Most of what I did during 2004-2012 was make free maps for various video games. My original alias back during those days were Funjob, eventually I turned my nickname into Fjmaps because people normally knew me from my maps. All of these games were Half-Life 1 and Half-Life 2 variants.  Most of the maps I made were role-play maps, but I also have some co-op maps. You can download most of my maps here, read up about their development, or even download some of the sources. These are the games I mostly made maps for.
