An overcoming darkness known as Red Horizon is upon us. You are Captain Fisher, pilot of Earth's last defense fortress STS-51. Use its cannon to battle increasingly difficult enemy waves. As the game progresses, you will be able to upgrade your cannon and unlock different skins.
How long will you survive?
I haven't been able to beat wave 12. The game plays great and is pretty entertaining for anyone in the mood of a mix between classic arcade shooter, shump and bullet hell.
You can unlock different skins, but I just wish there were more. You can use the coins to upgrade the cannon though.
