# Vehicle Combat Crossover

Section 123 defines `VehicleCombatCrossover.V2`, a combat-racing catalog for
Demolition Derby, Vehicle-Hijack, Fight-On-Vehicle, Truck/Bike chase, Convoy
Raid, and their ranked queues.

## Demolition Derby

Demolition Derby is an enclosed arena mode where 4-16 vehicles fight until only
one remains. It tracks per-vehicle HP, collision damage, and driver melee
weapons: punch through window, headbutt opponent, and mounted weapons from
Section 104.2. Arena types cover classic bowl, figure-8, industrial yard,
stadium, and parking-garage multi-level. Vehicle Totaled from Section 97.8
eliminates the driver with a cinematic flaming-vehicle KO. Team mode supports
2v2, 4v4, and a shared HP pool option.

## Vehicle-Hijack

Vehicle-Hijack is a Combat Racing Section 104 crossover stipulation. With the
crossover ruleset enabled, a player alongside an opponent can trigger
driver-side window melee combat and a short input-RPS where attacker and
defender contest control. Success transfers the opponent vehicle and racing
position. Every hijack has a cinematic with input-prompt UI for attacker and
defender, and costs meter or power-up consumption.

## Fight-On-Vehicle

Fight-On-Vehicle is cinematic fighting on a moving vehicle. Two fighters trade
blows while racing through open-world streets with passing traffic, overpass,
and cop pursuit hazards. Compatibility covers convertibles, trucks, bikes
rider-vs-rider, and pod racers cockpit-vs-cockpit; every compatible vehicle has
an authored fight-stage. Section 14.2 hot-spot finishers adapt to vehicle
contexts: toss opponent into oncoming traffic, ram opponent bike into pillar,
and throw opponent from pod-racer into chasm.

## Truck/Bike Chase

Truck/Bike chase is an open-world chase where one heavy truck driver pursues 1-3
bike riders. Bike riders can attack the truck, use a climb-aboard finisher, and
lasso truck pillar points; the truck can ram bikes off road. Narrative scenarios
cover bandits, cartel, rival crew, and cop-vs-fugitive contexts.

## Convoy Raid

Convoy Raid is a 2-4 player co-op mode where an attacker crew fights an AI
convoy defender protecting valuable cargo. Attackers split between drivers who
chase down the convoy and fighters who board convoy vehicles to steal cargo.
Defenders fight back and call backup. Cargo types cover armored car, armored
truck, multi-vehicle convoy, armored helicopter, and mobile-stage celebrity NPC
passenger.

## Ranked Queues

Crossover ranked queues cover Demolition, Hijack, Fight-On-Vehicle, Truck-Chase,
and Convoy-Raid. Each queue owns a separate MMR bucket.
