Gruntz 15mm SCI-FI is a dedicated 15mm fast play wargame designed for skirmish level play using combined arms. You can use miniatures from any 15mm SCI-FI manufacturer and the rules are not restricted to a set genre or background setting.  You can pick up, learn  and play Gruntz quickly and add to the basic rules with the included optional rules with more advanced movement, turn sequence and activation. 

This is the 1.1 release of Gruntz which has over a years worth of feedback and tweaks completed based on player feedback and further test games at conventions and with active players.  For the first time it is also now in print which you can purchase from the Wargames Vault.   There are new art works by Jake Parker in this release with story intro's to the various factions written by award winning author Jennifer Brozek. I was glued to reading the story intro's, they a great little sci-fi reads although you don't have to use the background information in the rules and can use your own settings and scenarios for your games. 

The rules were 88 pages long in v1 and have grown to a 135 pages with full colour examples, photos and map guides to play in this latest release. Gruntz has a points system and scenarios with unit builders for each type of vehicle and unit in the game. If you enjoy creating your own weapon payloads for tanks and mecha you can make use of the blank profile cards when creating your perfect unit.

Gruntz 15mm has been specifically designed to support tanks, support vehicles, air support, mecha and artillery. Vehicle rules are integral to the game and not a bolt on.  It is a combined arms gaming experience with support for all manufacturers of 15mm sci-fi and modern figures. 

Gruntz 15mm has manufacturer support from Critical Mass Games,  Ground Zero Games (GZG), Khurasan, Rebel Minis, Brigade, and Old Crow Models. The full range of figures are supported by the Gruntz rules including specialists, tanks, mecha, robotic, alien races, air support and air transport.

The rules and statistics in Gruntz cover modern and futuristic technology, allowing for low tech and high tech mixed battles. Included are statistics for alien technology and an introduction to the Heliopause setting.

You can build your own forces with the army builders and supplied blank profile cards. This enables any new manufacturer models to be designed and built with statistics which suit your own army with a points system which can be used or ignored if you prefer scenario driven story games.

Gruntz 15mmuses D6 die for rolling shooting and attacks with the core mechanic based on a 2D6 roll adding a number from the units statistics. Official counters are available for the game to enable easy identification of conditions on the battlefield.

The Barracks Application is now a download application available separately from the Gruntz 15mm rules. Details are available here

My experience with Gruntz was that it wasn't too bad as skirmish wargames go. We did have a problem at the time in the form of designing some vehicles which I think were not well matches (side to side) and, as we were designing to our minis, not to any effectiveness particularly in the ruleset, the fight didn't seem as even as we would have hoped. I would say that I hope in subsequent times, the author had the chance to add further guidance about vehicle construction and what will be the most reasonable sorts of designs. I didn't think our designs were too badly broken, but the fight that ensued kind of made us feel that way.

NOTE: This was early in the release cycle, so things may easily have improved since then. It's a really tough thing to create a good game with few places exploits can break the game and it is even harder when you allow players to build their own vehicles or units. Most of us have never heard of Lanchester Equations which is one of the few ways to comec close to a build system...See more

Does the publisher/developer have a new website? The one listed on this page is out of date.

Is it possible to add bookmarks to the pdf at all? It would make looking something up in the book a lot easier during play.

I'm trying to understand the rules.
When shooting with a Gruntz Squad against an enemy Gruntz Squad, do I declare what each model in my squad is firing at?
As in do I have to INDIVIDUALLY declare what each and every model in my squad is firing at in the enemy unit?

The product description says the book's size has expanded to > 100 pages, but the sidebar says it is 88 pages long. Which one is correct, i.e. what size would the book be if someone ordered it?

Probably too late to help you, but in case somebody else asks, my PDF has 136 pages.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
