Nova 9 was released in 1991 as the sequel of Stella 7. It is also developed by Dynamix.
The story is continue from Stella 7. After defeated by us, Draxon's ship has fallen on a planet. And there, he discover some old artifact that bring him back to power. We can see this story in the very nice introduction scene.
Soon, after receiving some weird calls from our allies, we immediately go to the planet and start our action. Of course, we still use the same tank from Stella 7, but now comes with some improvements.
In Nova 9, the detail of the polygons are improved a lot. And the enemies are now more distinctive with the increased polygon count. Even though the terrain is still flat, but there are more decorative objects in Nova 9.
The weapon system in Nova 9 is improved as well. There are two types of bonuses that we can collect, one are those will take effect immediately once we pick them up, the other one are those can stay in our weapon storage and we can use them when we need it.
The best combination of weapon should be black bullet + three shoots + auto aiming. With this configuration, all enemies will be destroyed in seconds. The bosses in Nova 9 are tough to be defeated. Their abilities and designs are also unique. It also means we have to find our the weakness of each one before we can defeat them.
To be frank, I like Nova 9 a lot. I did spend a long time playing and trying to complete the 9 levels. It is indeed very difficult to complete the game, and it depends on what bonus that we are given during the levels.
You should give it a try even on today's standard. You can download Nova 9 here.
