This mod aims to give the player a strong but fair way to attack biter nests. Factorio is all about crafting, that's why reusable laser turrets for turret creep needs another strong and more fun alternative. Vehicle turrets use ammunition rapidly, so they require ammo automation. Driving a tank, shooting explosive cannon shells while your turrets shred any biters that try to come close, also happens to be a lot more satisfying experience.
The mod adds a vehicle gun turret and a vehicle rocket turret, which follow a vehicle and use ammunition from the vehicles inventory. The rocket turret uses a new type of ammunition - rocket magazines, which are balanced around a faster attack speed. The gun turret can use custom ammo from other mods, if you manually insert it once, for the mod to recognize it. (https://puu.sh/ym2Ty/6864451b6c.gif)
Start out small with just 1 vehicle turret, and research upgrades to have up to 4 turrets per vehicle. The turrets themselves can be upgraded too, with increased health, damage and range.
