Eternal Doom (ETERNAL.WAD)

Eternal Doom began life as a 12-map episode for Doom II, produced by Team Eternal and under the direction of Paul Schmitz, the author of Artifact and Welcome to Hell. A number of WAD authors cleaved unto him, including Sverre Kvernmo, who is responsible for many of the new graphics (that is, the stuff not ripped from Heretic and Hexen). Eternal Doom was updated two more times, adding fifteen and six levels, respectively, to turn it into a mega-megaWAD. I know this project eventually came under the purview of Team TNT, but I have no idea when that happened. I'm guessing some time during the development of Eternal Doom II, but I have no basis for that assumption. For sure, Eternal Doom III was headed by TNT, given Ty Halderman's involvement.

The Titan Series

THE TITAN SERIES
by Jim Flynn

as featured in Super Serials

Titan Manor	Trapped on Titan
Mines of Titan	Titan Anomaly
The Farside of Titan	Trouble on Titan

The Titan series was released by Jim Flynn in six separate installments during 1995. Its maps take place on Saturn's most famous moon, hence the title. They follow the adventures of a soldier of the "Alliance", opposite the less scrupulous UAC, as he thwarts both the incumbent demons and easily-corrupted corporation. The explanations for his involvement and justification for lack of armaments become more humorous with each episode, until his pistol is a concession from the military whose hands are tied following an unfavorable evaluation by the psychiatric department (they refuse to believe his mission reports).

Trouble on Titan (TROUBLE.WAD)

TROUBLE ON TITAN
by Jim Flynn

Trouble on Titan is the final level in Jim Flynn's Titan series, encompassing two maps included in id's Master Levels for Doom II (Titan Manor, Trapped on Titan) and four freeware maps (Mines of Titan, Titan Anomaly, The Farside of Titan, Trouble on Titan). As usual, it's set on Titan, and furthers the notion that nothing good ever happens on Saturn's most famous moon. The fact that hostile aliens inhabit Titan has finally reached most of the Federation, except the psych department, who insists you're suffering from space psychosis. Since they lobby against kitting you out against your next entrenchment, the best you can muster is a pistol (of course), with which you must put an end to the trouble.

The Farside of Titan (FARSIDE.WAD)

THE FARSIDE OF TITAN
by Jim Flynn

The Farside of Titan is Jim Flynn's fifth map in his Titan series, though it's only the third of his non-commercial Titan WADs. The setting, of course, is on Saturn's eponymous moon. This time, you're infiltrating the Titan Farside Research Base where researchers were studying some alien technology (in Trouble on Titan, it's made clear that you were specifically investigating a communications blackout). From there? Who knows? I suppose you can steal the technology and raze the base to the ground...at your discretion.

Titan Anomaly (ANOMALY.WAD)

THE TITAN ANOMALY
by Jim Flynn

The Titan Anomaly is the second map in Flynn's freeware Titan series (and possibly the fourth in line overall). Following the destruction of Titan's mining facility, it turns out that the UAC (an organization rival to Flynn's Federation, apparently) discovered an alien structure on Titan, dubbed the Anomaly. A security perimeter was established around the area, one your employers want you to break into to see just what is going on. Your briefing points out such areas as the Security Holding Area, Visitor's Center, Science Admin Building, Security Headquarters, and Guard Barracks before the Anomaly Research Center proper. Looks like you'll have one Hell of a time.

Mines of Titan (MINES.WAD)

MINES OF TITAN
by Jim Flynn

Mines of Titan, by Jim Flynn, is the first map in his freeware Titan quadrilogy. Because of the Master Levels' staggered project cycle (it was put on hold while Shawn Green put together Thy Flesh Consumed), it's a bit hazy as to what came before what. What I do know is that, while none of the publicly released Titan maps mention Flynn's Master Levels (or that he even worked on them), the .TXT files included with his id maps mention Enigma, Interdiction Zone and Oracle, pegging their creation if not before the Mines of Titan, then at least concurrently. As such, this WAD is a natural followup to his Master Levels.

Trapped on Titan (TTRAP.WAD)

TRAPPED ON TITAN
by Jim Flynn

Where Titan Manor was an example of an adventure based within a single, large structure, focusing on puzzle-oriented gameplay, Trapped on Titan is a longer, combat-oriented adventure through a number of settings. It's got some puzzles, to be sure, but they're more intuitive, with the enemies providing the real challenge. Jim Flynn gave the two Titan maps from id's Master Levels for Doom II no canonical order, but I'd like to believe that Titan Manor portrays the marine infiltrating Titan to steal the alien technology, while Trapped on Titan involves escaping the forces of Hell after succeeding. Like Titan Manor, it uses Anderson's starry sky to separate its setting from Doom II's setting.

Titan Manor (MANOR.WAD)

TITAN MANOR
by Jim Flynn

Jim Flynn has a grand total of two submissions in id's Master Levels for Doom II. They compose the beginning of his Titan series, a set of maps occurring on Saturn's moon. In Titan Manor, a MAP01 replacement, the marine is sent to an alien building on Titan with the intent of recovering some highly-advanced technology, with which the Federation (the nebulous organization for which the marine works) expects to make incredible scientific advancements. It's a smaller map than Flynn's usual fare, and has unprecedented unity in texturing themes, I'm guessing a product of working with id.

Oracle... (ORACLE.WAD)

ORACLE...
by Jim Flynn and Scott "MadMax" Harper

Oracle is a two-map minisode for Doom II, replacing MAP02 and 03, by the duo of Jim Flynn and Scott Harper. I'm not sure exactly how the pair developed but looking in Harper's assorted .TXTs, it's likely he found a kindred spirit in Flynn, who appeared to be a source of inspiration much in the same way that Anderson influenced Flynn. Overall, I'd say these maps have two things in common. First, they tend toward more surreal, abstract architecture. Second, they are very puzzle-centric, in both good ways and bad ways. The first map is the main one, and it's VERY large, much in keeping with Flynn's design sensibilities. The second is much shorter, constrained to a small, circular area, but (as mentioned) it's similarly complicated.

The Interdiction Zone (INTZONE.WAD)

THE INTERDICTION ZONE
by Jim Flynn

The Interdiction Zone is a solo affair from Jim Flynn. It's a large level for Doom II, replacing MAP07. It's got a large selection of textures but the main area appears to be somewhat patterned after a library. Now, this wouldn't be out of place as part of his Enigma Episode, but as this was initially released as a Doom II level, I suppose he excluded it from Enigma (which is composed entirely of Doom II remakes of his early maps). As is typically the case for Flynn, there's some great, abstract design and plenty of puzzles to be had. It almost feels a bit like an adventure game at times.

Surrounded! (SURROUND.WAD)

SURROUNDED!
by Jim Flynn

Surrounded! is a curio for OG Doom, replacing E2M8. It's also the only WAD Jim Flynn made for the original Doom that he didn't convert as part of the Enigma Episode. Why, gentle reader? Well, it's a one-on-one fight with a Cyberdemon who you "have surrounded". Yep; Flynn of all people made an arena map. Aesthetically it's pretty boring, a giant octagon with cherry red siding alternating with some tech guts while you're ankle deep in water. There are four marble cubes bearing the IOS relief floating in the air in a square arrangement. They don't serve any actual purpose but they help make the architecture less deadly dull.

The Enigma Episode (ENIGMA.WAD)

Of all the authors I've ever played, Jim Flynn is my favorite, and will probably remain so barring some kind of crazy Doom PWAD renaissance where people are straining to make large, complex levels that have solid themes or surreal texture and color combinations. Of course, Jim is mostly popular as one of the authors behind the Master Levels for Doom II, which brings us to an interesting point. The Enigma Episode, published back in 1995, is actually a re-release of almost all of Jim's older maps for the original Doom, painstakingly transmogrified to Doom II. I haven't played the originals, but some antiquarians were kind enough to put them on /idgames back in the mid-2000s.
