Portal Remastered is a mod that attempts to remaster the original portal in the portal 2 engine. The models, textures and lighting have all been updated to be more in line with the style of portal 2 while making sure the levels still retain somewhat of a Portal 1 vibe.
Major Update to Portal Remastered (includes Escape part 1 and bug fixes for previous levels)
Version 0.2 adds test chamber 18 along with lighting improvements on some levels.
