The gauntlet is a challenge where you get 1 of 3 random win conditions, kill # amount of zombies, survive for # seconds, or stand in # circles. The amount of zombies is a random number from 25 to 50, the amount of seconds you need to survive is a random number between 30 and 60, the amount of circles to stand in is a random number between 3 and 5. You will be given at least 1 random weapon excluding the pistol and landmine, sometimes you will be given a second weapon which can not be a pistol. Once you have completed the objective you will be given another random weapon and another objective and the difficulty will increase. This will go on until you die. Note that this, and the game in general, are still a work in progress, things are not final and are subject to change.
