A single player game from Valve. Set in the mysterious Aperture Science Laboratories, Portal has been called one of the most innovative new games on the horizon and will offer gamers hours of unique gameplay.
The game is designed to change the way players approach, manipulate, and surmise the possibilities in a given environment; similar to how Half-Life 2's Gravity Gun innovated new ways to leverage an object in any given situation.
Players must solve physical puzzles and challenges by opening portals to maneuvering objects, and themselves, through space.
Portal System Requirements
Processor: Intel Pentium 4 3.0GHz / AMD Athlon XP 3000+
Graphics: AMD Radeon X700 Series or NVIDIA GeForce 6600 GT
Portal will require Radeon X700 Series graphics card with a Pentium 4 3.0GHz or Athlon XP 3000+ processor to reach the recommended specs, achieving high graphics setting on 1080p. For your PC to completely meet the recommended requirements you will also need 1 GB system memory. Another thing to consider is the DirectX capability of your GPU. Portal needs a GPU capable of running DirectX 9.
