I have found that if you place killballs on the other side of an object such as a wall or block, all the orange energy on the opposite side of the center of the ball will be harmless. You can walk inside of killballs. The effect is a very blinding effect. Ex. Build a line of tubes Place a killball on the tubes Walk in side the tubes Great to manipulate Lines of Sight.
Yes, and whats more I can explain why. It is because the kill ball radiates out death but it can't go through objects like bubble shields and pretty much everything else. But it is quite cool, because you can have one 'blocking' a tunnel but it really isn't!
I can imagine an infection map centered around a circular human area, and multiple tubes leading towards that area and are "blocked" by kill balls, and a zombie surprise attacks the humans through one of the many tubes. Their only defense would be fire blindly into the tubes.
That's strange. I once blocked off the tunnel inside the crypt by geomerging a killball into the tunnel into the crypt. Then everyone got stuck.
Here are the pictures I took a shortcut when I embedded them thats why they're small, but you can still see them.
