I decided to start from scratch, so I went way out into the wild. After gathering some resources I had acquired an iron sword and armor. While mining, a flaming zombie started attacking me. Why is it that I could not defeat a friggen zombie? I tried to do some research and only found more questions. Who or what is Marlix and Momentus? Please link me to or explain flaming zombie, Marlix and Momentus. Thanks.
Basically, EMC has added some custom mobs in. Here is a thread I found, but it seems to be slightly incomplete: http://empireminecraft.com/threads/guide-the-survival-update.26553/
