Haunt: The Real Slender Game (Haunt:TRSG) is a free horror game based on the popular
Haunt looks and feels exactly like Slender but with the addition of a more engrossing plot and storyline. Rather than just collect weird cryptic notes like "He's watching you", Haunt requires you to collect notes which guide you to other locations where the rest can be found. It has a broader range of sound effects and scenarios (such as Green Park and a Power Station) than Slender making it more engrossing.
You also have to collect more objects to make your way through the game such as batteries for your camera. Although there's no sign of Slenderman, you have to avoid an orb like creature who like Slenderman, can pop out at any minute, mash up your brain and end the game. The sound effects and static indicate when he's close. It's easy to get lost in Haunt as the clues sometimes don't make much sense or say much, but it still retains the edgy atmosphere that made Slender such a success.
Haunt is a must try for anyone that loved Slender.
