Finally, we waited for this -
Portal 2 was released , a super puzzle from Valve.

Official sales in the CIS countries will begin from April 21, but you can already pre-order. I have so far met two versions of Portal 2:
light and
dark . (a cursory analysis showed that an icon was put into one, and a puzzle into another).

Mac users have a holiday today, everything will work on their machines too;)
System requirements, as always at Valve, humane (taken from Ozone):
Windows XP / Vista / Windows 7;
Dual Core 2 GHz / Athlon 64 X2;
1 GB of RAM (2 GB for Windows Vista);
7.6 GB of free hard disk space;
DirectX 9.0 - compatible GeForce 7600 GT / Radeon X800 / Intel HD Graphics 2000 video card with Pixel Shader 2.0 support with 128 MB memory;
Sound card;
Device for reading DVDs;
Keyboard;
Mouse.
Portal 2 is also available on
Steam , but the price is not very tasty (the cheapest version is $ 50).
