Mazu's map was fun as always and stickflip's Decerebration left me wanting much more. Beautiful architecture, nice lighting and smart combat setups. I liked Shades' map as well, but ran out of ammo as seemingly some others also did.
Very fun pack consisting of both tricky and more standard combat and exploration type maps that are creative reactions of E1M4. Nitpicks would be some ammo placements in Shades' map, the very precise timing of managing your suit in Solipsist's and perhaps the progression post gold key sequence in Lobotomy Lobster's.
