I've done a bit of hex editing and config editing. I still know some old dos commands and I am learning Doom code and syntax by editing DEF and DDF files in Doomsday Engine and the EDGE source ports, respectively. I plan on learning DoomBuilder and SLADE in the future as well as C++, so I can make mods for Quake1 and Quake2 some day. I would like to create my own games in the future and work with an indie dev team at some point.
3 years and 9 failed rescue missions to Mars have not seen a single marine return. They were all sent in to find a lone survivor, dubbed the Doom Slayer...
