One fun thing in #LucasArts' #IndianaJones and the #InfernalMachine is this area early in Nub's Tomb, where Indy descends a staircase with twin sets of treads flanking a flat central section.

It's likely a homage to the stairs in the Krell ruins in #ForbiddenPlanet, which were designed by the filmmakers to suggest the Krell had tails and crafted their staircases accordingly so as not to bump their tails on the steps!
