sentences:  Some elements supporting emergent gameplay arose during testing of the game's various systems.One of the Typhon aliens, the Mimic, was inspired by the creature of the same name from "Dungeons & Dragons", and was programmed to take the form of any object smaller than itself in the room, avoiding the use of scripted events and allowing the alien's artificial intelligence in the game's software decide what to replicate.Separately, one of the tools developed by Arkane was the psychoscope, which allows players to scan an alien and learn and then use its powers; when the programmers learned of this, they quickly found that having players be able to copy the Mimic's power created a depth of new gameplay options, such as taking the form of a small object to sneak into small places, or taking the form of a non-flammable object to roll through fire-laden areas.
