This is the first version of my Half-Life mod (and my first mod being posted on moddb ever), so far it only has 5 maps. Every new version of this mod will add at least 4 more maps to the game.
This is version 1 of my mod, the mod is very short right now but more will come soon in the upcoming versions. Hope you guys enjoy it!
This is for the Steam version of Half-Life 1. Just drag the zip file to your Steam Half-Life directory (C:\Program Files\Steam\steamapps\common\Half-Life) unzip the file, then you should have a folder named girlev.1. Inside the folder should be the actual mod, move girlev from girlev.1 to your Half-Life directory. Just restart Steam, then it should show up in your Steam Library.
