【實用街機app】AstroBelt|最夯免費app-綠色工廠好玩App

While searching the galaxy for new resources, you found yourself in a dangerous asteroid field (asteroid belt).

In this part of the galaxy though, you found a great new resource that can be used by humanity. These weird, blue crystals are plenty but aren't always easy to reach.

Luckily your ship is equipped with weapons that can use this resource to shoot down asteroids. The more crystals you get, the more powerful your weapons get.

How many crystals can you collect at a time?
