The endless office [REVAMP]

You didn't go to work yesterday because of something, you came for work to day but something feels off... everyone wasn't there, nobody was there except you. But as you enter the office, you didn't realize the doors have closed behind you, and there's no turning back.. It's time to explore this office to find out the reasons why everyone wasn't here, but when you hear a screaming noise after opening 10 doors, you realized. They were ALL dead. You hid. Main objective: get out of the office, and DONT let them catch you, BEWARE it is NOT the only one..
