Apollo 23 is a space shooter that at first glance looks like an Asteroids clone
But it is much more than that.
You can upgrade your space ship to make it shoot more bullets, turn faster, accelerate faster but also break better.
Furthermore, instead of the classic meteors, you get to deal with boss meteors, alien spacecrafts that shoot at you and many more.
The fun is endless. It is perfect for a quick game as you may save at any time, and continue later at exactly where you left off.
