Perhaps one of the most criminally misunderstood games of all time though likely intentionally, the facade may be too effective at doing its job. Ultros is a strategy game about environmental manipulation and planning. It presents itself as a standard Metroidvania adventure with a reset gimmick and can even be played entirely as such, but that isn't the game. It is horrifying to imagine that anyone would choose to engage with it exclusively on that level but judging from other Steam reviews and achievement statistics it seems few are able to put the pieces together. Early on you're introduced to the concept of growing plants via sci-fi seeds, it seems like a kinda neat auxiliary mechanic at first that probably wont get much use but this couldn't be further from the truth. Every worthwhile system in this game involves these plants, their growth, and their intersection with the game world. Frankly I don't even think the Metroidvania stuff is worth talking about, the platforming, the combat, the world design, you're ultimately going to be using your head to circumvent and avoid those things if you're properly engaged with the 'real game'. I'd go so far as to say the standard genre elements are a gag at the players expense, lotta people didn't even know they were being pranked though (or really hated finding out). It's all a big sandbox you're meant to create a network in and efficient route through while trying to maximize the effectiveness of your limited resources within a cycle. Don't go in looking for a good Metroidvania experience I'd say it's actually a downright bad one if played that way. If you want something with weird freaky boundary pushing game mechanics punching way above their weightclass this is your game (even if it may take you a few hours to get there was ~4 till I 'got it'). Also for the love of god its not a roguelike, there's basically just an elaborate resource limit that people mistake for roguelike mechanics. All that being said, Ultros is also horrifically buggy. I got visual bugs, audio bugs, all kinds of clipping, save corruption (theres a sort of system in place for backups but lost of few hours and the risk of it happening again is high) unfortunately the more you engage with the game the more general instability you will encounter. I wouldn't hold out any hope for any bug fixes either seems like the dev team disbanded based on a bit of research I did which is unfortunate to say the least, they really made something special here even though it needs a few more boatloads of polish. It should say a lot that I still wound up feeling it was a worthwhile experience despite these unacceptable blights. Approach with extreme caution, its like a cool toy that may spontaneously combust before you're done playing with it... and also said cool toy is hidden inside another toy that sucks, at least the seam is obvious to those with eyes to see.

This game was made for exactly me. The designers had one person in mind when they made it. ME. The combat is good but not too deep. There's combat, but it's not about that. This game is about "exploration". Exploration of the environments and the mechanics. Each cycle you learn more and can do more and never once was I just "stuck" trying to figure out what to do. I just kept... stumbling into a new idea or a new dimension. That is the game's crowning achievement. It unfolded in multiple dimensions at exactly the rate I needed it to. This isn't "rogue-like" in any way.. You reset the world sorta and some of the things you did linger behind.. But that's the only thing. It's not rogue-like, it's just another dimension added to the retraversal of the "metroidvania" genre. You unlock player capabilities, which reset with each loop. But you'll start "locking these in" so that you don't have to unlock them more. Most notably there's just not that many and before long you'll have them unlocked very early on each cycle. Here's the kicker, you can feed the creatures of the world to create gardens, where you can plant seeds which grow things like platforms or many other effects. THESE are what stay between "cycles". YOU GROW YOUR OWN MAP. I loved just sitting in the art and the music. Here are my responses to common arguments that I see on other Steam reviews: - "The game lost me when I lost my seeds and food at the time loop." The resources you're operating with are a part of the ever expanding range of your capabilities. This doesn't get in your way just go with the flow and expand your map in whatever way you choose during that cycle, then choose a new approach on the next. - "The game is too visually noisy." This -- as always -- goes away when you gain a tiny bit of familiarity.

This game rips. Really smooth movement, a visual style that pops off the screen, and just enough friction in mechanics that makes me want to keep poking at it. Discussing some very early gameplay mechanics that may put some people off at first glance People complaining about this “not being a metroidvania” because you repeatedly loop to the beginning and reset your unlocked skills either didn’t do any exploration, didn’t go beyond the first loop, or both. You very rapidly can find ways to lock in your skill tree and find permanent movement and exploration tools. This is a game about wonder and exploration and you are extremely rewarded for getting your hands into the colorful goop.

This is an unconventional Metroidvania about discovery through gardening. It's not a roguelite. The game starts to click around the 3rd loop. That's when you start to understand the game and what it wants from you. Seeds, compost and fruits replenish so dont worry about the time loops. If you're stuck then it's because you need to use the Splicer more and learn the plants. Good luck gardeners and remember you can feed your enemies so they leave you alone.

I once asked El Huervo to marry me. He said no. At least i tried. Oh yeah, about the game i don't really feel like this is a "metroidvania". As a fan of SotN AND Super Metroid I feel like this game is much closer to Metroid than to anything from Castlevania... and this is a good thing. The whole game feels very rounded and complete, everytime I thought about the possibility of the game softlocking me I found out I could solve that problem in like 10 different ways. It has a goal since the beginning and it stays faithful to that until the end, one thing that i really enjoyed is how it "fixed" something that was kinda weird in Metroid itself... like there Samus didn't give a ♥♥♥♥ about the creatures on the planet until the very last minute of the game (which is fine since Metroid was based on Alien after all), but here those ideas are blended in a way that feels much more organic. Talking about the new ideas, maybe this isn't exactly a good "first metroid game" (or first metroidvania) for someone. It has some unique mechanics that are interesting but they could definitely scare beginners a bit... Not because the game is so hard it demands some pro-player reflexes (actually the game is pretty chill and this is another reason why I think it feels more like Metroid) but because it can overload a beginer brain with questions about how things work and how to deal with them + are there something missable (there are no missables) + am I really progressing.... It's bold to add new things that are definitely not familiar to this genre, specially when it's something that takes so much effort, when you see ALL THE POSSIBILITIES IT OPENS UP.... seriously, once you unlock all the "skills" the gardening goes wild. And all of this is glued together with this amazing art style and soundtrack which really deserve to be experienced with a good set of headphones. (niklas let me play your next game and i forgive you for breaking my heart)
