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.

It's Not Dead Space Everyone had sky-high expectations when the first trailer for The Callisto Protocol dropped, and it was quickly labeled as the next Dead Space. Unfortunately, it failed to live up to the massive hype. At launch, the game was plagued with performance issues, stuttering, bugs, and a broken save system. Combined with heavy criticism of the melee combat and a weak story, it faced a wave of negativity. Because of this, I decided to wait. Picking it up on sale about two years later turned out to be the right move. After tons of patches, most of the technical issues were fixed. So, is the game actually good now? Well, it’s a mixed bag. Where the protocol gets it right: • Next-Gen Graphics: The visuals are easily the standout feature of the entire experience. It looks absolutely incredible with everything maxed out. From the dimly lit, terrifying corridors to the sweat dripping off Jacob Lee’s head, the level of detail here is amazing. They really outdid themselves in the graphics department. • Terrific Sound Design & Audio: The audio work is right up there with the graphics. The voice acting, the terrifying monster noises, the unsettling background ambience, and the heavy punch of the weapons are all of the highest quality, creating a great atmosphere. • Awesome Gore: As a horror enthusiast who loves high-quality gore, this game completely delivers. The developers clearly spent a massive amount of time on this system. Jacob can die in some of the most brutal, grotesque, and creatively disturbing ways imaginable. Poor Jacob. • The Combat is Fun: This might be controversial since so many people hated the gameplay, but I actually liked the combat system. It is heavily melee-focused and lacks depth, but once you learn the rhythm of dodging, perfect dodges, and counters, it gets a really nice flow. Combining the melee combos with the firearms made the fights intense and provided a great survival experience, in my honest opinion. Where the protocol fails: • Very Linear & Scripted: The game is incredibly linear with very little room for exploration. You just follow the main path, and while there are a few side rooms for collectibles and upgrades, they are never far away. A lot of the encounters are heavily scripted to feel cinematic, which completely kills the tension on repeat playthroughs. • Lack of Variation: Halfway through the game, you really start to notice the lack of enemy types. The game just throws the exact same enemies at you over and over again, which gets boring. The same goes for the weapons, which mostly serve as an extension to your melee, and the bosses, which feel incredibly spongy and repetitive. • Not That Scary: As a horror veteran who has been hardened by decades of scary movies and games, this game never managed to actually scare me. It has some tense moments and a few jump scares, but it never crawls under your skin—at least not for me. • Generic Story: The story is your standard, highly predictable "sci-fi horror in space" trope. It’s not strictly terrible, but it is very generic and bland. It’s a shame, because a compelling story could have really elevated the experience. • Zero Replay Value: Once you finish the campaign, you have seen everything this game has to offer. I had to play through it multiple times to hunt down all the achievements, and it became an absolute chore. I highly recommend sticking to just one playthrough. • Scummy DLC Practices: Selling the actual "true ending" of the story behind a DLC paywall is a terrible direction for the industry. To make matters worse, they even locked a bunch of the unique death animations behind paid bundles, which just feels incredibly greedy. The final verdict: At full price, The Callisto Protocol is definitely not worth it. However, if you pick it up on a sale like I did, the experience is decent now that the technical launch disasters and the broken save system have been patched. If you love sci-fi space horror and don't mind a linear, melee-heavy ride with zero replayability, it is worth checking out. It’s far from the next Dead Space, but it still is as close as you will get.

*The Callisto Protocol* is a very interesting game. I only played it because of the HDR mod **RenoDX**, which makes the game look absolutely incredible. The story is somewhat engaging, but it is nothing particularly special. I would also argue that the ending is poor and very predictable. The audio, however, is extremely immersive and does a great job of building atmosphere. Unfortunately, the game was incredibly unstable for me. It crashed constantly, probably around 40 times in total, which seriously affected the overall experience.

I didn’t play The Callisto Protocol at launch, so I’ve got no clue what kind of mess it was in back then. But jumping into it now — and knowing how things ended up for Striking Distance Studios — honestly just makes me super sad. Yeah, sure, the game has some weird design choices and a few “wait, what?” moments. But overall? It’s a pretty punchy, intense, genuinely creepy action-horror. The art direction absolutely slaps, even if the "critics" love calling it “derivative.” What really bums me out is that because people didn’t really get the game at launch, we ended up losing what could’ve been a seriously badass franchise — and a super talented studio along with it.

"Evolution doesn't happen in the lab, it happens in the wild." Maaan... This game. Let me put it straight: If you expect Dead Space successor then you will be greatly disappointed and if it was meant to be one, then it's worse in every aspect. This game is different, it is it's own universe and gameplay. Approach it with free mind and no expectations, you will be surprised with SuperB voice acting, cutscenes and graphics. Lore goes hard and progresses nicely once you pass half of the game (I really did not like the first half of the game, inventory management was a hell, damage sucked (Hardest difficulty), locations/objectives seemed so random and game felt like it has an identity crisis). Lots of weapon upgrades makes for interesting gameplay experience, even though the later weapons are just useless and don't bring anything good to gameplay... except for Assault rifle on a final fight. Also the more weapons you got, the more types of ammo is in RNG pool, clogging your inv. Lots of finisher/death scenes for all the gore enjoyers. You get stepped on a lot (Step on me some more Monster-San!). Enemies variety is rather rich and might seem quite overwhelming sometimes (they take a noticable inspiration from Dead Space types). For 100% achievement hunters there might be quite a hindrance as you will need to complete the game like at least 6 times (including a >>NO<< death run that's saved only once per start of chapter)... Proper ending hidden behind Last Transmission DLC: Absolutely hated entire DLC gameplay wise; lore wise it was nice and unique idea that I can't say anything wrong about. Overall the more I played the basic game, the more I started to like it, the atmosphere, resource management and entire survival feeling, pity for the mediocre DLC. PROs: ++ Voice acting ++ Cutscenes + Graphics + Sound/Music + Gore +++ Final credits song CONs: --- Janky Melee combat (for such core mechanic there is so MANY issues) - Some questionable boss fights that suddenly rely heavy on shootings while 90% of the game focuses on melee - Camera when fighting in close confines - Lack of control who you attack when surrounded -- Shooting tentacles after finishing melee combo needs a total rework since it aims at weak point automatically and not tentacles PS: This game tried to be in PUBG universe, like what the hell, you can't imagine the suit idiots running those gaming companies. They tried so hard but failed entirely, proclaiming it is it's own IP in the end, but so deep in development they had no other choice than letting the assets in, as you still find a lot of PUBG easter eggs there that make no sense in the game itself at all. PSS: Any price tag with under 20 euro (including ALL DLCs) is reasonable enough. There is so many things right and wrong with this game, I would give 6-7 biophages out of 10.
