Play Portal:TFV in First Person. I did NOT create much of this, this is mostly just the PortalTFV Mappack from wecreatestuff.com, i only did the "mod" part of it.

Putting aside the way in which this mod has appeared on moddb, I am going to review the mod itself.
For anyone who was a little upset at the short play time involved in Portal, this mod is perfect. A 3D replication of a mini-flash game version of Valves triumphant puzzler it fleshes out the chambers and adds a whole slew of new problems for you to solve.
There is little by way of over-arching plot in this mod, in fact there is no plot whatsoever, but where that fails the sheer number of levels (40+ at my count) make it a valid addition to anyone's portal experience.
Guiding you through from the very basic to the frustratingly taxing it almost seems like portals cutting room floor has been collected and pieced together to give fans an psudeo-directors cut, a sort of Portal: Extended addition.
There is little more to say in regard to style, character or original content, the mod uses Portals textures and elements exclusively (with teh addition of the dropped 'fizzler') and even the various comments from GLaDOS. Its originality is only found in the varying and fun-to-play test chambers which will no doubt keep portal fans glued to their guns for many more hours.
Great mod, if a little under reaching, but they never set out to create greatness, just to create more. In essence a success and worthy of a home in anyone's portal mod folder.
