About the game
One Late Night: Deadline continues the story of One Late Night, a horror/mystery game where you play the role of an office worker caught in the middle of the paranormal activity that has broken out in a seemingly ordinary office building. Freely explore the 5 story office complex that houses several different companies. Look for clues around the offices, read newspapers about local events, hack your colleagues emails – anything that might tell you something related to the strange happenings.
You arrive at your work late in the night. The rain is pouring down and a storm is closing in fast. Everyone has gone home for the day a long time ago, but the lights in the lobby are still on as usual. As you enter the office complex through the main entrance, you immediately feel the emptiness and begin to go over in your head “what the hell you are doing here in the middle of the night?”, when you could be at home getting some well-deserved sleep. However, while your mind is clouded with the details of your precious deadline, you are unaware of lurking danger in the building and what has occurred during the night. Something has been set free; something that’s not from the world of the living. The shadowy and long hallways beckon you as you attempt to unravel the mystery that has befallen the unassuming offices. Has everyone really gone home, or is someone or something still here?

One Late Night: Deadline brings you a parallel dimension where you might see things otherwise not visible to the naked eye. So, if things look bleak and you’ve lost your way, use your cellphone to tap into this mysterious second dimension and things will soon become clearer. But beware; you might see more than you wished for. - Computers
Along your way you will come across computers that can be manipulated. You can use these computers to gather clues and information by reading employee emails. However, some computers are locked and require you to use a password, but if you are stuck you can try to hack them. If you find a Hack disc it will help you immensely in the hacking process. - Drowsiness
When your eyes grow weary and you begin feeling tired, you can head for the nearest vending machine to replenish your energy. If you move around for too long without having a drink you will eventually collapse from exhaustion. Running will make you tired much faster. If you are lucky you might find Dexterity tablets that you can eat along the way and instantly restore your energy. - Doors
