I installed and played through 4 of the 5 characters stories in 400 days today.
The problem I'm having is in Russell's section, just after arriving at the gas station. The gunman starts shooting, I dodged to the gas pumps. Nate yells to get behind the truck, which I do. He then says to have a look at where the shooter is. I look over the truck, and duck back down after the gunman shoots.
At this point, the edges of the screen go red, and it eventually makes a gunshot sound and the game over screen appears. After clicking to continue, it puts me just after I see the gunman and duck down, Nate starts talking, a gunshot is heard, and I go to the game over screen again.
The only way to get out of the loop is to hit alt-f4. On reloading the save, I end up at the same point, with Nate talking, a gunshot, and game over. I tried exiting out of steam and reloading, but that doesn't work either. I'm uninstalling/re-installing to see if that somehow fixes the problem.
Any other advise would be appreciated.
