I’m having the exact same issue and it started about a week ago too. Random crash, no pop up, no sound, just game closes instantly and goes to desktop. It just happened now. It was my third game of the night, and it happened right about the same time as I was about to finish eating an elite poison hound. I was hit with a tracking dart while eating it, and just as I was about to finish eating, the game closed.
I’m verifying my cache now… 2 files failed to validate and they will be reaquired. I know which files they are, they are the two video files. I renamed them so I didn’t have to watch the intro video upon starting the game. http://www.reddit.com/r/EvolveGame/comments/2vcne7/how_to_skip_the_game_intro_videos/ link to where I found out how to do this.
I think I’m going to remove the game and re-download it too, to see if that helps.
edit oh yeah, this never happens when I play solo mode. Only in multiplayer.
