ZOMBIE SQUAD is a zombie survival horror game based on the DUNGEON SQUAD system created by Jason Morningstar. Some ideas are
also from Alternate DUNGEON SQUAD by Liam Brennan.

Required items for play include someone to act as a referee, some players, pencils, paper and a dice set from d4 up to d12.


The dead have risen from their graves and now hunt the living to satisfy their insatiable hunger for flesh. Pockets of humanity fight for survival against the ever present undead hordes. Player characters represent these survivors.

Characters can be of either gender and can have any description the player and referee can agree on.

Each character has 4 Primary Abilities that are assigned a die value by the player (d4, d6, d8 and d10).


SURVIVAL: This covers the basic skills needed to survive in a zombie infested world such as will power, self-discipline and combat.
HEALTH: Physical endurance, aptitude and natural resistance to toxins and infections.
INTELLECT: General intelligence and ability to learn and use knowledge. Used for fixing/understanding machinery
PERSONALITY: The character’s looks, charm and general charisma.


HIT POINTS: Each character has a number of HIT POINTS equal to 10 plus half the value of their HEALTH die.

e.g. a character with HEALTH d10 has 10 + 5 = 15 hit points.

At 0 hit points a character is unconscious (and cannot perform any actions until healed above 0 hit points). A character will die when hit points are reduced to a minus figure equal to the highest value of their HEALTH die.

e.g. minus 10 hit points results in death for a HEALTH d10 character.

NOTE: Any character killed by a Zombie, and not completely eaten, will rise from the dead as a Zombie in the number of Rounds as per the character's original Health die value.

e.g. a HEALTH d8 character dies. He will become a Zombie in d8 rounds.


A character starts with their default language based on their country of origin and they may be able to know additional languages. Make an INTELLECT roll.

A roll of 1 – 3 means the characters knows only their native language. A roll of 4 – 6 means the character knows 1 additional language. A roll of 7 – 9 means the character knows an additional 2 languages and a roll of 10 means the character knows an additional 3 languages.

These additional languages may be any other foreign language (such as French, Japanese, Mandarin, German, Swahili, etc.) with the
referee's approval.


Characters start the game with two items of "Stuff." The "Stuff" can be anything a player may want, as long as it is approved by the Referee. Some common pieces of "Stuff" are a large wrench, pistol, axe, molotov cocktail, etc.

Assign one of the following values to each of the character's two items of "Stuff": d6 and a d10. A character may not have more than four items of "Stuff" at any time. The character may have as many normal items as they can carry.

eg. The player decides to give his character a d6 Machete and a d10 Shotgun. Another player decides to give her character a d10 Chainsaw and a d6 Old Service Revolver.

Most weapons do a d4 die roll for damage. If a player assigns a weapon to his "Stuff" then that weapon will do damage as per its "Stuff" die value. Weapons with other die value will be found during the course of the game.

Armour reduces damage taken by the amount of its die code.

e.g. A character wearing a heavy leather jacket is attacked by a Zombie. The Zombie bites for 1d6 damage while the jacket offers 1d6 protection. Should the zombie do 4 points of damage and the player rolls a 5 for his armour – he takes no damage from the


As the characters scavenge for survival, they may come across many useful items. This can range from weapons to medical supplies (perhaps they add +1 to Health rolls vs sickness and/or zombie infection) to food to fuel.

Characters also gain experience for every zombie killed equal to that zombie's HPs. These experience points may be spent to raise an
Primary Ability die value. To raise such a value costs 50 times the new Primary Ability.

e.g. A player wants to increase his character's d4 Personality to d6. It will cost him 300 XPs.

A player may also spend 50 XPs to increase his character's HPs by 1 point.


A TASK is any attempt at an activity that is neither instantly achievable or impossible. All TASKS are rated depending on their difficulty and require a number to be equalled or surpassed for success. The numbers are detailed below:

Easy 2
Normal 4
Hard 6
Very Hard 8
Nigh Impossible 10


Used when attempting tasks such as listening, sneaking, searching, determining another’s motivation or trustworthiness, and combat.


Used for resisting poisons, extreme fatigue, and infections (such as Zombie Infection). It is also used for physical activities such as climbing, jumping, swimming and lifting heavy weights.


Used for deciphering codes and puzzles, jury-rigging/repairing technology, and understanding additional languages.


Used for bribing, befriending, bullying or seducing others. Personal rolls work only on the living (no affect on Zombies).


Sometimes a TASK will be effected by the circumstances in which it is attempted. If this is to the character’s benefit it is referred to as 1 die higher.

e.g. A d8 is rolled instead of a d6, a d10 is rolled instead of a d8 etc.

If this is to the character’s detriment it is referred to as 1 die lower.

e.g. A d6 is rolled instead of a d8, a d8 is rolled instead of a d10 etc.

Should this result in a die lower than d4 the character may not attempt that TASK roll.

Should it result in a die higher than d12 the roll is attempted at d14. For a d14 simply roll a d12. Take any odd roll as is but add 2 to any even roll.

Above a d14 is d16 and d18. These are handled exactly as d14 except that at a 4 and 6 is added to even rolls respectively.

Modifiers stack with a higher and lower die modifiers cancelling each other out.


The origins of why the dead are reviving and attacking the living is left up to the Referee to decide. The following examples are just
suggestions and are far from being the only possibilities.


Perhaps strange alien radiation bombards the earth causing the dead to rise from the grave. Or a meteorite crashes into the earth releasing an alien virus that animates the dead.


The war to end all wars has finally happened. The world is a wasteland scarred by radiation and biological weapons. The survivors of this catastrophe now must deal with the dead who hunger for the flesh of the living.


Whether it is scientists meddling with things that man was not meant to know, or the military trying to create the super-soldier, or an attempt to cure diseases that went wrong… science has unleashed the greatest horror known to the world – zombies!


Perhaps it is the End Times and the dead have risen and are taking their revenge on the living. Or perhaps Hell is full and the dead no longer have a place to go. The world has literally become a Hell on Earth.


A zombie needs a roll of 4 or greater to hit a survivor. Zombies can be divided into four "classes" of difficulty: weak, average, tough and unique.


Zombies are "killed" when their HP reach 0. This represents the final fatal shot (in most games this represents the head shot). Naturally, the Referee may determine special rules on how a zombie may be killed (ie only by fire, or Holy Water, or a biological agent, etc).

OPTIONAL RULE: A character may attempt to hit the zombie's head and go for an instant kill with a call shot. The attacking character's Survival Roll is at –1 die value.

e.g. A character with d8 Survival tries to get a headshot on a average zombie. He attacks with a d6 instead.


All Zombies have an Infectious Bite attack. Should this bite score any HP damage on a survivor, then that player must make a HEALTH roll against the damage done or else the character will fall victim to the zombie infection.

e.g. A zombie bites a character for 4 points of damage. The character has d8 Health and rolls a 2. His character is infected and will become a zombie.

Any characters that do become infected will become zombies in the number of rounds based on their Health die value.

e.g. The above infected character now rolls a d8 and gets a 4. That means his character will succumb to the infection in four rounds and become a zombie.

OPTIONAL RULE: One possible optional rule when dealing with zombie infection is to allow no save should a zombie inflict any damage with its bite.

Or the Referee may apply a Task Modifier to the character's Health die value. Weak zombies have no modifiers, average zombies have a –1 die modifier, tough zombies a –2 die modifier, and unique zombies have a –3 die modifier.
