[Ongoing] Zombies? Look out!

You grab baseball bat quickly and head outside. Whoever it is trying to hurt another person, you would stop them and hear their explanation. If they using force, you too will do.

You walk near. The person screaming is probably a man. He seems desperate and scared. He won't stop shouting until he see you.

"Please... help me!" He is pushing other person on their neck using his arm. You stop your track abruptly. The attacker seems weird. He let out strange sound and shakes a lot.

"It's a zombie! Hurry and hit the head!" He wakes you from your daze as you immediately moves yourself.
