Straight in.

You grab a knife and get out the car and head straight to the door. Entering the house as the wave of adrenaline continues to push you recklessly onwards.
Your about to call out when you hear a scuffle upstairs, your brain suddenly comes back to action and you ready your knife and slowly and as quietly as you can manage creep upstairs.
The door to what looks like a bedroom is open and another scuffle comes from within. You creep to the doorway and peek round.
On the opposite side of the room is a scruffy, very ill looking man trying to work out how to open a floor to ceiling wardrobe.
As it wraps a hand round the doorknob you leap up from your crouch and charge knife ready.
You jump just as it releases the doorknob and begins to turn. You ram the knife into the figures throat as your body rams it into the wardrobe. As this happens there's a squeak from the wardrobe, then the zombie starts to gurgle, your knife stab wasn't exact textbook but as you pull the knife out and stab again, foul smelling blood pours out.
You stagger back from the zombie as it falls to it knees clutching its neck before falling forward. You kick its head just to make sure as you let out a loud sigh.
Suddenly as you do this the wardrobe door is flung open, smashing into the zombies legs as Milly jumps out from the wardrobe.
"OMG you saved me!!" She says as her arms wrap around your body hugging you to her body.
"Thank you so much, thank you, thank you..." You simply stand their at first as she hugs you and explains how she was packing and suddenly found the zombie climbing upstairs, she had already packed any weapon downstairs and all she could do was hide in the wardrobe, then from a gap in the door she watched as you killed it.
