All the parts are passed by shooting a button.

I don't understand how to open first barriers. At first time somehow I've got it opened, but after I've died I coludn't figure out how to open them again...
Well, the idea of this map is original, but gameplay is poor and level-design is rude.

I actually kind of liked the novel design and construction of this map. A bit more of a puzzle spiced up with enemies than the other way round; though one might not consider button hunting the most enjoyable kind of puzzle there is. But at least I wasn't lost for too long for it to get very aggravating.

I don't know, the construction is crude and some of the buttons are kinda lame; but I still think not too lame. In the end, I liked it and had fun, and that's what mattered to me.

this is map is okay to play through with a few neat ideas such as finding quake symbol buttons to shoot at to lift barriers in order to progress through the level. I liked the final battle of the map with all the fiends behind the blood soaked demon wall. I would give this map a 2 out of five rating and say it is worth a quick play through.

I got through this just fine; however, it took some trial and error. I like the concept of the map (removing barriers by accomplishing side missions); however, the map has some issues, like some buttons being almost completely camouflaged and "key" buttons varying from room to room. Plus, lighting in parts can range from almost seizure-inducing to pitch black (thereby hiding enemies). Regardless, once you figure it out, it's quite enjoyable. I uploaded a demo of a normal run, using a slightly different strategy than Esrael's, if it helps...

I agree with the previous comments: the map's concept is very cool, but the construction is crude. The puzzle-focused gameplay reminds me of Chip's Challenge, which is something I never thought I would say about a Quake map.
