I have been using map making tools and game editors for a good long time. Nothing more great than having new maps to use in you favorite games. I have had great maps I made in unreal to great maps in old school DukeNukem3D. (To bad that game only runs on my old computer) But anyways, the point of this thread is to ask if anyone here on kirupa has made half-life levels or better yet, half-life mods? And my main question is what would be the best to use for a program for this subject? The only two half-life editors I remember are Worldcraft and Hammer. Are there new ones or is there a different one to use to make mods? Or are these programs just the ones to do it?
