Tower Corp: a game of Dread

Dread has to be one of my favorite RPGs. Ever. It does survival horror PERFECTLY. But that's for another post.

Right now I have about 30 minutes until I'm going to run a game of Dread and I am nervous as hell! I'm not normally a nervous GM for RPGs. But this time I am trying two very dangerous things:

1. I'm trying to keep the game largely improvised. That means planning less. That means a scary feeling of no control.
2. I'm running a Zombie plot. Zombie plots tend to be fairly open-ended. And the last time I ran a zombie plot the game felt like a failure (I didn't have fun and from my point of view the players looked bored).

I am terrified and excited and eager for and dreading this game.

Here's hoping it works.

The basic premise:
The players are all employees of Tower Corp. After working late one night they are about to leave when suddenly a strange man (zombie) attacks one of them. The well-meaning security guard insists that everyone stay put until an ambulance and the police arrive. But instead of the police/ambulance, a team of pseudo-CDC types arrives and locks down the building.

They say that a CDC Incident Evaluation Team is on the way, but that's a lie: it's really a "clean up" team who are there to eliminate any witnesses or traces of infection.... with extreme prejudice.

Meanwhile, the players will have to deal with zombies and each other. Hopefully they'll want to investigate the cause/source of the zombies and find it in their workplace.

Dear lord I hope my players are willing to take as many chances as I feel like I'm taking with this.
