Hi, I released my old Half Life 1 Single Player Levels, but be warned: the graphics are poor, but the gamefun is high I think (at least for me :-P). The zip file contains 2 level packs with altogether 12 levels + 1 bonus level. Read the txts included in the zip to get to know about how to install it and please give me your comments ! RMF data are also included. Do what you want with these files.
