Survival House by Necromancer

Welcome to essentially endless monsters with a constant supply of zombies. Also, once a Tor appears, another one will take its place every five minutes. (Don't worry, only one tor/starting location) There is a stash of supplies in the basement as well as in the garage. (Monsters do not spawn in the garage...although they may chase you there) There are some rooms, a closet, and a shower that you can enter. Don't forget to fight on the upper floor as well. Also be warned that you will be air raided every four minutes by...

Lastly, once you enter the basement... Enjoy!

(There is also an extra surprise in the basement from the start and every 10 minutes...what could it be?)
