Spike

The spike is a hazardous object found in Hexen.

It is a massive pillar of tan stone sharpened to a point at the top, which may be in a raised or lowered position. When lowered, the only hint of its presence is some disturbed soil around its location. Scripts can trigger the spikes to raise or lower according to the level designer's desires. If a player or monster is standing over the spike when it begins to rise, they will be instantly and brutally killed, entering their gib state if they have one. If a spike makes a kill, bloodstains remain on the pointed end.
