What if you wanted to play a mobile game that recently came out… but the developers said no? Chaos Zero Nightmare is the latest game from Supercreative and Smilegate, the same team behind my beloved Epic Seven. I played it from around day three-ish for about two months, and I enjoyed it a lot more than I ever thought I’d enjoy a card battler. I’ve never seriously played one before, and all my card game knowledge comes from Yu-gi-oh, but now I’m more than a little bit intrigued. I’ve even bought games like Slay the Spire and Darkest Dungeon to try out one of these days.
I would have loved nothing more than to explore the worlds in Chaos Zero Nightmare some more, leveling up my characters, finding and evolving new cards, and all that other fun stuff people play card RPGs for. Unfortunately the game had three main flaws: 1. Stamina restrictions, 2. Low variety in content, and 3. Rigid builds that killed excitement.

Also a really crappy translation/localization
1. Stamina restrictions right out of 2005
Or whenever it was that developers still thought that letting people play your game for long periods of time was a bad idea. I mean I kind of get that it’s a new game and they don’t want people rushing through and complaining of no content… but then the solution is to launch with more content! Or give players regular stamina infusions so they can check back in throughout the day. Barely a week into the game, I had already started checking in only once a day to do a few dailies, run out of stamina after three or four battles and turn it off again. You know what comes after checking in once a day? Checking in (chaos) zero (nightmare) times, that’s right.
It seems that game developers don’t quite understand the situation they’re in right now. When you release a game in October 2025, you’re not just competing against other games released in 2025: you’re also competing against every other gacha game still running, some of which have had over a decade to add content and find ways to keep their player base busy. So when you say, “Hey, don’t play with those old toys, try these ones instead,” you’d better be sure there’s something substantial in the toy box.

2. Low variety in content
After a few weeks of not much going on, Chaos Zero Nightmare released its first content patch. This featured a side story with special dungeons offering cards that couldn’t be found anywhere else as well as weekly challenges and achievements. On the plus side, this didn’t require any stamina so we were finally free of restrictions. On the minus side, it turned out to be just running the same dungeon over and over and over again to get good builds to challenge the seasonal content, since you couldn’t use your regular deck builds.
I believe they later relented on that, but don’t quote me because I quit. Instead of injecting new life into CZN, the first patch rather exposed how repetitive the game was, since it was 90% running dungeons, with every dungeon taking at least 15 minutes to complete, usually more. IIRC the developers have promised to add ways to speed up each run, including allowing players to skip cutscenes, but I’ll believe it when I see it.

3. Rigid builds killing excitement
The point of running dungeons (90% of CZN‘s content, as I said) is to build decks. In other words you’re grinding to make your characters stronger, as is typical in gacha games. There are other ways to make them stronger like Memory Fragments (weapons) and Potential (stat boosts), but most of your time is spent trying to get them good skills and artifacts in dungeons. Every character starts with a number of basic cards. They gain and develop more cards and skills through “epiphanies” they have while exploring. For example if they have a card that heals, it can gain an epiphany and become a card that heals and gives 2 AP every time it is used.

Here you see that Hugo’s skill can develop in one of three ways.
So far, so good. Multiple evolution paths for a skill is pretty interesting. Unfortunately, the majority of characters in Chaos Zero Nightmare have one, maybe two optimal skill sets. If you don’t get the right epiphanies on that run, you just wasted 15 minutes of your life. Delete save data and try again. I won’t lie and say they’re completely useless without the optimal sets, but they’re pretty close to it, and some like Mei Lin genuinely are worthless without sparking the right epiphanies.
Unfortunately, even if you do spark the right ones, sometimes the game won’t save them at the end of a run… Right, I forgot to mention that the game will not-so-randomly refuse to save some of your skills if they cost too much. Another 15 minutes of your life gone. Then you have to start from zero in the same dungeon using the same skills against the same enemies again because CZN is a roguelite. *facepalm*
Note: All these issues should improve with time
Needless to say, I’ve dropped Chaos Zero Nightmare for now. But it’s only dropped “for now,” not forever. That’s because the game hasn’t been out for even six months yet, and the devs are already showing signs of improving things. For example, right around the time I quit, Supercreative and Smilegate were making save data accounting more transparent so you could know whether all your skills were going to be saved or whether you were over the save limit. They also explained how epiphanies, monster cards, etc. were weighed in the calculations to help increase understanding. TBH this is obviously stuff they should have launched with so I’m not too impressed, but I can tell the game will be very different in two or three years if they keep going at this rate.

Arrrghhh…
In a couple of years, the game roster should grow as well, along with the types of equipment they can use. This should, in theory, create more diversity in teams so I won’t be running Tressa/Hugo or Tressa/Cassius forever. Plus I want to believe that the developers will find ways to shorten dungeon runs, and prepare a greater variety of things to do with the characters. The story hasn’t gone anywhere in the six chapters I played either, so there’s a lot of room to develop that. Not expecting much on that front, though: it’s going to be all Chaos Chaos Chaos forever. After all, if they ever manage to solve the Chaos problem for good, the game will be over.
Aaaanyway, in short, I’m setting Chaos Zero Nightmare aside for now, but I’ll be keeping tabs on the game’s progress so I can hop back in when things finally get interesting. The game shows a lot of progress and I liked using my favorite characters like Mei Lin, Tressa, and Hugo. I’ll play other things for now (almost done with Harvestella, it sucks now) and check back in around the first anniversary.
