MAP30: Excalibur (Eternal Doom)

Ok, let me just be the first to say that Eternal Doom rocks. However, this excalibur level is not fair to the players. I have found countless secret switches and various hidden passageways to no avail. I can only assume that there is a glitch in this stage as I have acquired every key except the blue keycard and red skullkey. There is absolutely no way down into the waters below without clipping mode off. you can't expect players to enjoy a level where you wander around with minimal fighting and just get stuck literally every ten seconds. It is (from the designers point of view) a cheap cop out. Instead of finding ways to make strategic puzzles, you have instead hidden switches where no one can find them unless they paste themselves on the walls and click several hundred times as they run along them. Even this would be okay, except the demos don't run and they have provided no walkthroughs. Next time just use regular puzzles, and for god's sake, make demos that work.
