In Defender for Android you must have fast fingers and a sound defensive strategy to protect your medieval castle from monster attackers. Luckily, you have a pretty sweet bow (with unlimited arrows) and a pocket full of magical spells to help you in your efforts.
As monsters charge your castle walls, tap and hold your finger on them to shoot your bow. For larger waves of targets, you can also drag your finger across the screen to get that machine-gun-spray effect. And when you find yourself being overrun by a particularly feisty pack of monsters, just drag one of your powerful spells onto the screen and watch the magic happen. But be careful, because you have a limited amount of Mana (energy to perform magical spells), and it can deplete rather quickly.
To start the game, you are equipped with only a tiny reservoir of Mana and a basic bow. As you progress, however, you begin to collect coins and jewels, which can be used to make purchases from a long menu of upgrades. You can strengthen your castle walls, purchase a larger Mana reservoir, learn new spells, up your strength and shooting speed, and of course, unlock new bows.
With its fun tap-and-drag style of game play and its incredibly addictive upgrade trees, we think Defender for Android is a winner. In future iterations of the game, we'd love to see more spells and enemy types, but even as it is now, we highly recommend this free download.
