DOOM v0.7 Sneak Peek - Attacking

As I develop and refine the rules to DOOM RPG, and more importantly as I write those in a coherent fashion that can be easily understood, I will be previewing those rules here. At this stage in development, many core aspects of the game are solidified and have gone through initial testing. These game mechanics I can confidently say will survive into any expansive, semi-official rules releases in the near future. I hold back on others that are more experimental so as not to muddy the data streams with potentially false information. As you might expect from a ultra-tactical game such as DOOM, the Attack action is now grounded and in a state ready to be shown.


When a creature makes an attack, the active player rolls 1d20, plus a number of additional d20’s equal to the value of the attack modifier (-2, +3, etc.) If the modifier is positive, the active player may use any result rolled. A player can always choose to use a result from among the attack dice rolled that is of a lower value to activate a desired effect from the Attack Effect Chart. If the attack modifier is negative, however, the lowest value rolled must be used.

On a result of 10 or higher, the attack hits and deals its damage as indicated by the weapon being used. On every roll, whether a hit or a miss, apply the indicated effect from the Attack Effect Chart.

Example: Andy drops to the ground, Prone, and takes aim with his Assault Rifle to shoot a Flame Imp. He rolls a d20 for the attack, plus an additional d20 for the Assault Rifle’s Focused trait (+1), since he is Prone, and is able to use either die roll. He rolls a 13 and 11, both hits! He could hit with a 13, but he is lying on the ground Prone and is worried about a nearby Hell Knight stomping his head in. He wisely chooses to use the die roll of 11, allowing him to Stand Up and hits with his regular damage.

Multiple Targets, Multiple Attack

When an attack targets multiple targets, such as using a weapon with the Line or Auto-fire traits, use the following general guideline: once for the attack, once for the damage.

When attacking multiple targets, the active player must attack the target with the worst penalty to attack and apply that result against all targets. Similarly, damage is rolled only once and applied to all targets on a hit.

Held Weapon Only

A Marine can can only attack with his or her currently Held weapon, as indicated by the placement of the Items on his or her character sheet. A Marine can, however, activate any non-weapon Items in their inventory while keeping a weapon in the Held Item location.

Exception: An Unarmed attack may be performed no matter what the current Held Weapon is.

Demons have no such restrictions.
