Dissolution (DISTION.WAD)

Bryant (aka "Gunrock") and Kevin ("The Solution") Robinson made Project Slipgate some time in 2001. It was a Quake-themed outing that explored the cool but sparingly-used (at least in the original campaign) "Complex" scheme as well as darker, disturbing fortresses. It also had something of a Doom 64 feel due to colored lighting, heavy atmosphere, and other aspects. The brothers decided to revisit the aesthetic with a side-story, released in 2002. Dissolution is yet another episode for ZDoom. It replaces MAP01-MAP07, though it's worth noting that the opener is a cinematic sweep of a fortress and neither requires nor takes any player input.

Project Slipgate (SLIPGATE.WAD)

Bryant and Kevin are the brothers Robinson. You might know them as Team Demise but I wasn't aware that they had a website until I started poking around for this review. They more commonly go by Gunrock and The Solution and they generally make levels for feature-rich source ports. (G)ZDoom, Vavoom, you know the type. Unraveling their development history has been a challenge because they are fond of going back and remastering their old works while eliminating the older versions. Where their debut, quake2doom, tried to bring the magic of Quake II to Doom, Project Slipgate worked with idtech2's flagship title. The most recent version replaces MAP01-MAP11, the same number but not slots as the original 2002 (2001?) release. It's built for ZDoom but the authors are fond enough of GZDoom's special effects that they recommend using it if you can.
