Relic Of The Undead is nuts! The idea of the game mode is that there is a special zombie head and let me tell you that this is the most important zombie head in the world. Not only do you need to grab it, you need to keep hold of it so that you can capture its soul. Of course, the enemy also want this zombie head so you have to keep running and hope that the squad is going to have our back. When you capture the soul another zombie's head appears and it is round 2.
