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!

Mükemmel bir oyun roguelike türünü seviyorsanız alabilirsiniz ben denemek için aldım türü sevmeyenleri bayabilir ama güzel bir oyun. Geliştirici ekibi de bayağı kalabalık. Tebrik ederim.
Last few minutes of first run on Steam Deck had single digit fps. Really needs optimization.
gut diese yallah
Прекрасная штука, когда надо разгрузить голову. Интересные комбо активных и пассивных скиллов и действительно неплохой саундтрек. Следующий, после 5 уровня сложности, называется Ад. Я уверена, что это потому, что на стимдеке он УЖАСНО ЛАГАЕТ ☹️
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.
Keyifli oyun bu türün oyunlarını çok bilmesem bile bu oyun türüne olan ilgimin kapılarını açtı
Very good Vampire Survivors clone. More fun to play moment to moment due to dash and special attacks, but the metagame is nowhere near as strong. Nice anime and pixel graphics, good music, poor enemy variety and weapon variety.
Love the game, but I found a very frustrating bug. Many times, I would say almost 90% of cases, when I cancel an upgrade, and try another one, it will keep the exact selection. I have to waste a reroll to get the actual items that fit the different update path. This is very frustrating because it ruins a run by making me waste rerolls and worst case take items I dont need, therefore waste upgrade slots.
cool concept and good execution, upgrades are that you would expect from normal roguelike, plus i appreciate that dev supports the game and doing meaningful updates
Game looked cool. Thought i would have fun and,,,, i did, Incredible game. This game is good unlike his next one, Skills are fun and every new dificulty adds more skills and enemies. Satisfying perma upgrades. There are even achievements that aren't ridiculously hard to get. Some are tied to progression. Kill enemies using certain skills to rank up (and get an achievement) Music isn't that bad. It's decent. Game definitely has at least a few hours of gameplay content. My opinion may or may not change after i play on harder difficulties and start screaming.
