Half-Life 2: PORTAL (2007) PC (Standalone version - doesn't need Half-Life 2 to be installed!)

The game consists primarily of a series of puzzles which must be solved by teleporting the player's character and other simple objects using the Aperture Science Handheld Portal Device (the "portal gun"). The goal of each puzzle is to reach an exit point. The "portal gun" and the unusual physics it creates are the emphasis of this game.
In Portal, the player character is tasked to navigate through a series of rooms, using the "Aperture Science Handheld Portal Device" (sometimes referred to as the "portal gun"), a unit that can create an inter-spatial portal between flat planes; however, not all surfaces are able to accommodate a portal, and moving surfaces will automatically close any portal existing on them.

System requirements:
1.7 GHz processor,
512 MB RAM,
DirectX 8 compatible video card,
Windows 2000/XP/Vista

Uses just less than 2GB of hard disk space when installed. Open the 'RFG_Portal_Standalone.nfo' file in Wordpad/Notepad for installation instructions. Enjoy!
NOTE: Just installed this, and it runs splendidly! It does take five to ten minutes to extract/install, during which time you'll see a CMD/DOS window. When it's done the CMD/DOS window will display some ASCII art and a message 'Press any key to continue'. Then just click the new Portal icon on your desktop to run it.
I've checked this for malware/viruses/etc and it appears to be clean - but, as always, scan it for yourself for complete peace of mind. Better to be safe than sorry.
