Installation without Internet

Hi, I'm new to Half-Life 2 and was wandering if there's a chance to install it without having internet connection. Thank You

Unfortunately there is no way to install Half-Life2 without internet. Half-Life2 requires an internet connection for validation with steam, without it, you can't decrypt the game. Just take your PC somewhere that has internet such as a friends house, install and set Steam to offline mode and that's it.
