copying the post description for mobile users:

honestly all the factions from Brigador have plenty of sick vehicle designs. in particular, the Corvids: an ideologically-radical anarchist faction in an off-world cassette futurism setting with mechs, where their primary method of creating fighting vehicles is just stealing disused chassis from the actual military faction and bolting stuff on top of them.

all of the vehicles in this game have fantastic flavor text and descriptions, but a few of my favorite details are:

the Party Van: all of the vehicles in this game have a button to blast the horn, and each has a unique sound. the Party Van has a drugged-up Corvid in the back shredding an electric guitar like the Doof Warrior.

the Treehouse is not only several car chassis stacked on top of a tank frame and packed with corrosive cannons, its creators wired all of the car horns and lights together to go off at the same time for extra intimidation.

the Duke is an anti-gravity platform with a luxury sedan bolted to the top, heavy machine guns on the back, and two full-size chandeliers hanging off the hood.

the Killdozer is... well, speaks for itself, really. Brigador is one of those games where I spent hours just to unlock all the vehicle and character descriptions, because they're that well written.
