Its when someone gets devoured by the wall of death.Everybody else fails the mission and you have to restart again. At first it wasn't too bad.But then it got annoying as hell especially when your halfway finishing the stage,then someone ends up getting swallowed by the wall with many evil faces.Hell I hate when I get devoured because I ruined the game for everybody else. I know the developers did that too add tension,but I wish they had an option to turn it off.The game mode itself is a cool feature,but I can't stand when I lose a game when someone else fails.What about you guys who played the game mode,whats your thoughts about it ? 
 
(For people that don't know.Fucking run mode is when a 4 man squad.Has to out run this giant evil cloud with faces while fighting off enemy soldiers)

Haven't played Fear 3 but most multiplayer mode in games rely on everyone making it. Even playing team death match games you can still lose badly if someone on your team is just shit. Is the dificulty low enough that you could still make it with only 3 or less players? Seem odd that they wouldn't let you continue with 3 player tho. At least stuff liek Left 4 Dead, Horde or Nazi Zombies lets you keep going even if you stand zero chance on your own.

But it's the whole point of the mode. It is the mode.

That's like wanting to switch-off death in deathmatch.

There is host migration in fear 3.People do tend to quit in fucking mode,if they're the one responsible of ruining the match.

Yeah, it sucks. I want to love the mode, but everytime I play, one guy doesn't know where he is going, and gets devoured by the wall.

I usually do fucking run mode on solo practice first.To make sure I know where I'm going and what to expect.Even though I had some practice with fucking run mode I still haven't beaten a level yet. 
 
Edit: Well I beat 1 level called street cleaning  on fucking run mode on solo practice.I played it on easy to see the whole stage and enemies. Even though I had it on easy it was still pretty tough to get pass.I can't even begin to think of putting the difficulty on insane. It will be so much misery.
