Killzone

The Killzone of a area, refers to a restricted area's inner box that designates its area of lethality, the killzone is always inside of the restricted area. There is one exception, the killzone of The 121k Armageddon is orders of magnitude larger then the restricted area due to the qualities of the Perpetual-Orbit-Falldown.

In more practical and more common instances, the Killzone can refer to the area contaminated by Cacti Bosses, or the site of a massive TNT-Bomb.
