A collection of maps made to replicate the levels demonstrated in the trailers for Portal 2, include Aerial Faith Plates, Thermal Discouragement Beams, Excusion Funnels, and Repulsion Gel. Those maps never made it into the final game, whether completely (faith plate 1) or partially (beams, funnel, and bounce gel). By "remake", I mean replicated as humanly possible due to limitations to the Perpetual Testing Initiative map-maker. Enjoy!
