Reviews, worldwide (the counter carries no country): 1.13/day in the week to Jul 21 → 1.4/day in the week after.
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.
About
Humanity emerges, hesitantly, into ruination. Almost nothing is left of the world as we knew it—settlements, forests, seas, mountains—all have been blasted into unfamiliarity. Horribly mutated animals hunt in packs through deformed woodland. Decrepit military robots stumble unknowingly through the ruins, sensors and logic centres blown. Alien soldiers, once impossibly powerful, cower in the wrecks of their ships, praying to heedless gods for rescue.
Control the survivors of humanity in a near-future apocalypse of alien origin. Pick a path between the indifferent abominations of the Voice and the uncaring automata of ZEPHON, with city management, turn-based tactical combat, unholy research, diplomatic maneuvering, and branching narrative quests. Gather your allies and pick your actions wisely.
On the planet Earth, that was once a cradle of life, the extinction of humanity is at hand.

Individually we were no one, together we are god itself. Woo us, fear us, worship us… these are all acceptable answers to the riddle of what you can do for us.”

I would love to leave a comment about how I loved the game, but I never got to play it. Game goes to initial load screen and then just sits there forever, can't even get to main menu. Tried reinstalling, tried verifying. Not a hardware issue. I don't have time to troubleshoot such a basic issue for a game. Apparently lots of other people have issues with the game not loading or freezing on loading screens.
What I don’t like: — Lore. Too convoluted, too alien, with the couple of human factions that are hard to relate to. It’s not clear if this setting stems from the world we know, and if yes, for how long it is in this state and where are all the old world actors. I may have missed these bits, but blame not me but the writing. It’s also very hard to imagine a The Thing inspired monstrosities engaging in diplomacy with say human factions. — Writing. The way the lore is presented to a player are a painfully bad written walls of text that are hard to digest yet alone to enjoy. What’s worse their attempt to sound clever or edgy at times ending up reminding me of a modern Twitter speech with some annoyingly artsy notes. — Humans units design. I guess it was hard for the devs to create something of their own after all the abundance 40k has to offer. As a result most of the units from human affinity are just uninspiring and boring, lacking a consistency in design that could have suggested the technology this faction has. — Artwork — lacks consistency in quality and is too into “lovecraftian horror” gimmick. Some artwork is plain bad suggesting an AI could have done much better. — Interface — lacks any character and somehow less informative than in Gladius. I believe this design is called glass ui or something like that, and it’s totally a cancer for the modern game development. Can’t come up with something more bland and offensively boring. — Diplomacy — feels just unnecessary, especially on a medium sized map with just couple AI opponents and three NPCs. Diplomacy might have worked on a strategic level, where there are plenty of actors involved, but not on a mostly tactical layer with only a few factions available. Weird that devs didn’t think of this. — Quests… don’t even get me started. Imagine playing a strategy game planning out your moves meticulously and then a dialog pops up asking you a rather abstract question after answering which a bunch of hostile high tier units spawn near your main city… Gladly, you can turn these off. The neutral — Music — some tracks are good and add to the atmosphere, while others sound too contemporary stylistically. Either way their amount isn’t nearly enough for the soundtrack to not become annoying after just couples of hours of gameplay. Good thing is there’s no problem turning the music off, since the game has a rather decent sound ambience. What I did like. — more complicated resources mechanic, that really extends the Gladius resource management which was primarily focused on food and ore. — visuals — albeit a bit too flashy, gives a better understanding of the surface zones and tactical possibilities. I found it more immersive too, and it’s clearly a step forward from the Gladius. — Soundscape and ambience — really good sound design that adds to immersion and makes music unnecessary. More 4x strategies should invest in ambience instead of 10 music tracks that get annoying rather quickly. — Alien units design — is quite okay, especially The Thing inspired the Voice faction’s roster. — Ironman mode implementation — instead of saving the game during end turn phase, the game seems to rewrite a savegame each time you move a unit, which is a much better way to do it than the easily cheesable endturn Overall, I think it’s a step forward for the dev and I quite enjoyed some new mechanics and possibilities, but at the same time the game has become too bloated with the unneeded features that don’t add to the gameplay, and in my opinion it has a very inconsistent and underdeveloped lore. I think the game needs more content, like new human factions with better overall design and better lore too. The quests system needs a total rework and diplomacy should either go or be completely reworked. Overall, I wouldn’t recommend this game — unlike Gladius, which I sank countless hours into, I don’t feel any urge to keep playing this one. It’s just not fun in its current state.

ZEPHON has interesting hex combat with low micromanagement and high tactics, no infinite city sprawl. What's really nice about ZEPHON is it concentrates the decision space on shooting and exploration and allows flexibility in building out tech trees and customizing heroes so the different leaders can go different paths on subsequent runs. It has a metaplot that goes between rounds and personalized story quests for each leader that shake up the flow of the run. The quests branch and some are random so each run has variety. There are dedicated NPC factions separate from the player leaders that structure the run and give a timer based on story progress. The DLCs are really great because they add vertical slices of the game with more of everything - more units, more music, more leaders. Active patching helps focus the conflicts on outposts and points of interest too. It's possible to recover a run that started shaky by hanging on and using higher tech units to punch back opponents. A full run goes about 8 hours and is easy to set down if you need a break. Expanded edition is a great way to jump in.
Ive tried to find a good 4X strategy game to get into. Stellaris, Total War, CIV, Age of Empires. None had the same approachability as this. The mechanics are very new user friendly, play time doesnt require an insane amount of time, and overall,. it was fun and a great stepping stone to getting into strategy games.
This game is pretty good. My main reservation is that if you already have Warhammer:Gladius... this is *mostly* that, but with slightly less cool lore. The factions here are not Warhammer quality. This does add some diplomacy and special resources for advanced units. Also I think this game looks a *bit* nicer. Compared to the standard Civ series, this has more fighting, more tactics and unit variety. Diplomacy seems standard fare. City building is far simplified compared to Civ, that's not a criticism, it's just not the focus of the game. There's some reasonably interesting story quests.
Easily my favorite 4X game currently. Love the fact the game is essentially one large combat puzzle to be solved with some simple, but deep enough economic management to guide everything through. Every update brings the game closer to being the best it can be and I always cannot wait to see what the next expansion brings to the table. Just one more turn (to turn my enemies to dust)...
Its fun so it achieves the goal of a game but its not excellent. Maybe 7 or 6 out of 10. It contains subtle political 'messaging', overall the whole atmosphere has little bits of pieces of it. This is very tired by this point which really does give it a shadow which will taint it to me. Repeats voice lines a lot which becomes tired and can easily have you wanting to mute them... Its very aggro for a 4X which... I like it has an 'arcade' like feel to play which is honestly quite enjoyable, although the whole 'hero' units with items and stuff gets a bit to much in my opinion considering the scale of forces can be present. Some of the abilities are very meh. The research tree is a bit messy. It would be a lot better if 'non category' research was also toggable rather then the 3 'types' only, that way you can check through categories quicker. There is numerous small things like engineers have to build roads 1 by 1? Really? The fact after you move an engineer you can build a road with it to, but after moving it deselects it and selects a different unit after you move it is quite annoying. Another thing is how weird it gets with multiple cities and loyalty/population, while I understand there has to be some limitation for expansion, the current version of it of building a quarter or even half a city of entertainment districts is... a bit off.
"This isn't the world I knew." One of the most addicting X4 games I have played, with incredibly intuitive yet versatile mechanics. I look forward to excessively modding + buying some DLC for new leaders! A bit shame so many unique playstyles are locked behind a paywall, but if any game deserved my money, it's definitely Zephon
The game appears to be busted. in a few turns after starting ive gotten access violation 3221225477 and a crash. the devs haven't fixed the bug and its been maing the game unplayable for many people.
I like it - was mostly worried it might feel soulless or generic since its a new IP but no, theres some creative stuff in there and like the set up. Leaders are interesting.
