I didn't solve 7 through 11, but I know the answer for 12. That's why I was posting; the two epilogues imply different stuff. Gonna write out some stuff using font the same as the background.

Next bit is a description of each epilogue and an explanation of my confusion, so big spoilers: The epilogue following 'went for a weapon' continues in the gas station. Jack doesn't murder Jerry and has a conversation with Benjamin about Nick Bostrum's simulation hypothesis, and the general implication seems to be that Jack accurately described his experiences, and is basically going to keep living in the simulation, generally accepting it as a new reality. The epilogue following 'went to get help' is an image of a note from 'C' and it's obvious that it's from Claire, and that the previous section was a lie; Claire and Loren actually survived, but the lie would hopefully help buy more time for them to go into hiding.
The disparity I was asking about was the gap between what the two endings imply about the actual events in 'Void'
