The universal Tiny Invaders iOS game ($0.99) has recently received an update. Now, fans of the puzzle game – which was featured by Apple in the iPhone 4S keynote – can enjoy additional content. Furthermore, a free-to-play version of Tiny Invaders has recently appeared in the App Store: users can play through 15 levels of the popular game before being asked to purchase additional content.

As outlined in the app’s release notes, features of Tiny Invaders include:

  • Innovative puzzles that require nimble fingers!
  • Intuitive one-touch controls
  • Simple to pickup and fun to master
  • 75 levels – can you get 3 stars in them all?
  • Artwork from a BAFTA award-winning team
  • Game Center support
  • Compete with your friends on leaderboards
  • Fun achievements

It’s great to see this popular game expanding Angry Birds-style, adding more content for those who’ve already paid $0.99 for the application. However, the free version of Tiny Invaders means potential customers can try the game before they buy it – this is handy, especially since iOS application rentals still haven’t launched (and potentially never will).

You can grab the full version of Tiny Birds, which is a universal application, in the App Store for $0.99. For the first 15 levels (and the option of purchasing more), check out Tiny Invaders Free.
