You have your orders, "defend this location at all costs". The alien ships will soon be upon you!
The purpose of this game is for when you want a quick blast. If you want a space shooter where you gradually progress through different levels, you need Attack Velocity.
Please note you'll need a middle to high end phone or tablet to play optimally. The paid version includes an extra map, with more coming soon, and no adverts.
