Piston: Difference between revisions

A '''piston''' is a device that the [[Forerunners]], or perhaps the machines they left behind, installed within facilities like the [[Sentinel Wall]] as "doors" to get from level to level within the multi-tiered construct. The pistons have sensitive control-strips that open the piston when fired open or switched. The piston then splits in two, and allows the [[Sentinels]] and [[Constructors]] to move to the lower or to the higher level they desire. The openings are fairly large, however, and they allow larger creatures, such as [[Elites]] and even [[Hunters]], to move through. However, the shafts pistons guard are almost always vertical, so moving up through them is impossible without a thruster of some kind.
