HALL OF THE DEATHS
The catacombs of the Eden accommodate this hall. You will not find spiders or gargoyles there, but a swamp which slows down every person committing to it of 33 %.
A little more complex than both precedents, he(it) presents two exits(releases) in every camp, in two different floors: one made arrive at the level of swamps, the other one in height, in a corridor(lane) allowing to arrive directly at the identical exit(release) of the opposite camp. Two bridges(decks) and two oblique pieces allow to change floor.
The corridor(lane) of the height is closed by doors, opened grace to a systeme of control levers.
