Swarmquell
The swarm is coming. Hold the line.
A sci-fi tower defence game for iPad. Build your defences, upgrade an arsenal of eight towers, and stop the alien tide before it breaks through.

Built for the last line of defence
Every wave tests a different part of your defences. Here's what you'll be working with.
Eight towers, many upgrades
Each tower comes in multiple versions. Mix and match your arsenal to counter every kind of alien attacker.
Made for iPad
Fully 3D battlefields designed around touch, so placing and upgrading towers feels quick and precise.
Waves that push back
Every wave hits harder than the last. Plan ahead, adapt fast, and keep the gate standing.

Your campaign progress, scores and settings are saved only on your iPad, and deleting the game deletes them. We never receive them. Your iPad's own backups may include them, under Apple's terms.Game Center

Apple runs Game Center under its own privacy policy, and we don't receive your Apple Account details. You can sign out of Game Center in your iPad's Settings at any time.Purchases
The Full Game Unlock is bought through the App Store. Apple handles the payment, so we never see your payment details or Apple Account. The game asks the App Store whether you own the unlock and remembers the answer on your iPad, so it works offline. Apple sends us sales reports that don't identify you.Crash reports
