The two main gaming apps on iOS and Android that use a crossbow are Defender II and Shoot the Zombirds. These two games generally fall into the Tower Defense type of game genre.

Droidhen’s Defender II is the sequel to the successful Defender. The main objective of the game is to defend your castle from waves and waves of enemies. To attack, simply tap and aim in the direction of your targets. It will fire automatically when your finger is pressed, so you don’t need to constantly touch. Aside from that, you’ll also gain access to spells that can decimate your enemies. When enemies arrive at your castle, the life of the castle is reduced. The game ends when it reaches zero.

Each level increases in difficulty and also in the number of enemies to defend against. Some levels have bosses that will prove to be an added challenge. As with its predecessor, you will get crystals and coins after completing each level. These will allow you to upgrade your weapon. You can upgrade your various stats. The increased strength will increase your damage. Increasing agility will increase the frequency of arrows. By unlocking these stats as well, you will also gain access to more abilities and crossbow types. Upgrading the mana tower will increase your mana for spells and now it also shoots your enemies.

Also new to this version is the ability to deploy a lava pit in front of your castle. The lava pit will incinerate and set fire to all enemies that fall into it. The biggest addition to Defender II is the Battle mode. Now you can challenge other players who survives the longest. Defender II is available for free on iOS and Android with options to purchase virtual currency to upgrade your skills and weapons.

Shoot the Zombirds by IDream is the successor to Shoot the birds. The game involves you as a pumpkin head or kid shooting the undead birds in the sky and saving the little pumpkins along the way. You touch in the direction where you will shoot.

Unlike Defender II, which doesn’t run out of arrows, this game does. It forces you to focus more on accuracy and timing instead of just shooting carelessly. It won’t lose an arrow when it hits a target, but it will lose when it misses. The level ends when you reach the number of bomb kids you can afford to lose.

There are fast and slow birds. Aside from the birds carrying pumpkin children, there are flying skulls that you can hit to get gold coins. These gold coins can be used to purchase upgrades such as one-time power-ups such as rain of arrows or freezing all enemies on screen. You can also use them to increase the number of arrows and the number of bomb children you can afford to lose. Costumes are also available to purchase if you want to change the look of your character.

Overall Shoot the Zombirds is another solid game. The main draw would be its simple and polished gameplay and presentation. His theme is unique and differs from the usual ancient knights and dragons. This game is also available for free on iOS and Android with options to buy instant gold coins.
