For you he waits, for you. A small map that is very easy to complete and is incredibly short. I'm new to half-life mapping, so do expect it to have (minor) issues.
yup, this is the official download. you will have to put the .bsp file in C:\Program Files (x86)\Steam\steamapps\common\Half-Life\valve\maps then open half-life and open the console and type: "map lvlpck1".
