When that first bullet enters your back, just below your right shoulder, the first thing you think is, "Oh no." From there on out is determined by how well you keep your head (figuratively and literally) and how many more times you get hit. In my case, it was: "Oh no. Spin. Drop, drop." Then I noticed I was sitting on the ground, facing gunsmoke. "I can't believe he got me here." Though at the time I was touching the area just above my heart, I was refering to the geography. It was an astoundingly remote place to be found, much less killed. Anderson didn't bother or hazard coming in close to finish me off. I had to wait for them to reload. I thought, "Oh no," a couple more times, and mumbled "Damn it," repeatedly. I stood up long enough to take the next volley in the back. And then I was dead.
The period between hitting the forest floor and being a ghost will be, I think, the hardest part to describe.
