As you are aware, the levels released may not reflect the latest versions of Revelations. Blaze spoke about a HDD/Raid failure, so we can't say the maps represent anything more than preliminary alphas.
He told me only the codes were lost, and as seen above he confirmed that most levels are the way they are now, nothing more than preliminary alphas.
But preliminary alphas are not, it's gotta be a pain in the ass to get rid of those annoying ass spiders.
I can't spell preliminary, but let me try to explain alphas. PikaCommando, these maps don't work. I'm not exagerating here, you can fall off most of the maps by making a wrong turn. I honestly don't see the point of playing them without clipping on. They are best described as map sections, i.e. chunks of a level that will be welded on to the main map once they function/ look alright. The one revelation map we had before this release spawned thiefs in a roomwithout stopping, no amount of spamming with explosives could change that. My guess is they had planned to use spawners the way psycho did. Not sure personally if we'll ever know for for a fact.
