Walking Turret

The Walking Turret, also known as the Moving or Mobile Turret, is a Sentry Turret variant cut from Portal.

Overview

 * The Walking Turret was first revealed to the public through concept art during PotatoFoolsDay ARG in 2011. Valve animator Karen Prell elaborated during Animex 2012.
 * The Walking Turret was discarded in place of a static, single-directional Sentry Turret
 * The Walking Turret was capable of a ball pose, presumably to fling itself or be flung. This position could possibly have been its idle pose, activated by the player's presence and proximity.
 * The Walking Turret's Personality Construct design was kept, and can be seen in the Rocket Turret design.
