Duke!ZONE II
Loading up Duke!ZONE II expecting a fresh set of alien-shredding weapons or art assets will leave you empty-handed, but this 1997 add-on still packs three full episodes of stock Duke Nukem 3D combat designed to push your ammo reserves to the limit.
WizardWorks paid commercial price for user-level design in Duke!ZONE II
By 1997, the market for 3D shooters was flooded with commercial map packs. Simply Silly Software, founded by Joe Wilcox, took on the task of building an authorized expansion pack for Duke Nukem 3D. Published by WizardWorks, the resulting disk hit retail shelves containing three brand-new, seven-level episodes alongside a disc portion housing 500 fan-made maps scraped from internet archives.
What buyers actually got inside the box was a completely stock experience in terms of mechanics. There were no new gun models, no new enemy types, and zero custom textures or sprites. If you played action expansions expecting custom voice lines or weird new gadgets, you were out of luck. The entire product relied strictly on the standard Build engine assets already residing on your hard drive.
The total lack of custom soundtrack work hits you instantly upon loading into the first mission. The designers left the background audio track entirely silent for the original maps. Walking through sprawling structures with only the echoing sounds of your footfalls, pipe bombs exploding, and pig cops grunting makes the entire effort feel strangely eerie, or at best, hastily put together.
Three episodes deliver massive monster density and silent hallways
The core campaign of Simply Silly Software's project breaks down into three distinct thematic episodes, each containing five standard levels and two hidden maps:
- Arctic Assault: Moves through snow-themed locations like Outskirts, Slime Station, and Cop City before concluding at Showdown, with secret exits hiding A Quicky and 4 Way Stop.
- Alien Abby: Shifts into urban and religious structures, featuring Graveyard Shift, The Abby, Waterslide, Landing Bay, and Big Man, hiding Spelunking and Turn About as secret exits.
- Monkey Shines: Takes players through corporate and recreational spaces including Dining Out, The Company, Down and Out, Fun House, and the chaotic final map Nowhere to Run.
Level design across these episodes fluctuates wildy between clever geometry and outright map-editor chaos. A map like Cop City or Fun House might present an interesting premise, only to ruin its pacing by spawning dozens of high-tier alien commanders inside tiny corridors. Instead of clever tactical setups, difficulty is often inflated by sheer volume, forcing you to backpedal constantly down empty hallways while spamming devastator rockets.
This layout philosophy gives many maps an amateurish, unpolished edge. Puzzles often devolve into hunting for obscure keycards or shooting hidden wall cracks that look identical to standard wall textures. When a level works, the fast-paced combat built into Ken Silverman's engine carries it, but when a level fails, you end up wandering through quiet empty rooms trying to figure out which switch you missed.
Sequence breaks and jetpack shortcuts trivialize the uneven layouts
One consequence of rushed map architecture is how easily you can break level logic using Duke's standard gear. In the first episode, picking up a jetpack early on lets you float straight over intended trigger zones, bypass locked security doors, and fly directly to the end-level switch. Entire puzzle chains designed to take fifteen minutes can be skipped in fifteen seconds if you pay attention to open ceilings.
Finding hidden exits like Spelunking or Turn About often relies more on engine quirks than clever hints. Players who like searching every wall with the use key will find shortcuts, but anyone trying to play the expansion straightforwardly will hit massive brick walls of monster spawn closets. On the hard difficulty settings, you will burn through your shotgun and chaingun ammo within the first three rooms, leaving you dependent on shrink rays and pipe bomb traps just to clean out a single doorway.
The balance flaws make it hard to recommend to casual shooter fans, but diehard players in 1997 found a certain chaotic charm in the unfairness. Surmounting an absurdly overstuffed arena in Nowhere to Run using clever explosive bounces and movement tech brings a genuine sense of relief, even if the map layout itself violates basic rules of good shooter design.
A direct bridge to Nuclear Winter and shovelware box sets
Despite its rough edges, this map set served as a testing ground for the development team. Simply Silly Software reused their map-building expertise and technology pipeline from this release when constructing their next official commercial add-on, Duke: Nuclear Winter. That follow-up would finally introduce custom graphics and festive holiday themes, but the structural foundations were built right here.
WizardWorks also took full advantage of the compilation market at the time. They later repackaged this exact map collection alongside another add-on, Duke Xtreme, into a physical retail big-box release titled Duke: The Apocalypse. However, when the official Kill-A-Ton Collection hit retail shelves later on, the extra disc containing the 500 fan maps was stripped away, leaving only the primary campaign levels intact.
If you want a polished, perfectly tuned campaign, go play the original again. But if you want a grueling, unfiltered taste of late-nineties commercial map design where ammo is scarce and monster counts are absurd, this pack offers a bizarre piece of expansion history worth seeing at least once.
