In their first hours of playing on the server the survivors start "SURVIVIOR"
a job is randomly assigned to him with their unique StarterKIT.
Thereafter two voices open to him:

Either it sinks and becomes "BANDIT"

by tracking down "SURVIVORS" and "HEROES" and loses Karma.

Or he saves his Karma and takes the path of "HERO"

by suppressing the zombies (with bare hand or with the firearm) or by killing "BANDIT".
