Overview

Doom: The Boardgame is a tactical combat game based on the id Software video game. One player controls the invading demons while the other players (1-3) play as Space Marines defending the Union Aerospace Corporation’s Mars base.

Turn Structure

The game alternates between Marine turns and Invader turns.

Marine Turn

Each Marine gets a turn with actions. On your turn, you may perform actions using your action points (typically spending movement or attacks).

Invader Turn

The Invader player activates invader groups, spawns new demons, and plays Invader cards.

Actions

Marine Actions

• Move: Spend movement points to move through spaces.
• Attack: Use a weapon to attack an invader. Roll attack dice matching the weapon’s profile.
• Open/Close Door: Interact with doors on the map.
• Pick Up Items: Collect weapons, ammo, and equipment from the map.
• Use Item: Activate special equipment.

Combat

• Attacker rolls attack dice for their weapon.
• Defender may roll defense dice based on armor.
• Damage = attack results minus defense results.
• Wounds are tracked; when a figure takes wounds equal to or exceeding its health, it is killed.

Invader Actions

• Activate demon groups to move and attack.
• Spawn new demons at spawn points.
• Play Invader cards for special effects.

Scoring / Victory Conditions

Victory conditions vary by scenario:

• Marines typically win by completing specific objectives (reaching extraction points, destroying targets, etc.).
• The Invader wins by killing all Marines or preventing them from completing their objective within the time/turn limit.

Special Rules & Edge Cases

• Line of sight rules determine what figures can see and target.
• Different demon types have unique abilities, health, and attack profiles.
• Marines who die may respawn at designated points depending on the scenario.
• Ammo is limited for some weapons; Marines must manage their resources.
• Doors block line of sight and movement until opened.
• Some scenarios include special rules for environmental hazards.
