Kill Ball

Killballs are a large, spherical, orange-colored objects that can be placed in Sandbox by Forge. There are four available for use. It was originally thought by Bungie to be two, but has since been rectified to four. Once spawned, they become static objects that kills everything on contact.

Function
Despite the generic title and description, the Killball does not simply kill everything it touches, or everything that touches it rather as the Killball rarely moves. These descriptions are not completely false as the Killball kills almost everything it comes in contact with. These things include players, vehicles and most equipment. The brief moment of invincibility as an overshield charges up also fails to withstand the Killball.

Exceptions
In general, all weapons can be safely fired through the Killball with no need to worry about adverse effects. Testing in particular on Human projectile and Covenant energy weapons has shown no effects on the projectiles. Brute Shots and Needlers also work fine through the Killball. Fuel Rod Cannons also work fine as does the Flamethrower.

The weapons that do not work are the Rocket Launcher and Missile Pod as well as all grenades. All of these weapons however can be fired into the Killball and be expected to work. It is only when they attempt to leave the radius of the sphere are they destroyed with the effects that one would expect if they hit something. For example, rockets will explode with splash damage onto the other side.

Bubble Shield
Perhaps the most interesting property of the Killball is it's inability to effect a Bubble Shield's functionality. While all other equipment explode on impact, the bubble shield can safely enter the Killball and will be deployed. The bubble also negates the effects of the Killball and so it is possible to stand inside the Killball so long as there is a bubble shield active. This effect can be used to reach the 'core' of the Killball which is in fact, a solid object.

Safe Zone
The Killball's properties do not end with functional Bubble Shields and premature detonations, but also include a "safe zone" in the Killball. When spawned, there is a region within the Killball that will not kill objects as they come into contact on the very top of the Killball. If the Killball is placed above the ground by a few inches, the optimum height is a block and two double walls laid flat. This apparently safe region of the Killball is a movable object and will spin along with the rest of the ball.
