Blade Trap

Description
The  has three spinning blades that chops players and zeds alike within a 3x3 'tile' area. It does not discriminate. It requires 20W of electricity to operate.

As of A18, you must have advanced engineering 3 in onset to craft these (unless you find a schematic).

Depending on the positioning of the blade will result in different outcomes. Placing the blade on the ground will chop of zombie legs; thus the zombies will become crawlers. On a 2 block high ceiling, the blade will chop off heads, resulting in an instant kill. Placing on a wall vertically is not recommended since zombies can hit it without taking damage but it can kill zombies most of the time.
