Bob Larkin has told us of his latest map release, Descent3, part of his Descent into Hell project for Doom 2. There's about four different downloads to choose from so head over to the page and figure out which one you need. The level was tested and functional in PRBoom, Vavoom, jDoom, ZDoom and Legacy.
This one is larger, more complex and harder than either of the first two and features fluid gameplay - meaning that if two different people play it, it won't play exactly the same for either person or the same for a person twice in a row. I put a ton of hours into the gameplay and lighting especially. For those who like maps with detailed lighting, you'll love this one. I tweaked this one specifically for UV so expect a fight and a couple of secrets. One last word of advice - conserve your ammo!
