Extend the Story - Add a Room

"Rico, that man." you blurt, it was even hard to talk.
"Oh, you're up! I thought I was gonna lose you, oh man." Rico replies joyously. Tears even start to fill his eyes, but he wipes them away immediately.
"That man, Rico, he needs our help." you tell him. You struggle to point to him, but your arm hesitates to. That crash really did a number on your body.
"That's not Dave anymore Vince. Just some lifeless shell of human," Rico responds disgusted. Dave? Dave! That is him, isn't him. Why are we leaving, we should be helping. You struggle against Rico, but he's way too strong at the moment. Suddenly, Rico drops you onto the ground. You yell in pain, your leg throbbing more than ever.
"Dang it, we're surrounded!" Rico yells. You see in the distance a figure walking towards you, they were terribly bloody and groaned, unable to form words, He looked dead, but he wasn't, he was walking. You've read stuff like this in comics, but never thought it would happen. Could it be? A zombie apocalypse?

-You realize the zombie apocalypse has started
