Arknights is a tower defense mobile game. It's developed by Yostar Limited. You can get it for free on both Android and iOS from the Google Play Store and the App Store. It's a mobile-only game. You can download and play it without paying anything. The game has in-app purchases. You can buy a monthly pass or special packs. These give you extra resources and premium currency. There are no forced video ads. The gacha system is for getting new operators. It's one of the more generous ones in the genre.

You play as a doctor leading a team of operators. You place them on a map to stop enemy waves. Each operator has a unique class and skills. The strategy is deep. You need to think about placement and timing. The best part is the challenge. Some stages are really tough. You have to try different strategies to win. My favorite part is building my team. I love collecting operators and finding the best combinations. The story events are also great. They add new maps and characters regularly.

Compared to other mobile games, Arknights stands out. It's not just another simple tower defense game. Games like 'Plants vs. Zombies' are more casual. Arknights has more depth and a darker story. Compared to gacha games like 'Genshin Impact', it's less demanding on your time. You can auto-play stages you've already cleared. I recommend it if you like strategy. It's perfect for players who want a thinking game on their phone. It respects your time and doesn't feel like a chore.
