CASTLE OLDSKULL - Oldskull Grid War


Can the valorous fighters and dwarves protect the party’s spell casters from twenty onrushing orcs?

Can the heroes outflank and Charge to strike at the orc chieftain?

Can the party actually battle in formation before they’re completely surrounded?

How many men-at-arms can move through a doorway into melee in a single round?

How many dragon slayers can really attack the dragon?

What is the range to the enemy spell caster?

How many archers can fire at the thief hiding behind a pillar?

What happens when the heroes counter-fire arrows into melee?

Has “theater of the mind” descended into chaos and player confusion?

Is it fair to kill a hero because the player misunderstood the Game Master’s description of the battlefield?

And just how big is a Fire Ball, anyway?

If these types of questions have ever vexed your game, Oldskull Grid War might be for you.

This tactical supplement clarifies the existing Basic/Expert rules with demonstrations of miniatures on a battle grid. Instead of adding more rules, Grid War clarifies the existing often-confusing guidelines through multiple levels of optional complexity. It does not turn the RPG into a boardgame; rather, it provides explanatory support for every combat maneuver, monster, spell, and magic item in the B/X OSE game. The role-playing focus of the adventure remains intact, with enhanced visuals that turn the game’s action scenes into exciting play-by-play freezeframes of strike, maneuver, and counterstrike.

Instead of waiting “for their turn” and stating a simple action, Grid War allows the players to work as a team to develop tactics, formations, holding actions, zones of control, aisles of movement, and cooperative defender facing. Players can see who needs help, where everyone is, what everyone is doing, and they can focus on the visuals of monster positions, vulnerable targets, terrain, doorways, and opportune areas for mass attack and defense. Spell casting is no longer guesswork, it is a demonstration of player skill, tactical decisions, line of sight, range, and area of effect.

You can use this supplement with fully-painted miniatures and sculpted terrain; or, you can use pawns on a chessboard. Lego, erase boards, glass beads, and computer screens can all benefit from the rules and visual examples featured throughout this tome. If you want your players to be fully engaged, without losing control of the state of play, Oldskull Grid War will give you the tools you need for full-on tactical battle gaming.

Another classic Old-School gaming supplement from Kent David Kelly and Wonderland Imprints, Only the Finest Works of Fantasy.

Requires Old-School Essentials Core Rules.

This looks like the tactical shot in the arm B/X could really use for the crunchier style play groups. Your supplements to the older editions really enhance the game Mr. Kelly.

Thanks Kevin, I hope you enjoy it. I tried to strike a balance between playability and complexity, so I hope it's fun for other groups to experiment with.

Product Information
File Size:
17.65 MB
Original electronic
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.
