the game desperately needs a proper tutorial the idea is fantastic the game itself looks good but just dumping you onto a map and leaving you to figure it out is a big ask for me it made it unplayable so i refunded it as soon as they get a tutorial sorted ill rebuy it in an instant and change this review it just right now its very difficult to get into and kind of unplayable
For a game that released in 2020 its shockingly under finished. No campaign, no tutorial just throws you into a mission with no pointers or any help. Potential is there for an amazing apocalypse game but seems the devs have forgotten the basic requirements for a game and just smashed updates out for what little is available to play.

For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

1,000 Hours on this game and I have to say, it's overall a very entertaining game made by a very small part-time DEV team that works on this alongside real-world jobs and commitments.... The game is currently going through a massive rebuild and the Civilian Evacuation System that was a core of the original game has been added recently with many, many improvements and additions, the game is very much coming along nicely and is taking great shape, the addition of Co-Op modes and improvements to the 3rd Person Operators is a great way to have fun with friends or find new CERC Operators to fight the spread of the Infection... As a big enjoyer of RTS games and the Prototype Series, the ability to combat an Infectious Biological Outbreak, while managing Military Combat Operations and Civilian Protection and Evacuation Operation is what I really like about this game. I recommend this game for anybody who likes the above style of games if you head over to the discord, the DEVs are very active and the community as a whole are really helpful and welcoming. (On a sidenote - many of the Screenshots on the Storepage are actual ingame images, taken by ME, during some of many hours in the game, more can be found on the Discord for Player Screenshots here - https://discord.com/channels/469412014427602944/1430256470812786848
wanted to really like this game saw some gameplay thought yeah thats my thing for sure, set up a nice base in the port got it all looking good defensible all the evac buildings down, sweet. sent the buses out to start bringing people in and they just did whatever they wanted, drove off into the city never to be seen again. okay maybe thats my bad maybe i was supposed to put down a waystation, did so in a nice open area so they wouldnt get confused... no they pick up civvies then dump them off the pier XD. its got legs and its got potential but the bugs and lag are a bit too much to make it one for me just yet. i think if the pathing was a bit healthier i could tolerate the lag but twas not meant to be. im sure down the line with some improvements i will pick it back up the concept is definitely appealing
game dev to focused on other projects related to game to actually finish making the game, then complains they need more money to finish game so the sell cosmetic packs then they spend that money on making a standalone companion app to link to unfinished bare bones game.
I really wanted to enjoy Cepheus Protocol, but in its current Early Access state, I can't recommend it at £17.75. The biggest issue for me was how the game just throws you straight in. There's no proper tutorial, no explanation of the mechanics, and barely any context for what's actually going on. Basic gameplay systems like spawning troops, constructing buildings, producing tanks, calling in helicopters, and many other core mechanics were never clearly explained. I found myself having to stop playing and Google how to perform actions that should have been introduced naturally through a tutorial. The menus didn't help either - they felt cluttered, unintuitive, and confusing to navigate, making it even harder to understand how the game was supposed to be played. I do respect that the developers are actively working hard on the game, and it's clear they're passionate about improving it. However, it's also worth pointing out that Cepheus Protocol has been in Early Access for around six years. At some point, players should reasonably expect a more polished and welcoming experience, especially for the current asking price. The core ideas are genuinely interesting, and I can see the potential underneath it all, but right now it feels like you're paying to beta test a game that still needs a lot of work. A better onboarding experience would go a long way toward making the game more approachable. At £17.75, I don't think it's worth the investment in its current state. I'd recommend waiting until the game reaches its full release, or at the very least until it's available at a hefty discount. Hopefully, by then, the developers will have added a proper tutorial, improved the new-player experience, and polished the game into what it has the potential to become. For now, I'd save your money and check back later.
What a weird, awesome game. I am always baffled by the new little options, and lovely details that are brought in. Sure is rough, as it is early access, but one of my most favorite games I believe.
6 ♥♥♥♥♥♥♥ years and it's still as yanky as the first day.
Salgının Ortasında Askeri Bir Kabus Halcyon Winds tarafından geliştirilen ve erken erişim sürecini kararlılıkla sürdüren Cepheus Protocol, klasik gerçek zamanlı strateji (RTS) formülünü üçüncü şahıs nişancı (TPS) unsurları, hayatta kalma korkusu ve zombi salgını temasıyla harmanlayan iddialı bir bağımsız yapım. Pandemi temalı yapımlara ve Plague Inc. vari senaryolara askeri bir perspektiften yaklaşan oyun, oyuncuyu kontrolden çıkmış bir adada hayatta kalmaya zorluyor. Peki Cepheus Protocol masaya neler koyuyor ve erken erişim yolculuğunda nerelerden geçerek bugüne geldi? Konsept ve Hikaye: P-9 Virüsü ve Zalesskij YarımadasıOyunun arkasındaki temel senaryo son derece kaotik: P-9 adı verilen ölümcül bir virüs, Pangu Virusu olarak da bilinen bir salgınla Zalesskij Yarımadası'nda hızla yayılıyor ve insanları agresif mutantlara/zombilere dönüştürüyor. Biz ise askerî araştırma tesislerini korumak, enfeksiyonun yayılmasını engellemek ve "Patient 0" (Hasta Sıfır) krizini kontrol altına almakla görevli elit askeri güç CERC (Civil Emergency Response Corps) birimini yönetiyoruz. Oynanış ve Temel Mekanikler: RTS ve TPS Hibrit DeneyimiCepheus Protocol’ü piyasadaki diğer strateji oyunlarından ayıran en büyük özellik, mekanik çeşitliliği ve sunduğu hibrit yapı RTS ve Karakter (TPS) Kontrolü Sadece yukarıdan bakış açısıyla ordularınızı yöneten klasik bir RTS değil, aynı zamanda sahadaki özel kahramanları/operatörleri (Operators) üçüncü şahıs nişancı açısıyla doğrudan kontrol edebileceğiniz RPG ilerleme sistemine sahip bir yapı sunuyor. Bu operatörler yetenek ağaçlarına (Doctrines) ve özel yeteneklere sahip. Karantina ve Üs Kurma: Şehirde karantina bölgeleri kurmak, sivil tahliyelerini yönetmek, İleri Harekat Üsleri (FOB) inşa etmek ve lojistik hatları korumak zorundasınız. Ancak enfeksiyon yayıldıkça kontrolü kaybetmek an meselesidir. Agresif ve Dinamik Tehdit: Zombiler sadece basit birer hedef değil; sürü zekasıyla hareket eden, sese ve ışığa duyarlı, mutasyona uğrayabilen tehlikeli organizmalardır. Yanlış bir askeri hamle, tüm üssünüzün zombi dalgası altında kalmasına yol açabilir. Gelişim Süreci ve Modern Durum Oyun, ilk yıllarındaki ham halinden (Legacy sürümleri) sıyrılarak oynanış hızını artıran, kooperatif (Co-op) desteğini ve modern arayüz düzenlemelerini (harita rotasyonları, minimize edilmiş yönetim panelleri, kaydedilebilir kadro kompozisyonları) içeren geniş çaplı güncellemelerle (Pacing ve Rebuild süreçleriyle) çok daha kararlı ve dinamik bir yapıya evrildi. Geliştirici ekibin sürekli yayımladığı yamalar ve topluluk odaklı dengeleme seçenekleri, oyunun sert zorluk eğrisini oyuncunun tercihine göre esnetmesine olanak tanıyor. Eksiler ve Zorluklar Optimizasyon ve Performans: Oyunun geç safhalarında (late-game) harita üzerinde binlerce enfekte ve asker aynı anda hareket etmeye başladığında, özellikle büyük çatışmalarda performans düşüşleri (FPS dropları) yaşanabiliyor. Sarp Öğrenme Eğrisi: Lojistik, ordu yönetimi, enfeksiyon yayılım hızı ve üs savunmasını aynı anda koordine etmek yeni başlayanlar için oldukça kafa karıştırıcı ve cezalandırıcı olabilir. Sonuç Cepheus Protocol, askeri strateji ile zombi hayatta kalma unsurlarını sert bir haritada birleştiren, özgün ve cesur bir bağımsız yapım. Eksikleri ve erken erişimin getirdiği pürüzleri olsa da, sunduğu taktiksel derinlik ve kaotik atmosfer, strateji tutkunları için göz ardı edilmeyecek bir alternatif yaratıyor. Eğer askeri üsler kurup salgına karşı karantina protokolleri uygulamayı, stratejik kararlar alıp sahadaki birliklerinizi yönetmeyi seviyorsanız, Cepheus Protocol göz atmanız gereken yapımlar arasında yer alıyor.
