I don't really know what's going on with this game... I played it for 20 hrs when I first bought it 2 years ago in June 2024, enjoyed it, fun enough. Then played it again this past weekend August 2026... and I didn't find any major changes... despite a deluge of update posts.... just not really sure what's changed lol, the vehicles behave better. The AI seems more aggressive. Guess I'll check back later.
Ich habe am Spiel nichts auszusetzen, ist für ein EA OK.

This and every other Pro feature is free until October 20, 2026. A free account is all it takes.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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.

great game one thing i would recommend is for co-op have one person be the base builder while the other be fps on the ground
6 years of early access to run this poorly is crazy
Fantastic game, very fun.
I’ve really enjoyed my time with Cepheus Protocol! It has a great tactical challenge and the new updates have definitely improved stability and unit navigation. If you’re into strategy games, I’d recommend giving it a shot!
Trying to enjoy this game is work, it didn't used to be. The legacy build isn't perfect by any means but it felt so much better to play in terms of how the zombies and infection spread worked. I don't feel like getting long winded so I'll point you to Ekiprax.'s review, nails it on the head.
Seems to be in a constant state of rework, whihch wouldnt be a problem if menus, gameplay and camera movement werent still feeling extremely janky. (i know camera is apparently getting fixed soon) the UI needs a MAJOR overhaul. i find myself enjoying the core concept of the game but it is simply painful to even look at. For me the game would be absolutely worth it if this issue is resolved in the future.
Erst war ich etwas skeptisch da es immer noch im Early Access ist nach 6 Jahren. Das Spiel hat Potenzial und ich hoffe das die Spiele Entwickler es weiter ausbauen und verbessern. Zum Gameplay selber die Einheiten sind sehr detailliert und jede Einheit hat ihre eigene Aufgabe, man kann sogar eine Einheit selber in der Ego perspektive steuern, dieser hat auch eine Skill system aber da habe ich noch nicht rausgefunden wie dieser auf levelt. Es gibt eine große Auswahl an Fahrzeugen und Helikoptern, es ist für jeden etwas dabei. Auch so kleine Detail, wenn sich die Soldaten vom Helikopter abseilen, sehr gut gemacht. Was man aber sagen muss die Helikopter haben manchmal Schwierigkeiten den Weg zu finden, wenn sie durch eine Gegend fliegen müssen wo es viele hohe Gebäude gibt. Manchmal fliegen sie sich fest aber das kann man leicht beheben. Die Aufgabe des Spieles ist die Leute aus ihren Stadtgebieten zu evakuieren und gleichzeitig die Zombies und Patient null aufhalten. Die Zombies haben sehr unterschiedlich Einheiten Vögel die von der Luft angreifen oder z.b. Moloch (Riesen Zombie) der einfach Betonmauern durchbrechen kann und nur mit Panzer und schweren Waffen besiegt werden kann. Dieser kann eure ganze Sicherheitszone einfach zerstören. Es gibt dazu auch unterschiedliche Schwierigkeiten wie z.b. ein Virus gas das sich ausbreitet und die eigenen Soldaten, Fahrzeuge infizieren kann, nur Soldaten mit Gasmaske sind davor geschützt (dies und andere Dinge kann man in den Settings einstellen). Durch XP erhält immer bei einem Stufenaufstieg Doktrinen punkte eine Art Freischaltpunkte mit dieser kann man dann weiter Einheiten freischalten oder Gebäude die man noch nicht bauen kann. Dadurch wird das Spiel interessanter da man zu Anfang nicht alles Fahrzeug und Einheiten besitzt. Es gibt auch ein Horde Modus für all die gerne endlos kämpfen möchte und jede Welle mehr Zombies kommen. Das Spiel gefällt mir sehr gut es gibt nur zwei Punkte die mich stören, das die die Spielkarten manche Maps sind schon komplett oder zu 80% fertig gebaut. (Auch mit den Autos und pflanzen alles schon detailliert angezeigt. Aber da gibt es Maps wie auch im Hauptmenü da bestehen die Gebäude nur aus grauen Vierecken, und man vermute nur das es ein Gebäude sein soll oder Zonen wo alles fehlt von verlassenen Autos bis hin zu pflanzen einfach nur ein trostloser fleckt. Klar zur Verteidigung es ist ein Spiel das noch nicht fertig entwickelt wurde, aber das muss man einfach ansprechen wenn man sich überlegt das Spiel zu kaufen. Ich würde das Spiel ein wenig mit Terminator: Dark Fate – Defiance, vergleichen auch wenn das Spiel noch lange nicht soweit ist, aber anleihen die Einheiten Details sind schon ein guter Schritt dazu, hier kämpft man halt gegen Zombies und dort gegen Roboter. Klar die Spiele sind technisch noch weit auseinander aber mit den Details von den Einheiten und Fahrzeugen sind sie sich schon sehr nah. Deswegen hoffe ich einfach das Cepheus Protocol eines Tages hoffentlich eine genau so gute Qualität hat wie dies andere Spiel. Hoffe dies hilft euch etwas für die Kauf Entscheidung :)
Honestly, Not a bad game. I acturally enjoy it. Please keep making more maps.
