Left 4 Dead 2 - Last Man On Earth - No Damage, No Restarts, Hard Rain (Expert)

LAST MAN ON EARTH MUTATION - You will play by yourself without Survivor Bots to back you up. Only Special Infected will spawn. If you get incapacitated from a Special Infected which grabbed you, you will automatically revive yourself, but your vision will be black and white, which means if you do not heal, you will be killed if you go down again. To balance this out, the Director orders the Special Infected to run away briefly after incapacitation, allowing you time to recover. Defibrillators do not spawn in this mutation as there are no teammates to resurrect. There are also very few pipe bombs and no Boomers due to lacking Common Infected spawning in the campaign (though the Church Guy can still become a Boomer). Health kits spawn much more frequently than usual to help the player, especially on harder difficulties.
