this game has a nice concept and i hope the devs keep up the good work (there were some bugs and freezes but its early access)
Ambitious but crap, had this game for several games now and with each patch it just seems to get worse.
The game is heavily based on reputation. As soon as something bothers the survivors, their reputation drops, and the “overpopulation” starts killing their own soldiers one by one, making the game unplayable. Now I have tons of vehicles just sitting around. :D
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!
Not a huge fan of the changes they keep making, so I can't recommend. The game was at it's best when it was "You are the Military in a Left For Dead 2 or World War Z esque setting, go fight the infection". Like by definition this should be a game that encourages you to hunker down in one area and holdback the infected by blowing bridges, establishing checkpoints to test civilians for infection, sending out teams into infected areas to recover civilians, the works. It should be a game of resource management and making choices to sacrifice neighborhoods as you slowly pull back to wherever your forward base is. Instead you just get building sized kaiju infected or bird swarms that basically make it impossible to just play the game as you want. Like this is a game about killing zombies and the Devs have reworked it towards that, but it kind of sucks. Take State of Decay as an example, as anyone who has ever played that game can tell you: killing zombies is just the busywork you do as you make supply runs or go recruit survivors. You have fun dealing with zombie sieges not because it's thrilling work to fight them, but because you planned ahead and have a level 3 workshop where you manufacture ammo, or plague cure to keep your survivors from dying from wounds. The endgame is never you getting matched, it's having fun once you've overmatched the zombie horde. I wish the focus of this game was on evacuating XX% of the city's population before the city gets napalmed or nuked or whatever, rate success on your level of people saved, not on fighting the super zombie or whatever. (Also Performance is terrible but most people have already commented on that)
I bought this on my Steam Deck - I saw some videos on YT and it looked cool. I work long hours so I like games that I can pick up and play (without needing to install plug-ins, etc etc). In my experience, it just doesnt work for SD and I refunded it after 30mins. It says Playable on Steam - but its not, at least for me. First issue: I couldnt even accept the T&Cs, I tried everything and it simply wouldn't tick the box. Eventually, I had to switch to Desktop mode which allowed me to accept it, but when I closed and re-loaded in Gaming mode I had the un-tickable T&Cs again. Therefore, I could only play in Desktop. Second issue: The Offical button layout didn't work. By this point, I was already sort-of done, but I loaded the game and I didnt have a courser, I couldnt zoom in or out. Faffing with button layouts and switching to Desktop is just a right ballache, which is a shame as I was quite excited to play this. Might try it again in the future if it becomes more fleshed out and "pick up and playable"
DAUMEN RUNTER WEIL ES !!!MOMENTAN!!! NICHT SPIELBAR IST. also meiner meinung nach ist das spiel nicht spielbar. tolles konzept macht bestimmt super spass wäre es denn spielbar. hab es gott sei dank woanders günstiger erstanden. irgendwann ist es spielbar dann schau ich noch mal rein aber momentan..,. es ist halt das wichtigste am spiel was nicht funktioniert und das ist die evakuierung. diese stoppt bei mir einfach nachdem ca 200 leute gerettet wurden. die busse bleiben einfach stehen und melden dass die basis "verstopft" sei o.ä. auf jeden fall wird die arbeit einfach unterbrochen.
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.
