The Bridge of Hades in God of War.
The Bridge of Hades was found at the end of the Path of Hades.
It was a long straightforward "bridge" that consisted of nearly a dozen small and round pillars. On the platform before the bridge, Kratos killed about a dozen Satyrs in order to raise the pillars. A rope that lead topside was suspended at the end of the pillars, which allowed Kratos to climb out of the Underworld.
