seeking Tank game

-Console: This was a PC only game from late 80's - very early 90's. I played it on my old 486 Packard bell.

-Players: I don't recall there being any multiplayer. So single player

- style: FPS (first person shooter) simulation Tank.

- Early polygon tank shooter that took place in the future on other planets. The tanks were hovercraft and some enemies were robots and the boss's were 40 foot tall Giant Martians.

- It's not Battle Zone, But similar. This had more than green colors. The ground and horizon were visible with multicolors.

- The beginning of the game showed some alien overlords plotting destruction in a cinematic.
