Dare I do say this game is a full on masterpiece of a free horror game. It genuinely scared me to my core. There were some bugs with movement but they were fixed relatively fast. The game is dark and creepy and you mfs didn't know about the torch.... Not to mention the darkness is just horrifying, the way that mf just shows up out of the darkness and walks like Mr X from RE2 is quite intimidating and intense. It makes me feel as though theres always someone after me.

I agree with the others. It's too dark. Impossible to see more than 2-ft in front of you. I didn't see any in-game settings for this either. It's free though so you can see for yourself. YMMV.

Protocol Nadir is a surprisingly atmospheric horror game that made me enjoy the feeling of being lost. I explore an abandoned facility filled with randomly generated rooms, strange creatures and fragments of a forgotten story. I liked that the game does not simply point me toward the next objective, because having to search through the facility makes the whole place feel much more dangerous. Exploration is the main focus, and I spend a lot of time moving through corridors while searching for useful items and clues. The procedural room generation helps keep the layout unpredictable, which means I cannot completely rely on memorizing the route. I enjoyed that uncertainty because every new room can potentially contain something useful or something that wants me dead. The creatures are where the horror becomes more active. Some enemies can be avoided, while others force me to react quickly or find a way around them. I liked the balance between exploration and danger because the game gives me enough time to investigate the environment before suddenly reminding me that I am not alone. The mystery is also handled nicely. I gradually uncover pieces of the facility's history through scat…

"Protocol Nadir" is a low key asset flip, a bunch of other people's assets assembled badly to make a basic game, typically this kind of thing is done by amateur developers without sufficient budget, talent and/or staff to do the job of game development professionally. It's then quickly rushed into Steam Direct. And, unsurprisingly, this never results in a product with any quality, interest, or value for gamers. This is your absolutely typical Unity Asset Store asset flip, it's not a malicious one (no attempt made to get paid for someone else's Unity assets), but the quality is still a huge problem... this is a janky Unity kitbash, a bunch of assets on a first person adventure game blueprint that has you exploring a spooky hidden bunker. Notably the assets are arranged via repetitive, samey procgen instead of the developer doing the job of a developer and creating bespoke content, so that's another fail on top of the asset flip fail. So, the game might look better than you'd expect from an amateur project, but this is because it's partially or completely made up of stock assets, "borrowed" from asset stores and free asset websites. Very little in this game is truly the creati…
