This means that all of the people who came to the Survivors aid only to turn into zombies/end up crashing and dying later could very well have been unknowingly infected by them. Nice Job Breaking It, Hero: As revealed in The Sacrifice, the Survivors are not quite immune to the Flu, but instead are Asymptomatic Carriers, meaning that the disease is still very much active and contagious by them.Then again, only on Expert does friendly fire actually do damage equivalent to a bullet. Major Injury Underreaction: Getting shot by their fellow Survivors makes them shout in pain and trade insults, but less like they got wounded by a bullet, and more like theyre being pelted with paintballs.Made of Iron: They're capable of withstanding getting crushed, shot, punted across the street, swarmed by a hail of fists, burnt by acid, and set on fire, even on Advanced difficulty.The second game in particular has this happen even more cruelly, with the mall and carnival evacuation sites overrun mere days to minutes before the group reaches them, and the civilian effort to evacuate people in the swamps overrun just before they crashed there as well. Late to the Tragedy: The majority of campaigns have the Survivors arriving at a location in hopes of rescue, only to find out that evacuation has long since passed by and the location is swarmed with infected.However, they never hesitate to come to their rescue if they're in trouble and will sincerely mourn for dead Survivors they find. Jerk with a Heart of Gold: Francis and Nick are the cynics/jerks of the teams, regularly belittling and insulting their fellow Survivors while sometimes lamenting how screwed they are.The first game's Survivors have known each other for two weeks before the events of the game take place, but the Survivors in 2 begin their journey as complete strangers before they begin to bond later on. Fire-Forged Friends: The Survivors all care deeply about each other, whether some of them like to admit it or not.When their health starts getting lower and lower, they'll slow down, walk with a limp and complain regularly about the pain, and even prepare to die out loud if they've received too much abuse. Big "NO!": They'll let one out if a Smoker ensnares them, giving them just enough time to shout in dread before the pain comes.Badass Normal: All eight of the Survivors are more or less regular people caught in an apocalypse, and they're all capable of working together to kill hundreds of thousands of zombies in a single campaign.Action Survivor: As far as the Survivors are concerned, the only thing that really matters in the end is getting out of the East Coast, no matter how many mutant zombies and obstacles stand in their way.They are all seemingly immune to the Green Flu, giving them the sole edge they need to stand a chance against the infected hordes. Grouped up together by circumstance, the Survivors are among the few survivors of the Green Flu epidemic who have been left behind by evacuation efforts, forcing them to fight their ways out of the crisis themselves.
