"Portal Remastered" is a recreation of Valve's game from 2007, made with Unreal Engine 4. The main goal of the game is to recreate the first Portal game, without all graphical inconsistencies created by all differences between the first game and its sequel (like elevators between levels, GLaDOS appearance...).
There is a screenshot of the zone area from the first level of the game, on the 22nd of July 2017.
