May 2025
RPG ghost exorcising with deep impactful game mechanics and an extremely steep learning curve. What more could you ask for? This is NOT phasmo and this is NOT an easy game. Be patient and cautious as you learn all that you can about each of the 4 characters, the minighosts, the main ghosts, and how best to use your equipment to survive and successfully exorcise the ghost. Do you have what it takes to be on the toughest exorcist team yet???

This is a game mixed with Phasmophobia and Ghost Watchers mechanics. You can level up, use one of four characters. Each of them have their own skills and one ability. Also you have a vending machine, which you can use these red points after leveling up and then buy them with the ingame money. Really like these things. It's an okay game but I've had much fun with [url=https://steamcommunity.com/id/Flexus711/] my Obu ! Once you gain the knowledge of each maps and how every ghost and equiment works, every level difficulty becomes super easy. There up to 4 or 5 different main ghosts and some mini ghosts. At first the game is more scary than after playing for a while. But it is definitely worth buying and playing, to acknowledge some fun for a few hours. I really hope there will come some more updates wtih more content! 8/10 Get Goo Goo Alu!

As someone who loves Phasmophobia and other online co-op horror themed games this one makes me jump every time I play more than any other. One minute you're gathering cursed items, the other all of your friends are dead leaving you alone to finish the exorcism while in a panicked state. I cry. I also laugh a lot but mostly cry :,) Overall it is a good experience but I can definitely see room for improvement with more characters being added or newer maps and ghosts perhaps to keep the game alive and fresh.
