Что вас ждёт: напряжённые сражения с волнами крыс в ограниченном пространстве; разнообразное оружие и улучшения под ваш стиль игры; постепенное повышение сложности и серьёзные испытания на поздних этапах; битвы с особенно опасными противниками; погоня за лучшим результатом и соревновательный дух. Каждый забег — это проверка реакции, точности и тактики. Используйте окружение, правильно подбирайте улучшения и не давайте крысам окружить вас.

Open BuzzLens and within seconds virtual insects are flying and crawling around your real room. Hunt them with a tap — no scanning ritual, no account, no waiting. THEY BEHAVE LIKE THE REAL THING Every bug runs its own little life. It notices your gaze, spooks at fast movements and loud noises, darts behind real furniture, waits you out and sneaks back. Creep up slowly — or lose it. HUNT BY EAR Every species has its own spatial buzz. Close your eyes and you can still find the mosquito. Headphones recommended. A WHOLE COLLECTION OF SPECIES, ONE LEGEND Mosquito, fly, beetle, cockroach, moth, grasshopper, a firefly that only comes out in the dark — plus the legendary Golden Mosquito: impossibly shy, lightning fast, ×10 points. Moths crave light: switch on a lamp and set a trap. FIVE WAYS TO HUNT • Hunt — the classic three-minute round • Blitz — one minute of pure adrenaline • Silent — any noise empties the room • Collector — fewer targets, rarer finds • Survival — 15 seconds, every catch resets the timer COLLECTION & FIELD NOTES Every catch goes into your collection. Keep catching a species to unlock notes on its behavior. Synced via iCloud. QUESTS & GAME CENTER Fresh quests every day, three leaderboards and a shelf of achievements. PRIVATE BY DESIGN Everything runs on your iPhone. Camera and microphone are processed on device and nothing ever leaves it. No account, no ads, no tracking. Requires an iPhone with an A12 chip or newer and iOS 17. Best played with a desk lamp on and headphones in.

Verdict
The clearest difference is ads: Keller Rats at none against BuzzLens's shown. Keller Rats also leads on update cadence (every 4 days vs every 11 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.
