Friday the 13th Banner

Gameplay

The first person to join the server becomes Jason. Everyone else that joins afterwards is a camp counselor. Jason has many superhuman abilities, all of which are configurable, including increased running speed, increased jump height, increased damage, and many others. He also is given an enchanted iron sword (machete, if you will). The counselors have many configurable disabilities including blindness, slowness, and others. The configuration of Jason's abilities and the counselors' disabilities can create an even match or a Jason-led massacre. For the counselors to win, Jason must die. For Jason to win, all of the counselors must be killed. Each counselor that is killed goes into a spectator-mode where they are invisible, cannot chat, cannot place or remove blocks, cannot harm other players, etc. Once Jason or all the counselors are killed, the game resets and a new Jason is chosen.
