Plutonia Revisited Community Project (PRCP.WAD)

The Plutonia Experiment was a megaWAD created by the Casali brothers for id Software as part of the Final Doom package. In the years since, it's enjoyed a more favorable legacy than its sibling, TNT Evilution, so much so that it's had two unofficial sequels, Plutonia 2 and the WAD which this review covers, Plutonia Revisited. Plutonia Revisited's scope is a bit narrower than Plutonia 2, however, as the PRCP focused on vanilla compatibility (the trend of 2011). The only flaws you'll encounter when playing the original .EXE are a few maps that invoke the savegame buffer overflow (hooray for source ports!). In fact, this project has a few instances of mapping tricks that require vanilla emulation in source ports (notably some linedef hoodoo in MAP31). Redacted 05/01/12.

Doom 2 Unleashed (PC_CP.WAD)

Paul Corfiatis is a veteran Doom mapper, the author of ancient WADs like The Twilight Zone. Upon releasing his Whispers of Satan megaWAD with best Doom buddy Kristian Aro, he opted to start a community project, which debuted in 2011 as Doom 2 Unleashed. It's a forty map megaWAD whose last eight levels constitute their own episode, titled "No Hope for Peace". The scope of the project was restricted to maps that functioned in any limit-removing port and used only stock Doom II textures. I'm not entirely sure how the bonus episode is handled outside of ports that support maps in excess of 32, let alone custom episode definitions, but in ZDoom NHFP shows up as a selectable episode, backed by the soundtrack from Inferno.
