About
Buckle up, pilot! We're stationed above an alien planet surrounded with an abandoned mining system and filled with alien bugs. Your mission? Dive into the tamed sectors, use the mining system to collect upgrade parts and extract the Bioshards from alien minerals. Beware— the system is infested with alien bug cells spreading and waiting to hatch. Stay quick on your feet, and you might just make it out in one piece!
At the start of every expedition, the map is procedurally generated, and it's crawling with alien bugs. The cells constantly spread and evolve. When triggered, the bugs burst out from the cells to swarm you down!
Equip up to five skills each run: active ones that strike automatically or passive ones that boost your abilities. Upgrade each skill differently to maximize their potential. Discover unique synergies between skills and upgrades to optimize your build. The better your synergies, the easier you'll crush enemies!

A pointless game. Just EXTREME grind and upgrade VERY slowly. 3 levels that are basically the same. Literally no point to the game, just achievements I guess.
Game is pretty interesting and fun for a few hours. Would say its worth getting when on-sale. Not a major pain to get all the achievements either. Does feel like its lacking in content after several hours in, but its a fun way to pass a couple evenings.
Swarm Grinder offers a refreshing spin on the increasingly popular survivors-style roguelite genre by combining relentless combat with exploration, resource gathering, and environmental strategy. Instead of focusing entirely on surviving endless enemy waves, the game challenges players to venture across procedurally generated mining zones infested with dangerous alien organisms while searching for valuable Bioshards. Every expedition feels like a calculated risk, as pushing deeper into unexplored territory rewards players with resources and upgrades but also exposes them to increasingly aggressive alien swarms. This constant balance between exploration and survival gives the game a stronger sense of purpose than many of its genre counterparts, creating an experience that feels both familiar and surprisingly original. One of the game's defining mechanics is its evolving battlefield. Alien cells gradually spread throughout the map, transforming safe areas into dangerous territory until they are disturbed, triggering massive attacks from hostile creatures. This system ensures that players cannot remain stationary for long, encouraging continuous movement and thoughtful decision-making. Exploration becomes more than simply uncovering new terrain—it becomes a strategic necessity that directly influences the flow of each run. Since every map is procedurally generated, no two expeditions unfold exactly the same way, giving the game excellent replay value while maintaining a consistent feeling of tension from beginning to end. Combat is fast, satisfying, and built around experimentation. Weapons attack automatically, allowing players to focus on positioning, movement, and choosing upgrades that complement one another. Throughout each run, players assemble a build using a mixture of offensive and passive abilities that can evolve through branching upgrade paths. These upgrades are more than simple damage boosts, often altering the behavior and effectiveness of individual skills, encouraging players to discover powerful combinations and unique strategies. Every successful run feels partially earned through smart build planning rather than relying solely on quick reflexes, making progression rewarding for players who enjoy experimenting with different playstyles. Outside individual missions, Swarm Grinder provides a steady sense of long-term progression. Multiple playable characters each feature their own advancement systems, while gadgets, permanent unlocks, collectible items, and increasingly difficult evolution levels provide meaningful goals beyond simply surviving another run. The growing collection of skills, equipment, and upgrades steadily expands gameplay possibilities, giving players plenty of reasons to continue improving their characters and refining their preferred builds. Even after mastering the fundamentals, higher difficulty settings introduce fresh challenges that demand better planning and more efficient resource management. Visually, the game embraces colorful pixel art that successfully combines retro aesthetics with modern readability. Enemy designs are distinctive enough to remain recognizable even when dozens of creatures flood the screen, while vibrant attack effects create exciting moments without becoming overly cluttered. The science-fiction mining environments establish a convincing atmosphere where industrial machinery collides with rapidly spreading alien infestations. Combined with energetic music and satisfying sound effects, the presentation reinforces the game's frantic pace while maintaining a clear visual identity throughout extended play sessions. What truly separates Swarm Grinder from many similar roguelites is how effectively it integrates exploration into every aspect of gameplay. Rather than treating the environment as little more than a backdrop for combat, the game turns the world itself into an active participant through expanding alien growth, hidden resources, and meaningful navigation choices. Players are constantly making decisions about when to explore, when to fight, and when to retreat, creating a more strategic experience than traditional arena survival games. These mechanics help every run feel purposeful instead of becoming a repetitive exercise in defeating increasingly larger enemy waves. The game is not without its shortcomings. While the progression systems provide satisfying longevity, the overall amount of content may feel somewhat limited for players seeking hundreds of hours of variety. Veteran players may eventually become familiar with available maps and encounter patterns despite procedural generation. Additionally, the challenge curve can be demanding during the early stages, requiring patience before the deeper customization systems fully reveal their potential. Fortunately, the strong gameplay loop and rewarding experimentation help offset these limitations, making repeated attempts consistently enjoyable. Overall, Swarm Grinder succeeds by building upon the foundations of the survivors-like genre while introducing meaningful mechanics that emphasize exploration, strategic decision-making, and environmental interaction. Its combination of procedurally generated levels, flexible character progression, engaging combat customization, and dynamic alien ecosystem results in a roguelite that remains exciting well beyond its opening hours. Players looking for an action game that rewards adaptability and experimentation will find plenty to appreciate, while fans of the genre will likely enjoy its fresh ideas and polished execution. Rating: 7/10
the game is ok at what it does. It just doesn't have enough content to play it over other options in the genre.
It feels boring. You constantly move in circles cause the fuel/health drops disappear too quickly, and not much changes with the upgrades.
boring af
the game is fun, but it lacks content, there aren't enough options for upgrades to feel like there is much build variety to be had. there isn't any reason to pick more than one color of weapon on a run because theres a lot of upgrades that affect a specific class of weapon so picking all the same is just a better choice, but each type of weapon only has three weapons unless theres more to unlock so you will just have the same three every run of a specific type and thewy each only have like 6 upgrades to put into they 3 slots they have so you can just always get the three you want once you find the best combo you will have no reason to pick anything else. if the game had like twice as many upgrades and weapons to pick it would be great as the gameplay is really fun but as it is it just lacks content to make there be much reason to play past a few run in my opinion
Games like "Swarm Grinder" make me wish that Steam games could be graded on a scale instead of a thumbs up/thumbs down system. Yes, I like the game. I have 100-percented its achievements. Yes, I gave it a thumbs up, but this is a very hesitant recommendation. It does some incredibly unique things that I haven't seen yet in other action roguelikes, but it has one really, really big problem: namely, the stuttering. When everything slows down to a crawl and then FREEZES during some pretty mild firefights, I just throw my hands up and exit out of the game completely. I would have demanded a refund for any other game that froze as often as "Swarm Grinder." But it is a helluva fun game -- when it works. I kept coming back to it until I got all the Steam trophies. The solo indie dev who made this is clearly talented when it comes to game design, but for the love of God, please do something about the stuttering.
Eğer Vampire Survivors türündeki "bullet heaven" oyunlarını seviyorsan ama biraz daha strateji ve aktif oynanış arıyorsan, Swarm Grinder tam aradığın o bağımlılık yapıcı mekaniğe sahip. Bu oyun, seni bitmek bilmeyen düşman sürüleri yerine, haritada aktif olarak "kazarak" ortaya çıkardığın bir böcek istilasına karşı hayatta kalmaya zorluyor. Deneyim Oyunun en büyük farkı harita yapısı. Düşmanlar sadece üzerinize koşan kalabalıklar değil; siz haritadaki hücreleri deldikçe ortaya çıkan, uyuyan bir kovanın parçaları gibiler. Bu da size ne zaman ve ne kadar risk alacağınızı seçme şansı veriyor. Mekanik bir zırhın içinde, topladığınız geliştirmelerle (bio-tech) kendinizi durdurulamaz bir kıyma makinesine dönüştürmek inanılmaz tatmin edici. Her "run" sonunda kazandığınız kaynaklarla zırhınızı kalıcı olarak güçlendirmek, o klasik "bir tur daha" hissini tetikliyor. Neden Oynamalısın? Görsel tarzı tam senin sevdiğin o detaylı ve canlı pixel art estetiğine sahip. Patlamalar, ateş saçan silahlar ve ekranı kaplayan böcek sürüleri arasında geçen o kaos, harika bir görsel şölen sunuyor. Farklı karakterler ve her seferinde değişen rastgele yetenek kombinasyonları sayesinde her deneme bambaşka bir strateji gerektiriyor. Üstelik oyunun temposu oldukça yüksek; kahve molasında bile bir tur atıp stres atabilirsin. Artıları: Haritayı kazarak düşman uyandırma mekaniği türü taze hissettiriyor. Çok şık ve akıcı pixel art grafikler. Yetenek ağacı ve karakter geliştirmeleri oldukça derin. Sinerji yakaladığında ekranı temizlemek büyük bir dopamin kaynağı. Eksileri: Bazı bölümlerde zorluk seviyesi aniden çok yükselebiliyor. Türün doğası gereği bir noktadan sonra kendini tekrar ettiğini hissedebilirsin.
Last few minutes of first run on Steam Deck had single digit fps. Really needs optimization.
