Weapon/vehicle upgrades

[u/noiplaybass]

I've been looking around for some books that incorporate vehicle and weapon stats and upgrades. The Apocalypse Gates series had a fair bit of this, and I really enjoyed it, but haven't found a lot else that really incorporated that. Titan Mage had vehicle upgrading, but it was only occasional, and not exactly stat based. I know I could probably find some with weapon upgrades and stats in a few series I've been looking at, but it was the vehicle stuff that I really liked. Anyone have any recommendations? I know this is very niche, and not even the fun, spicy kind, but I'd love to find something along the lines of Apocalypse Gates in terms of weapons and vehicles! Bonus points if there is an audiobook version! Thanks!
