If you are interested in CS:GO check out the article below from the official CS:GO website. It goes over some frequently asked questions about the game.
Q) How can I get into the beta?
A) The beta is currently closed. The current stress test is to test for crashes with various hardware configurations and how the servers handle the stress. The best way to get into the beta is to be active in the current Counter-Strike communities.
Q)How do I activate the console?
A) Activate the console in Help & Options -> Game Settings -> Enable developer console. This will then allow you to open the console using the tilde key ~.
Q)How do I open the server browser?
A) The current version of the beta does not support a server browser. This feature will be added later.
Q) Can I host my own dedicated server?
A) Not at this stage in the beta. The full version of CSGO will allow community run dedicated servers on both Windows and Linux.
Q) How do I start a local game?
A) Click Play -> Create Match -> Choose your map and game mode. To have other players connect to you they will need to know your IP address and use that to connect in the console with “connect youripaddress”. The full game will have a server browser that will let you easily start local games.
Q)Can I make maps for CSGO?
A) Yes, there will be a new SDK available after the full game has been released. During the beta you can start laying out your map ideas with the current Counter-Strike: Source SDK.
Q) How do I report a bug in the beta?
A) Please use our steam forums for now.
Q) How do I play competitively?
A) To start with, we only support lan competitive play. Matchmaking into competitive play will be enabled later in the beta.
Q) Why does my crosshair change size?
A) The crosshair consists of multiple parts. The most obvious section is the dot in the middle which is used for aiming. The traditional cross hatch moves as you move and provides rough accuracy. The brackets represent the weapon accuracy at all times including being stationary and firing.
Q) Why can I sometimes defuse the bomb faster than other times?
A) On the counter-terrorist side if you are carrying a defuse kit it will halve the defuse time. The defuse kit appears as a small pair of needle nose pliers in the lower right corner of your in-game UI.
Q)What are the minimum and/or suggested system specs?
A) While we are still developing the game these are in flux. The early stages of the beta will help us better set those suggestions.
Q) Why aren’t the characters solid?
A) In Casual mode players can pass through each other as their bodies are not solid. In Competitive mode the player’s bodies are solid and they cannot pass through each other. This also allows for player stacking in competitive mode.
