6/10; above average unpolished jank on genuine appreciation of the genre. ~5 hours for 1 playthrough (3 endings) I truly enjoyed Zero Protocols aesthetics and gameplay for what they are; it's not trying to oversell you on what it is. It's indie System Shock with references to other horror franchises. You shoot like its 1993, explore the underground lab with a flashlight (including some nice touches such as it being difficult to read notes if the light is off), solve some puzzles. All of which I was absolutely down for. And almost everything else is wasted. 85% of the plot is back-loaded at the end of the experience. The sanity mechanic was basically forgotten about starting with Ch.4. Too resource abundant to justify it being low. Too long to decrease it on purpose. Having it low really only optioned you into extra lore and unnecessary loot rooms. $12 is perfectly fair for this game.

Zero Protocol is an excellent sci-fi horror with a heavy influence from System Shock with a smattering of Dead Space Pros + Amazing quality for one dev + Just the right length + Multiple routes and endings + Great story + Good visuals Cons - Not much, maybe a little more enemy variety, thats it really Zero Protocol is a must play for fans of sci-fi horror . 8.5/10

do not be fooled by the graphics, the attention to detail is excellent, if you walk in blood you make footprints, you can see yourself in mirrors etc.. splattercasting made me aware of this game and so pleased to play it strongly recommend and you will love the Easter eggs............

Sept. 2024

This is a fantastic sci-fi horror game that feels like a mix between Half-Life, System Shock, and The Thing with its gameplay, puzzles, and eerie environment. This arrived just in time for the Halloween season, so it's a great buy if you're looking to add to your horror collection.

I have only played the first two levels but the game has a great atmosphere, great gameplay, and it's scary! I got jumped a couple of times and it definitely spooked me. I played on the Steam Deck and it felt pretty good. I'd say the experience on PC would be better due to being able to aim and react quicker but it definitely runs well and works on the Deck. There are a couple of puzzles that made me rattle my brain and had me slightly confused but I got the gist. There's definitely hints placed around to guide you toward the answer for progressing. All in all, great game so far and excited to finish!
