This entity handles if players can damage each other depending on the zone that they are currently in.
For example we will not let players kill each other inside a city, but we allow it outside.
► Inside this system we also handle the soundtracks and display an onscreen message to
let the user know that has entered a new Zone.
► Handle what happens to the player when dying inside the zone, for example, respawn in
a new inside a safe zone.
