Void maps are awesome and some of these are among the best I've played; even the start map looks great. I highly recommend playing them with the Eta Carinae skybox, although the Hell skybox from Doom 3 works perfect too (it's not included but it comes with other maps like "The Five Rivers Land"). The difficulty is ok, some maps are harder than others but none are overwhelming, unless you play on Nightmare.

By the way, here's another map, a late entry to this pack: coag3_negke

I replayed City of Sins (coag3_rickyt23) as part of my chronological trawl through RickyT23's maps. What a superb contribution, and what a lot of very different combats squeezed into what after all was only competition-entry map. Looks beautiful, feels great. (I only found one of the three secrets.)

The map with the bouncing fiends and that infernal elevator is so damn HARD

Is Golden boy's map finishable? I got the message "third level now accessible", but there doesn't seem to be such thing.
