Barney who lived across the road, which was being delivered by FedEx and it was that beer he owed him.
But breaking the calmness was a sound that sounded like a bang. It was a bang. Gordon Freeman knew that it wasn't the beer that his son Barney owed him because a parcel that contained beer sent by FedEx would creating a shattering noise if it had enough kinetic force to make that bang as the glass containing the beer would smash, and that FedEx always handles its packages carefully. Both of these are simple physics and Gordon Freeman had more physics knowledge than a simple physicist so he would definitely know that it couldn't possibly be the FedEx delivered beer that his son Barney owed him that made the bang sounding noise that was a bang noise.
He went to open the door and find out what the bang noise was, but it was impossible to find out what the bang noise was as there was no door to open first as it had disappeared. Instead he just went to find out what the bang noise was and Gordon Freeman found the most shocking and disturbing revelation ever. It was the FedEx delivered beer.
But a more pleasant revelation flooded in a few moments later, it turned out that it was not FedEx's fault that the FedEx delivered beer smashed apart but a strange creature's fault. Gordon Freeman used his knowledge of the physics of forensics to discover the chain of events that made it the strange creature's fault, and here it is in concise list form; the strange creature stopped the FedEx delivery man doing much, such as not dropping the parcel of beer that Barney owed Gordon Freeman, but still allowed him to die from the severe loss of blood caused by a rather nasty attack, and when this happened sequentially the FedEx delivered beer made the bang noise as it hit the floor.
