Inatmo Vehicle Combat

Attacking from a vehicle moving 25 h/u is equivalent to attacking through a gale-force wind. Attacking from a vehicle moving 45 h/u is equivalent to attacking through 100 mph wind.

The drag, vibrations and high-velocity forces make it nearly impossible to win an attack roll from vehicle Bee. The armour rating of the vehicle increases depending on the speed differential.

It is nearly impossible for attackers from the higher speed vehicle to attack the slower speed vehicle, but the reciprocal is not correct.

The base armour rating of 500 applies to an unarmoured civilian vehicle that has no combat hardening. If the vehicle has an armour rating through combat hardening, that value becomes the base instead of 500. A vehicle with an armour rating of 700 moving 30 h/u would have an armour rating of 1000.

Driving skill is not combat driving skill. Driving skills and handling class will keep the vehicle from crashing during combat. A driver may attempt evasive maneuvers by making a Driving Roll.

Combat driving skills will increase the vehicle’s moving AR by 50 per combat driving skill level. Combat driving skill two increases the vehicle’s base armour rating from 500 to 600.

We do not bother with flanking in vehicle combat. There is no advantage to flanking when vehicles are entirely randomly created. A vehicle’s flank could be as forbidding as its bow.

Players often want to "shoot out the tires" of a vehicle. To even consider targeting specific components, the persona must have combat driving skills. The persona must also be familiar with the vehicle. She could be attacking her vehicle, or the vehicle is part of a fleet of well-known vehicles.

The remaining bonus proficient depends on the player’s kilodie attack roll. If the player’s attack roll is 850 and the vehicle’s armour rating is 800, her remaining bonus proficient is 50. This value allows her to move the hit location on the vehicle up and down by 50 points. The remaining bonus proficient value cannot exceed the persona’s bonus proficient for the weapon.

Players often want to "shoot the driver" of a vehicle. This attack is a variation on targeting a component described above. The player can move the damage location to the crew cabin with whatever remaining bonus proficient she has. Moving the damage location to the crew cabin allows her to make an attack roll on a selected passenger.

The player can then make an attack roll on the target persona. The player can only use the remaining remaining bonus proficient on her attack roll. To "shoot the driver" requires two successful attack rolls. If the player does not win her second attack roll, the attack misses, and the vehicle is not damaged.

Referees may wish to adjust the amount of damage even further. This rule is optional. For every 75 HPS in damage, the attacker makes an additional extent of damage roll. Thus a single attack that inflicts 230 HPs in damage to the vehicle would make three extent of damage rolls at +75 and one roll at +5. A fusion grenade attack could damage every component on a vehicle and not just destroy a single component.

The extent of damage roll indicates the decrease in efficiency of the damaged part. Major damage would decrease function by 40% from its previous efficiency. The player calculates a 40% drop in efficiency by multiplying the existing efficiency by 0.6. Major damage to a 30 h/u speed component reduces the maximum speed to 18 h/u. Vehicle system damage is cumulative.

A vehicle component is disabled when reduced to 10% of its full performance. From a practical standpoint, the mechanism may become useless long before it reaches 10% effectiveness. The damaging effects of successful attacks are cumulative, and repeated attacks will destroy a component.

Any component destroyed by a single attack is damaged beyond repair. If cumulative damage destroys a component, the repair is still possible.

Nope. Trying to use self-powered thrusting and striking weapons against a vehicle will result in a pedestrian collision for the attacker.

Type B attacks are self-powered projectile attacks. When making an attack roll against a moving vehicle, the player may use a Type B attack. Using Type B attacks from moving vehicles is usually not possible. The attack roll penalty for speed effectively eliminates all Type B attacks from vehicles. Arrows, axes, and shuriken cannot compete with the winds of high-speed vehicles.

Powered projectile attacks use their mechanical, magical and energy forces to overcome vehicle combat. These attack types are still subject to enormous penalties due to differentials, vibrations and wind drag. Individual weapons may reduce the penalties applied due to the wind effect. For example, a lazer or energy weapon is much less affected by air turbulence than a bullet.

AOE weapons are grenades and aerosols. Area of effect attacks must score a direct hit on the vehicle to damage the vehicle. Typically Type AOE weapons only need to target a specific hex. The AOE Attack Roll must beat the vehicle’s speed-adjusted armour rating.

Due to the unique chemical nature of Aerosols, a successful attack roll will hit the vehicle.

These are bespoke combat accessories baked into the inatmo vehicle. Vehicle weapons are generated during inatmo vehicle fabrication. Built-in vehicular weapons use compensating gimbals, servos, and possibly software to improve high-speed combat. These components significantly reduce the penalties suffered due to wind drag and speed differential.

Ramming involves an intentional collision between two vehicles. Or the intentional collision between a vehicle and a persona. Mutual ramming happens automatically, and the vehicles and passengers are damaged.

Jumping onto a moving vehicle is fraught with risk. Without special effects and camera speed adjustments, boarding is nearly impossible. Nevertheless, players will want to have their personas board moving vehicles.
