The idea is simple: start at wave 1 and survive for as long as possible! But watch out, some asteroids aren't as nice as they first seem.
There is now a donate version of AstroBlast, for if you're feeling generous. It's identical to this version of the game (without the ad): https://play.google.com/store/apps/details?id=badger.ati.astroblast.donate
There is no limit to the maximum wave you can reach, so enjoy destroying asteroids that have different abilities, across 6 modes of difficulty (are you mad enough to try Hardcore mode?).
Competitive? Excellent! See if you can reach the top of the leaderboard against your friends. You can even share you score to social networking sites such as Facebook and Twitter. There is also now a Global Leaderboard system so you can compete against people from around the world!
Want to make the game harder? You can disable the thrust in the options menu so you can no longer dodge!
And now, you can decide how the waves play out! Select 'Free Play' mode from the main menu and you can select options such as:
* Asteroids in play.
* Rarity of the special asteroids.
* Starting and Maximum amount of asteroids as you progress through the stages.
Note: currently the Facebook app has a bug on it which will not pre-fill your status with the required text. We are working on a work around until Facebook fix this issue.
(Feeling completely crazy? Why not create stages of nothing but Cyan Asteroids with a rarity of 100%, and a start and max limit of 20 on Hardcore difficulty. Basically, it's a Danmaku game now!)
