Qvke Borg is a Mork Borg expansion that adapts the setting to something like that of the PC game Quake.
The PDF is 44 pages, with some of the strongest art I've seen in any Mork Product. Every page is atmospheric and gorgeous. The images drip. The monsters are evocative. There's a cosplay photo worked in, and somehow it doesn't clash.
Layout-wise, this is in the classic Mork Borg style, so visual impression is emphasized over readability. However, the readability is still good. There wasn't anything I really had to squint and puzzle over.
Content-wise, there's a lot going on here. A good chunk of the book is full-page, lavishly illustrated monsters (a lot of which have mechanics that emphasize their persistence,) but there's also some cool lore linking the setting to the dying world, a new class (which is risky but has high damage potential,) new weapons (which don't disrupt the damage scaling of the core game,) new traps, and new trinkets.
There isn't an adventure, but the setting is naturally modular, and it's easy to play through a bunch of slipgate-linked randomly generated mini-dungeons.
Overall, if you enjoy Mork Borg, if you have a fondness for Quake, if you dig good art and layout, and if you want to add rocket jumps to your game, this is a fantastic pick.
