不是阿,完全抄襲另外一款後室遊戲!安捏乾丟 流程一樣就算了,重點還沒抄到精隨! 充滿著劣質的材質跟粗糙的關卡設計,真的很沒料!不建議購買
這是有史以來玩過最爛的後室遊戲,完全抄襲就算了,音效超級沒誠意,建模也有夠無趣!!!! 下面的好評留言都是虛假的!!!! 請不要被騙了!!! 有六個人可以一起玩又如何?死掉以後觀戰畫面超多BUG!玩到要吐!
我玩完了 完全抄襲另款後室的流程 建模敷衍 怪物各種迷之追逐 (毫無刺激感) 無過場動畫 下面所有評論的好評都是假的全刷出來的 浪費我人生中的兩個小時 剛好遊戲進度玩完差不多就是兩小時 根本就是騙人錢的遊戲 千萬別買 買了後悔 這麼好的一個主題還有辦法做成這樣 有夠無言
優化極差 怪物的罐頭音效極糟糕 想關掉音效也不行
I tested this game and i can say it's a realistic, adrenaline-filled experience , you can play it alone, with friends , without entities it really matches everyone.

Beat the game with 15% achievements. A fun backrooms game with around 15 or 20 medium sized levels, cool to play with friends and chill game to run around and explore in
There's some bugs in this game for sure but I had a great time playing co-op. Graphics are decent. A really fun game with friends.
I'll just say that this game is a must-have experience. I know it's a Backrooms game among so many others, but this one is very good. I won't make a full review of it, since I don't want this Steam page to be too long. The graphics are a whole world on their own. If you change them, lower them, or set them to the highest settings, the experience takes a different turn. The high shaders make it look like a real world. There are so many levels, and the mechanics, enemies, and exploration made me enjoy the Backrooms like the first time back in 2022, when everyone tried to make their own game. It's kind of an indie game, since I know the team isn't big at all, but it works perfectly. I'm not blindly overrating this game. It has some flaws, but from what I remember, they weren't that obvious and I didn't dislike them. The developer truly cares about his community, takes requests, and tries to do his best with them. I haven't played multiplayer yet, but even that game mode could be a game on its own. It's a good idea to have added it. You guys really should try this game, even the demo. I know I got the game for free, which sounds a bit selfish XD, but the price should be worth it. Finally, I'll add that this game is still in development and updates are released often. From the point of view of a new and still-developing game, it's becoming something great. I really liked it, but that's just my opinion :)
Would i recommend? Definitely. Its one of the best backrooms games i have played. It has multiple levels that vary immensely from each other and the graphics are astonishing! I would add more story to the whole game though… something for the player to understand their situation! One really good feature are the endings, it would be interesting for them to be integrated in with the story? A great feature is the multiplayer modes! But all in all i would definitely check the game out, its really fun to play with friends or alone!
This game is in developpement by 2 independents persons. The game is so cool and so dark, the developers listen to the players' opinions to upgrade it every day. I believe on this team for make a great game when it's will be completed.
