You always suspected the people you work with are undead, it turns out that was true.
It was a miserable place to work. You felt a pain in the pit of your stomach every morning on the way into work. You remained strong and your spirit was unbroken. Now, you are about to be tested in a way you never would have imagined.
You refused to go to the meeting. It’s a good thing you did, because everyone that went to that meeting has turned into zombies. Now you and your friends must defend yourselves!
You must survive. Set up automatic weapons from seemingly simple objects found at the office. They will fire at the incoming hoards of angry zombies.
