So, if your playing yourself in these games . . .

What happens to the game when one of the players gets killed?

Side note -

I love this idea. These games look great. Can't wait to get them all!

When you die in the matrix...

Gm: "sorry, Bruce you are out of the game." * takes out pistol*

Gm: "sorry, Bruce you are out of the game." * takes out pistol*

Well...that escalated quickly. LOL!

You make an npc survivor?

Well then, when it happens in reality, everyone will know not to put any faith in you

The way I'll do it would be that I become the first zombie they encounter, right there on the table. Let the players deal with me and then continue running the game as normal.

Or make yourself the case of it all.

A character dying early in the game would kinda deserve it. (Unless it's from one of the scenario's "bite" mishap, but that can be solved with losing a limb.) As the rule system gives a lot of control to the GM to refrain characters from dying too fast.

But it could very well be a problem if the PC's end up in a situation where it's very likely one will die and it's still the best choice they have.

Like "ThenDoctor" suggested,

I was thinking of letting the character tag along with a "backup" character of a generic civilian until the original cast would all be dead, ending the game in failure (or success, as this game is really about all the players being eaten while having fun).

I just get them to make another PC character. Eventually you will see more survivors so... (But what about his origional character)? Well sucks to be you, either your group is a bunch of jerks or you died of your own stupidity. Either way, your group will remember you dying or leaving you behind.

For example, One of our group members saw a zombie at the end of a hallway, he ran towards it to Sack it to the ground (Which was successful, but he didn't see the other 2 zombies roughly 10 feet on either side of the zombie he tackled.) He was eaten pretty quickly. "What about my Character???" he says. "well your stupidity got the better of your character, feel free to create another PC but you are now considered dead in the game". I replied.
