Hi! Can you make that main weapon a laser type? (another cannon with special ammo maybe - like AAI laser tank)
Its Annihilator with 4 lascannons after all :D
And/or make option for using vanilla cannon shells in all your tanks? There are planty mods, that have additional shells all in the same category.
I play with rampant races, and need some options to destroy them midgame.
