Half life 2 nocd updating steam
Included with some editions of Half Life 2 (and available as separate games for purchase under Steam) are some existing mods which have been remade based on the Source engine - Counter Strike: Source, Half Life 1: Source and Day of Defeat: Source.
If you're interested in developing Mods for Source games, the full Source Software Developer's Kit (SDK) is available for download under the Tools tab in Steam, and includes the game code needed to create Source Mods and edit maps among other features.
Given Valve's commitment to distributing software via Steam, all updates for Half Life 2 and other Source Engine games will continue to be available exclusively through Steam.
Copy Protection Steam is not only a digital distribution method, it also has built-in online verification for copy protection.
As long as you've legitimately purchased a game via Steam, allowed it to verify and update online, and you're using your own account to play on only one PC at any time, then you should have no problems at all.

Basically Steam is a small program which runs in the background and provides you with the ability to purchase and download full games directly from Valve, it checks to make sure that you are a legitimate owner of any Steam game you attempt to install or play, and it also checks to make sure your game files are the latest version available for that particular game and automatically patches your games to keep them updated.
For the most part Steam is an excellent and reasonably priced method of purchasing and playing games, so there should be no excuse for pirating these games.
