What drives the score
How to read this
Every input gets a grade, S to D, read from the buyer's side. The score is multiplicative, so an input only counts as raising when it sits near the top of its own scale. Anything with real room left is holding the score back, because that room is the gap to 100. ▲ marks a lift, ▼ a drag or a dock, ? an input we do not have, • a fact this genre's score does not use. The exact weights stay secret.
The value story
It has never been cheaper than $8.99. That was March 2025. It has been discounted 23 times in the 4 years tracked here, typically at 70 percent off, with about 6 weeks between sales. Today it is at full price. The last sale was about 13 weeks ago, and on this game's rhythm the next one tends to arrive within 6 weeks.
It is pricier than 98 percent of its genre, and less well reviewed than 80 percent. The games it most resembles do better on the same math. Dead Space ($14.99, scores 53) and Dead Space (2008) ($7.99, scores 66) both outscore it.
Steam's global achievement data says about 3 percent of players ever finish it. On a 10.1-hour game, that is a lot of paid-for hours most people never see. Players rate it 65 percent positive over its lifetime, and the last 30 days run 73 percent. It is aging into a better game than its average suggests. Of the 800 Steam-purchase reviews this site sampled, 5 come from buyers who refunded the game, sampled from reviews written November 2025 to September 2026. Inside the two-hour refund window, 39 percent of the 6,275 reviews written there were positive, against 65 percent overall, and those are 18 percent of everything written about it. It sells extras on top of the sticker price (cosmetic); the score docks it lightly for that.
It carries Valve's Deck Verified rating and runs 10.1 hours, about as long as a handheld game wants to be.

What players say
Personally, I find it better than **Dead Space**. It has everything I want in a game: horror, suspense, a good story, great graphics, and that terrifying atmosphere of deep space. It reminded me of the movie **Alien**. The game is fantastic and definitely worth experiencing. It doesn't deserve all the harsh criticism it received.
Probably the best horror I've played, played through it twice now, hope they plan on making another to continue the plot 10/10 game would recommend!!!
Didn't like it. I was unsure about it from the start. I kept giving it more time but it was too repetitive and story was not that interesting. Eventually I uninstalled as it become too unenjoyable to go on.
Player reviews from Steam: the most helpful all-time, plus the newest that clear the same quality bar, with the hours each player had put in when they wrote it. The mix of Recommended and Not recommended follows the game's Steam ratio. Rotates daily. Opinions are theirs.

The Callisto Protocol™ scores 10/100 on the BANG Score (a skip). The BANG Score rates what a game is worth for the money. Via Steam BANGERS. https://steambangers.com/game/1544020/the-callisto-protocolThe BANG Score is one number for value, 0 to 100: price against how it reviews and how long it was built to be. It answers the money question and stops there; whether the game is for you is still your call.
Reviews set the ceiling and price moves you inside it, so a cheap game that reviews badly cannot climb. Ratings from few reviewers are shrunk toward the middle, so 100 percent from nine people does not outrank 96 percent from ninety thousand. Length comes from HowLongToBeat where it can be matched, measured against a per-genre floor so a five-hour narrative game is judged against other narrative games rather than against a sixty-hour RPG. Where no verified length exists the score says so and carries a dock, because the biggest input is then a guess. The full method, including where it is weak → Steam reviews as of Sep 15, price as of Sep 23.
