Another anti-zombie traps ideas

[MrTrololo]

as we all now in current build zombies after they jump over the lower fence they falling on their faces on the ground then they stand up and i see another opportunity here-stake trap-its simple we can put stakes on ground along of fence,when they jump over fence then they would just fall and impale on stakes(only one zombie can be impaled on one quarter of stake trap what means another zombies would be able to easily walk on corpse,unless corpse is removed) and similar trap-excavacated hole with stakes on bottom and covered with branches twigs and leafs,both zombies and players can fall down and die.

zeds would just walk around uncovered holes

and third non-lethal one-just ordinary line low above ground tied and expanded between two objects that can make zeds and unaware players stumble and slow them down in consequence
