💡 GM Guidance: Using Zombies Effectively
Threat Escalation
- Early Game: Shamblers and walkers. Teach players zombie rules.
- Mid Game: Introduce special infected. Force tactical thinking.
- Late Game: Runners, sprinters, multiple specials. Test mastery.
- Boss Fights: Unique zombies with multiple abilities.
Encounter Design
- Mix Types: Shamblers + specials creates tactical depth
- Environment: Use terrain to create advantages/disadvantages
- Escape Routes: Always give players way out
- Resource Pressure: Make ammo scarcity real consequence
Balancing Difficulty
Zombie Count Guidelines:
• Small Group (3-5 players): 2-3 zombies per player for standard encounter
• Fast zombies: Reduce to 1 per player or less
• Special infected: 1-2 total, mixed with standard zombies
• Boss encounters: 1 special zombie + supporting standard zombies
Remember: Zombies aren't puzzles to solve - they're pressure that forces choices.
Stay and fight? Run and conserve ammo? Risk noise to move faster? The threat should create difficult decisions, not impossible combat.
