So I, along with I'm sure others have thought about a more DnD style playthrough.One of which has a non-player as a Dungeon Master. This non-player will lead the survivors through scenarios customly crafted by the non-player (I will, for the most part, guide player through as the game does). I would imagine this play style will involve more creatures. This will lead to more items, and probably a slightly different combat/health system which may be played with polyhedral (DnD) dice. I'll show an example of what I mean:
You narrowly escape the tanker as it crashes into your vehicle. The tanker crushed your vehicle as if it were a made of bittle aluminum. The tanker turns over and spill fuel everywhere. With the sparks and flames it is only a matter of seconds before the whole thing blows. You sprint for a second and jump for cover, without a moment to spare the tanker explodes, briefly lighting up the night sky. There is no time to rest as the sound attacks nearby zombies.
~A flaming zombie is place closest to the survivor(s), with 4 others down the road. Every turn has more zombies crawling into the map.~
What will you do?
~The survivor(s) decide to run past the flaming zombie.~
Roll to Evade: d20
1-4 Roll Failed: Bitten
5-8 Roll Failed: Bitten, push zombie back
9-12 Roll Success Evaded Zombie
13-16 Roll Success Push Zombie
17-19 Roll Success Push Zombie, Zombie Falls and becomes a Crawler
20 CRITICAL ROLL Push Zombie on the Ground & Head Stomps, Killing Zombie
~Rolls an 18.~
The zombie lunges towards you, however you are too fast and the zombie, in such a rush to sink his teeth into you, trips itself and falls to the ground.
~Survivors make their way down the road and decide to shoot the zombies.~
Roll to Shoot: d20
1-5 Roll Failed: Zombie staggers toward the survivor(s) 2 positions, if Zombie is in the same position, instant bite.
6-10 Roll Failed: Zombie moves towards position, if in same position roll to evade.
11-15 Roll Success: Body Shot, 1 Damage
15-19 Roll Success: Body Shot, 1 Damage, Pushes Zombie
20 CRITICAL ROLL Headshot! 3 Damage
~Rolls an 15.~
You aim your weapon at the zombie and fire. The bullet finds its way into the shoulder of the zombie. While it doesn't look like you did much damage, the zombie staggers back.
~After firing a couple times the survivors defeat the zombies and move on~
You make your to a door, above it says, "Kendo's Gun Shop" and decide that's as good of a place as any.
If Kendo is a part of your team: (More items are revealed)
Kendo is relieved that his shop isn't in shambles. Being the owner of this shop he tells them where his ammo stashes are. [GO TO: If survivors grab ammunition]
If Kendo is not a part of your team: (NPC)
You open the door, hoping to find weapons, and you do. However this weapon is pointed right at you.
You hear the cocking of a shotgun. As you stare further down the barrel you see a man. He is a bulky man who looks like he could have held his own in a fight.
Kendo: "Who are you!? What are you doing here?!"
Kendo: "Ooh.. Sorry about that... I thought you were one of them."
~Survivors can ask what happened~
Kendo: "I don't have a clue. By the time I had noticed that something was wrong, the entire city was infested with zombies."
~Or ask how to get to the RPD~
Kendo: "You can take the door over there in the corner, you'll have to do down a couple alleys, but I'll take you to the Police Station."
~If survivors grab ammunition~
As you grab the 15 rounds of handgun ammunition you hear the crashing of glass. 4 zombies have broken the standing window glass and make their way into the shop.
~If Kendo is an NPC~
One grabs Kendo from behind and bites his neck. He jerks his shoulder and smashes the zombie in the face. He fires off a round blowing the zombie's chest cavity into bits of bone and pulp. However the other three walking husks grab on and overpower the big gunshop owner and bring him down. You hear his screams deafen into a gargling silence as their teeth tear into his throat and body.
~If survivors decide to just leave~
You exit the building and make your way down an alleyway. You hear glass breaking not far in the distance. Followed by a gunshot, then a scream, and then.... nothing.
This is all obviously works in progress. Especially the dice rolls. I'm open to ideas and critiques. The game will play pretty much as the standard game. Move 4 actions, 2 max for attacking. Zombies will move towards you after each turn. The combat is the biggest change. The tension deck remains but only the non player draws and he can make decisions/story based on the card drawn. Please share your thoughts and ideas! Sorry for the long read/post.
EDITS: Hero's suggestion of having the zombies constantly spilling in at the very beginning to give the players a sense of dread and urgency.
