This game has a lot of potential but still feels like early access. The controls in the open are pretty good but once you get into a small cave, it's ♥♥♥♥♥♥. I also felt like the tracking for some enemy projectiles was a bit wonky.
Slightly clunky controls that take a little getting used to but i had an absolute blast once I picked them up!
Stardiver is an ambitious indie sci-fi adventure developed and published by Green Planet Games that attempts to fuse underwater exploration, six-degrees-of-freedom movement, narrative mystery, and action into a single, expansive experience. Set on the alien ocean world of E_41H in the year 3076, the game casts players as a lone pilot awakened from cryosleep and tasked with uncovering the fate of a missing AI research vessel, a collapsed underwater base, and the remnants of a long-forgotten civilization. From its premise alone, Stardiver positions itself as a blend of deep-sea exploration and space-age science fiction, striving to deliver a sense of isolation, discovery, and slow-burning intrigue beneath the surface of an endless ocean. Movement is one of Stardiver’s defining features and also one of its most demanding aspects. The game uses a full six-degrees-of-freedom control system, allowing players to move freely in all directions while piloting their submersible craft. This system gives exploration a strong sense of physicality and realism, making underwater traversal feel closer to piloting a spacecraft than swimming in a traditional aquatic game. Mastering this movement is essential, as it affects everything from navigating narrow cave systems to surviving combat encounters. While this freedom is exhilarating and central to the game’s identity, it can also feel unwieldy, especially in confined spaces where precise control is required. Players unfamiliar with 6DOF mechanics may initially struggle, but those who adapt will find a satisfying sense of mastery in smoothly maneuvering through the depths. Exploration forms the backbone of the experience. The ocean of E_41H is vast and layered, featuring colorful coral fields, dark trenches, ancient ruins, and industrial remnants that hint at both human and alien histories. The game encourages scanning the environment, gathering resources, and uncovering lore fragments scattered throughout the world. These elements slowly piece together the narrative and reward players who take the time to wander off the critical path. The sense of scale is one of Stardiver’s strengths, as descending into deeper zones creates a palpable feeling of danger and isolation, reinforced by diminishing light and increasingly hostile surroundings. Combat in Stardiver blends ship-to-ship engagements with encounters against aggressive sea creatures. Battles rely heavily on movement, positioning, and weapon management rather than twitch reflexes, emphasizing the importance of spatial awareness in three-dimensional space. While combat can feel tense and visually impressive in open areas, it sometimes struggles in tighter environments where camera angles and controls become less forgiving. Enemy variety exists, but encounters can begin to feel repetitive over time, and some players may find the combat lacks the depth needed to fully support the game’s long runtime. Still, combat serves its purpose in breaking up exploration and reinforcing the hostile nature of the world. Progression is tied to resource collection and ship upgrades. Materials gathered from the ocean are used to enhance weapons, improve defenses, and unlock new tools necessary for accessing deeper or more dangerous areas. This loop of explore, gather, upgrade, and push further into the unknown gives the game a steady sense of forward momentum. However, the systems surrounding crafting and base management feel relatively light compared to the game’s broader ambitions. While functional, they lack the complexity that might make long-term optimization deeply engaging, and upgrades can sometimes feel incremental rather than transformative. Narratively, Stardiver relies heavily on dialogue and mission structure to convey its story. Much of the exposition is delivered through Zera, the ship’s AI, whose commentary guides players through objectives while also offering insight into the world’s themes. The story touches on artificial intelligence, environmental collapse, and the consequences of unchecked technological ambition, weaving these ideas into its underwater setting. While the narrative framework is intriguing, its delivery can feel uneven, with pacing issues and occasional ambiguity that may leave players unsure of their broader purpose. Lore collectibles help flesh out the world, but the emotional weight of the story may not resonate equally with all players. Visually, Stardiver succeeds most in atmosphere rather than technical polish. The underwater environments can be striking, especially when light filters through water or illuminates alien structures looming in the distance. The sense of being alone in an alien ocean is effectively conveyed, supported by a moody soundtrack that reinforces feelings of isolation and mystery. At the same time, technical roughness is noticeable, with occasional performance issues, inconsistent visual fidelity, and interface elements that feel underdeveloped. These shortcomings can disrupt immersion, particularly during longer play sessions. Overall, Stardiver is a game defined by ambition and contrast. Its concept, setting, and movement system are bold and memorable, offering something genuinely different from more conventional exploration or survival titles. At the same time, its execution struggles to consistently match that ambition, with uneven combat, limited systemic depth, and technical rough edges holding it back from reaching its full potential. For players drawn to underwater science fiction, exploratory gameplay, and unconventional movement mechanics, Stardiver offers a unique and atmospheric journey worth experiencing with tempered expectations. It may not fully deliver on every promise it makes, but it stands as a sincere and imaginative attempt to carve out a distinctive space in the indie sci-fi adventure genre. Rating: 5/10
La idea no es mala, la ejecución es pésima. Puntos a corregir: La música muy repetitiva. Los sonidos muy bug. La forma de enviar objetos al almacén muy incómoda. A veces no te enteras ni de que hay que hacer por lo mal que está la interfaz. El giro de la nave cuando das con el joystick dos veces a la izquierda o a la derecha, se ejecuta a veces sin realizarlo, y si haces eso, te metes dentro de las paredes y pierdes escudo a lo bestia. Las naves enemigas al estilo cuando se buguea no man´s sky, dejan de recibir daño y ves como estás impactando en ellas... Cuando descubres que tienes misiles ves que puedes destruir rocas al estilo Dragon Ball, pero luego te das cuenta que es solo en esa zona y te llevas una grandísima desilusión. Las paredes si te pegas a ellas buceando, ves a través de ellas y hacen que sea muy dificultoso ver por dónde tienes que ir, ya que solo ves bugs. El enemigo lanza rocas que se ve en el trailer muy bug. Tira bastante a walking simulator en el mar. Si corrigen eso y le dan más vida al mapa y cosas que hacer, puede ser un gran juego. De momento lo recomiendo por el precio 11,11€ o 12,49€ sin oferta. Esperemos que corrijan todo eso y se convierta en el gran juego que muestra el trailer. La idea de estar con una nave por el fondo del mar mola.
За свою цену вполне интересный продукт, хоть и не каждому зайдёт. Из недостатков - иногда случаются "вылеты" игры; - не привычное, а потому неудобное управление кораблём. Всё остальное относительно нормально, однако, кого-то затянет, а кому-то будет не интересно. В любом случае благодарю разработчиков за необычный проект.
Если разработчики удивляются почему у их замечательной игры смешанные отзывы, то рекомендую следующее: - почините производительность. Падение с 80 до 10 ФПС на 4060Ti это несерьезно. - разберитесь с управлением. Ваш подводный звездолёт швыряет при ускорении как овно по Енисею. - переработайте бои, посмотрите на No Man's Sky. Сделайте как там. Единственное, что удалось хорошо это введение в сюжет от ИИ корабля. Все. Больше ничего не запомнилось. Я конечно понимаю, что от игры по цене шаурмы сложно требовать многого, но хоть какое-то качество должно присутствовать.
Подводная духота с плохой оптимизацией, управление тоже не очень приятное. Для соскучившихся по подводному миру обитателей суши может на первый взгляд показаться чем-то интересным, но к сожалению даже изначально игра умудряется душить своей монотонностью. https://youtu.be/pMEUovkfg-k [code][url=store.steampowered.com/curator/32105375]Кураторская группа [h1] [b]НЕ/format[/b][/h1] [/url][/code]
ive only played a short bit but most of the time the controls are not responsive. ive only been able to save once but had to quit game several times. auto save barley works and missions dont update like mission 4 it says return to base. i went to base 5 diffrent times and it still says return.
A game with a lot of potential. If the devs could change the boost mechanic, such as refilling more fully and refilling faster, and perhaps adding more moments of combat into the game, it would make it a much more fun and fulfilling experience! https://youtu.be/uOX5ww4mjDA
Maalesef can sıkan bir oyun, kontroller aşırı saçma ve zor . Ayrıca PC'yi o kadar çok ısındırıyor ki, 15-20 dk sonra kapanacak seviyeye geliyor. Kapalı yere girince çok kötü şekilde çöküyor. Maalesef 10/5
