Here I will list basic information to play Half-Life, such as: how to launch it, how to start new game, controls, etc. I will use old 1998 version of Half-Life because it has many cool features that are not available in Steam version. There are some minor fixes and changes, for example, the only thing that was changed in menu was design and background, so menu guide will be almost applicable to Steam version.
I. Launching Half-Life
For first, find Half-Life shortcut on your desktop. Its icon looks like greek lambda letter, or like russian L letter. Then click on in twice with your left mouse key.
II. Main menu
After opening the game, main menu will appear. There will be several options, like New game, Hazard Course (embedded to New Game menu, from here on I will write Steam version names in brackets), Configuration (Options), Load Game, Multiplayer (Find Server), Create Server (embedded to Find Server menu), Quit. I highly recommend you to begin with Hazard Course because it will teach you basic controls, environment, and weapons. We will use only New Game, Load Game and Hazard Course menus for this walkthrough.
