I'm REALLY like the combat, especially the customisation!!! its scratching an itch ive had since warzone 2100 days, but as of now, the pathfinding is killing the potential of this game. Units will freely allow the enemy to completely overrun your base before deciding if they want to move to where you ordered them too 5 mins earlier because either they have to drive around 1 obstruction and just seem to become completely lost to the point that you may as well delete the unit all together and just re-buy it, or because there is some sort of conflict with mixing soldiers and vehicles. The devs have done an increadible job, and if they can get the pathfinding to be more responsive instead of suffocating, then I may have just found my new RTS addiction.
Great game, it still feels a lot like what it is: an early access, but i really liked the concept. Hope they improve how units move and position themselves with the environment, cuz it feels a bit silly to have troops just standing there instead taking cover like in Company of Heroes.
Thoroughly enjoy strategy games like halo wars and CMSF and have always wanted a zombie game that fell in line with something like that. This game does that fantastically. I will note that currently the game is buggy as hell, but the developers are actively working on it and have been incredibly communicative with players every step of the way. I guess the development team is a pretty small team that are doing this mostly in their spare time. So given the circumstances I would say they have made a pretty good game that continually gets better as the days go on. The developers are also incredibly receptive to customer feedback which you don't always see with game developers. If you have an idea or a suggestion about something that may make the game better, and you post it in a forum the developers might just add it to the game which I think is amazing. All together the game is not without its flaws, but for how fantastic the development team is about listening to their players and how they are actively trying to improve literally everything about the game. I'd say this game is pretty sweet and is only going to get better.
They have a great idea and I like the direction they want to take the game, how ever even for a pre release game it feels extremely clunky to put at best. UI can be really confusing and some game mechanics feel very unexplained and difficult to figure out. Also it keeps crashing extremely often which makes me have to jump back into my latest save and replay the last few minutes only to be able to continue for a few more minutes. Should not happen. I'm running it on a rtx 3090 with 13th gen i7. I can play cyberpunk but not this...
Nice Game!!!!!!!!!!!!!!!!!
KI und KI-Pathfinding absolut unbrauchbar was schade ist, da es sonst ein OK Spiel wäre.
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 :)
its hard to completely recommend this game, you need to buy their vision. it is unique, there is no other game like it. army rts where you have to stop an infection of zombies. you land, you build you base and defend and go on excursions. its fun and i enjoy the concept - but its a bit of junk. they also implemented a civilian rescue objective, but i have no idea how it works and there is no tutuorial so its anyones guess. i recommend it because it has real potential and the developers have committed to the game. hope they keep at it.
Every zombie fans dream. Military sim pre and post outbreak. Potential is Yuuuuuuuuge!
Ideia de jogo muito boa, me surpreendeu. Ponto negativo, é que não fica muito claro como ser feito as coisas.
