Summum Aeterna is an ambitious and demanding roguelite action title that expands the dark fantasy universe previously established by its creators, offering a faster, more repeatable structure built around endless runs and procedural worlds. Developed and published by Aeternum Game Studios S.L., the game places players in the role of the King of Darkness, a powerful yet eternally trapped ruler whose journey is defined by failure, rebirth, and gradual mastery. Rather than following a traditional linear progression, the experience is designed around constant experimentation, where each run becomes both a test of skill and a strategic decision made long before the first enemy is struck. One of the most distinctive aspects of Summum Aeterna is its seed-based world generation system. Instead of relying purely on random layouts, the game allows players to craft worlds using seeds that contain specific modifiers, referred to as genes. These genes influence nearly every aspect of a run, including enemy density, biome structure, rewards, hazards, and difficulty scaling. This system turns preparation into a meaningful part of gameplay, as choosing a seed can drastically alter how a run unfolds. Some seeds create relatively forgiving environments ideal for farming resources or learning mechanics, while others are intentionally brutal, offering higher rewards at the cost of relentless pressure. This approach adds a layer of strategy that goes beyond reflexes, rewarding players who understand the game’s systems as deeply as its combat. Combat in Summum Aeterna is fast, punishing, and built around precision. Movement, positioning, and timing are critical, as enemies are aggressive and mistakes are rarely forgiven. The game features a selection of weapons that meaningfully change how encounters play out, ranging from traditional melee options to heavier, slower tools and even ranged firearms. Each weapon comes with its own strengths and weaknesses, encouraging players to adapt their playstyle rather than relying on a single dominant strategy. Weapon customization further deepens combat through a gem system that allows abilities, modifiers, and special effects to be slotted in, enabling builds focused on raw damage, crowd control, survivability, or risk-heavy burst potential. When everything aligns, combat can feel exhilarating and powerful, though it can also become overwhelming when multiple systems collide during especially difficult runs. Progression is a core pillar of the experience, ensuring that even failed attempts contribute to long-term growth. Defeat returns players to a central hub where resources earned during runs can be invested into permanent upgrades. These improvements enhance base statistics, unlock new weapons, expand available mechanics, and gradually smooth out the game’s initially harsh difficulty curve. However, the depth of this progression system can be a double-edged sword. With multiple currencies, upgrade paths, and interconnected mechanics, the game can feel dense and intimidating, especially early on. Players willing to engage with this complexity will find a rewarding sense of control and customization, while others may feel burdened by the sheer amount of systems competing for attention. Visually, Summum Aeterna embraces a dark, hand-drawn 2D aesthetic that leans heavily into gothic fantasy. The environments are moody and oppressive, filled with sharp silhouettes, ominous architecture, and biomes that feel hostile by design. While the procedural nature of the levels means that some areas can feel familiar after extended play, the art direction consistently supports the game’s tone, reinforcing the sense that the King of Darkness is wandering through cursed worlds shaped by decay and conflict. Enemy designs are varied and often grotesque, and boss encounters stand out as memorable highlights, combining striking visuals with demanding attack patterns that test everything the player has learned. The game’s difficulty is unapologetic and forms a central part of its identity. Summum Aeterna expects players to fail frequently, especially in the early hours, and it offers little hand-holding in return. Enemy damage is high, traps are lethal, and momentum can be lost in seconds. Over time, however, mastery begins to replace frustration, as upgraded abilities and improved player skill gradually tilt the balance. This makes success feel earned rather than granted, though it also means the game is not particularly welcoming to those unfamiliar with demanding roguelites or action-heavy platformers. Narrative elements are present but understated. Rather than delivering a story through long dialogue sequences or cutscenes, Summum Aeterna relies on atmosphere, environmental hints, and sparse interactions to communicate its themes. The focus remains firmly on gameplay, with lore acting as a backdrop rather than a driving force. Players already familiar with the broader universe may appreciate the subtle connections, while newcomers can easily engage with the game without feeling lost, even if the story itself remains intentionally distant and abstract. In the end, Summum Aeterna is a complex, challenging, and system-heavy roguelite that prioritizes depth, replayability, and player-driven experimentation over accessibility and immediate gratification. Its inventive world generation, demanding combat, and layered progression systems combine to create an experience that rewards patience and persistence. While its complexity and steep difficulty curve may deter some players, those who enjoy mastering intricate mechanics and embracing repeated failure as part of the journey will find a richly constructed game that continues to reveal new possibilities long after the first victory.

類rogue遊戲 每過關一個難度就可以開啟下一個難度 以全成就來說至少要打16個難度(0~15) 難度曲線提升有點誇張 難度0~3 接近類銀河戰士惡魔城的難度 尤其在熟悉敵人攻擊時機加上在據點設施(強化玩家能力數值)有所強化之後會更上手 難度4~7 已經逐漸傾向類魂遊戲 副本賦予敵人的詞條數量開始變得有點誇張 敵人總數2倍以上外加敵人反應速度加快50%幾乎是必備 難度8以上 感覺近乎要玩家達成0受傷過關的操作實力 原先據點的設施強化對玩家的能力造成的優勢又變得幾乎沒用 一般敵人攻擊就會讓玩家少一半的體力(敵人詞條幾乎常駐2種屬性附加攻擊) 每次進新的房間就是5個以上的敵人在1秒內對玩家進行攻擊(幾乎常駐敵人3倍數量以及反應速度加快100%) 玩法變成進新房間攻擊2~3次快速退回前一個房間 祈禱門口敵人可以慢慢地減少 頭目更是一次攻擊會有70%的傷害 完全不能期待回復道具 只能靠降低傷害幾秒鐘的道具撐過頭目戰 難度8之前都還可以接受 但是至少設計成門口不要放敵人 高難度感覺就像把無雙類遊戲做成類魂一樣恐怖
I decided to give up on completing 100% of the achievements. The max level seed I completed was 121. And the idea of getting to 150 looks just not postible for me. But I've enjoyed my time playing this game. It still could be polished in many aspects, but was a great experience.
великоплено. играйте на джостике. жаль настройки управления сменить нельзя. на клавиатуре управление боль. в первые такое не удобное управление встречаю
Game seemingly exists to fund the Lucis and looks to have done that initial job. Combat is fun for a while before it becomes overly repetitive for way too little payout to the player for the hours of investment it asks per unlock. Ultimately you run in circles for hours but instead of cheese at the end you get a thumbs up. complete 50/50 on the rec. Support the studio for their next game if you're a fan or looking for an enjoyable few hours of timesink. If you're looking for a revolutionary roguelike I doubt this will be it for you.
Where to begin. This games animation and hit boxes are not quite right I think my biggest issue is I'm a huge dead cells player and although that game is hard its not unfair. And before I get the get gud squad thinking its a skill issue i have beaten dead cells on bc5 all bosses no hit. The combat has a lot of off screen ranged enemies and you have 2 options 1 stay and fight them which consists of dodging their attacks until they are in range which takes minutes in some cases. Or run and take damage while fight other mobs. Then there's the stagger it is rng sometimes you can stun lock the enemies and other times the exact same enemy just attacks randomly. It feels like this was made by someone who was described dead cells/bloodstained and then ran it through google translate. Its a shame but at least i picked it up on sale so it didn't cost too much
I’m really enjoying this game. It controls great and looks good with nice upgrades. It’s worthy of a buy anytime if you are going to play it. This game reminds me of my favorite fast food when I’m hungry. By no means the greatest but a very enjoyable game.
I have mixed feelings towards noctis for various reasons, but the movement (would describe it as fluid) definitely seemed solid to me. So taking that as a starting point for this genre seemed interesting to me. This isn't the most complex rogue-lite, but I'm really enjoying it. There was enough build variety, enough upgrades and options to keep me hooked. There isn't much change for each biome per run, each biome has its own boss you'll get every time. Not really ideal, but for me at least this is one of those games you can both easily get into a flow state kinda thing or play while listening to a podcast or something. But I really dig what this game does with run generation via seeds. You'll eventually be able to do whatever kind of run you want (probably like 15+ hours). The game has a pretty slow ramp up, like I'd say for the first 10 hours or so. I still found that beginning part fun, but after that your options really open up.
