I've been making games for a long time. The first was Final Doom in 1995, after which I joined Valve and worked on the Half Life series, Portal 2, Left 4 Dead 1 and 2, Team Fortress series, and other things in between.
Wow, this map took me over two hours! It has some immense battles which are really fun to navigate, but also some really tedious grindy sections. Let's not discuss the platform sections... Having said that, the map rewards thinking tactically and so is pretty satisfying to get through.
All of my Doom playthroughs are free range organic goodness - not tool assisted in any way other than the standard save/loads. Difficult fights with many attempts are numbered for full skill level disclosure :)
