Portal: Unity is a mod for the Valve game "portal" with almost everything revamped. New story levels, New textures, redesigned portals, new protagonist, new antagonist and much more. !!PLEASE NOTE!!: You need to download the steampipe patch for it to work with the new SteamPipe system steam uses. To download this just go to the 'Downloads' section on the moddb page. (It's also recommended that you download the lazer fix patch as that fixes a critical end game bug) Instructions on how to install the patches are included with the corresponding patch.

This is a really cool mod, but for me (and by 'me' I mean no one else has this issue) the portals are kind of glitchy, i.e. they are just clear rectangles with a large orange/blue colored oval on the inside of it. Not only that, the boss fight (I have no idea what 'boss' I was actually fighting, so I don't know if I should even call it a 'boss') was very confusing; I didn't have a clue what I was supposed to do. Other than all of that bull-crap, this is an epic mod! 9/10
