Armor Piercing Ram-jet Rail gun Round

    This Rail gun round was designed to have better armor piercing/ Critical Strike abilities with longer ranges. The casing has vibro-blades that surround it on all sides. The farther the round flies, the faster ramjet pushes it and the hotter the vibroblades get. Thus at different ranges, it has different armor piercing success. The Archer Mecha is designed with this as the primary weapon.

    The center chamber holds the explosives in the front 2/3s while the last 1/3 holds the charge and the ramjet fuel. The charge is for the vibroblades to function. It is specifically designed to penetrate the armor and explode sending the hot vibroblade shrapnel into the inside of the target. (See the optional Critical Damage Rules below)

    The round is stored in a casing that keeps the vibroblades down in the casing which keeps them disarmed. Once the round leaves the barrel, the blades pop out and arm the projectile. It requires it's own special rail gun in order to be launched. Not every railgun can launch this round because of the square ammunition case and the oval barrel..

    Rate of fire: 4 per melee because of heat problems caused by the vibro blades as it runs down the barrel. The round is initially launched by magnetic force and it's speed is compounded by the mini-ramjet.

    As the round flies farther the Critical Strike roll gets better. The AP-R has a limited ranged in atmosphere. Once the blades get too hot, or the fuel runs out, the round explodes. In space, the round isn't as effective, but it's range is much farther. The vibroblades still work in space because of the e-charge, but the armor piercing ability does not change with ranges. In space the critical strike roll is always 18,19,20.

A critical strike is determined by the NATURAL strike roll. It does double damage, and the GM may opt to use the Critical Strike results chart.

There are two variations available. The first in the original round. It's maximum range is 1 1/2 miles (2414 meters). The second type was created for longer distances. It's maximum range is 10 miles (16 kilometers) in regular atmosphere. It is very accurate with its course correction capability. These also need to be fired from the same special rail gun.

Type 1) Original Armor Piercing Round Stats in Regular Atmosphere

Damage per round: 3D10+15
Rate of fire: 4 shots per melee
Range: 1 1/2 miles ( 2414 meters). As the round flies further, the Natural Roll for a critical strike gets better!! At the max range, the natural strike roll just has to be equal to or above a 13 for a critical strike!
Cost per round: 2000 credits

Critical Strike Ranges are as follows:

Type 2) Long Range Armor Piercing Round Stats in Regular Atmosphere

    The long range version has flaps in the back of the vibroblades for slight course corrections since it flies so far. There is a small processor that hold the guidance information. The damage has been reduced because the ramjet fuel has been increased. The vibroblades have also been constructed and set at a lower frequency to take the greater heat as the friction increases during fight.
Damage per round: 3D4+10
Rate of fire: 4 shots per melee
Range: 10 miles ( 16 kilometers). As the round flies further, the Natural Roll for a critical strike gets better! At the max range, the Natural strike roll just has to be equal to or above a 10!
Cost per round: 3000 credits

Critical Strike Ranges are as follows:

** Critical Strike

A critical strike can occur when a NATURAL roll equals or rolls above the Critical Strike criteria (i.e. Natural 20). Also, in some cases, a critical strike can be assigned with a specific maneuver like a strike from behind. Any successful strike that receives DOUBLE DAMAGE can be classified as a Critical Strike. See below for OPTIONAL RESULTS.

Use this rule when any mecha, robot or machinery receives a critical strike, or if they are below One Third of their Damage Capacity. This chart determines if they receive Critical Damage. If the roll is above 40% on the following chart, then critical damage occurs.

When critical damage occurs anywhere including the main body, roll to see what kind of Internal Damage is caused. This means that the armor was penetrated and a vital function was damaged. Subtract the damage and roll on the following charts.

Roll % dice and 1D4 at the same time to get the results on the following charts.

Roll for the extent of damage on the following chart:

Compounded damage is accumulative. One level after Heavy means that the system type in that area is destroyed. (i.e. If the first hit to an arm is light electrical and the Second is also light electrical, the compounded damage is Medium electrical. Or a single strike that inflicts Heavy damage, includes those heavy penalties AND the penalties of the Light and Medium types as well.) The charts below will determine the penalties.

Again, all damage is accumulative. So Light damage to weapons + light damage to weapons again = Medium Damage. The penalties are added to the previous.

Roll for type of damage inflicted for each time a damage level is determined.

Types of Damage:

Internal Structure: These are the "Vital Organs" of this piece of machinery. When damaged, the hit will slow down the response time of that area. If the internal structure of that part is destroyed, then it is no longer functional. Chances are it will need to be replaced.

Joints: Joints are any moving part on the machine from elbow joints to neck joints. Damage to these parts will impair the abilities of the machine. (i.e. If the elbow of a power armor arm with a mounted gun is frozen, then the pilot will have to maneuver the whole body of the power armor to point the gun in the correct direction.)

Electrical: This is all of the wires and devices which transport electricity from the power source to the devices.

 

Weapon Systems: These are the sensors and instruments that allow control to your weapons.

 

Use the results of the previous charts to determine the penalties that occur because of the Critical Damage.

Mecha

This is the 'Long-Bow Archer' mecha that houses the guns for the Armor Piercing Round.

This mecha is small and light and designed mainly for sniper, anti-aircraft, and long range attacks. But it does have a few close range weapons since the cannon is not very effective at short range.  It is created by Megaton Enterprises. It is NOT a glitterboy class mecha.

The main feature of this mecha, besides the cannon, is the separate hover-drone unit that it uses called a "Squire". The squire has the main targeting sensors, radar, the 'radio radar' as well as a few weapons that synchronize with the mecha's weapons. It has many different types of sensors and is often used to hover above the tree lines, hills and other radar and targeting obstacles to feed the information back to the mecha. The mecha have been know to set the gun through a small hole or in between a bunch of trees while the squire sets up the target. The Squire can also attach to the mecha and therefor produces the ability to hover which adds to the speed of the mecha.

The mecha also uses a different version of radar. Instead of using Microwaves (which it is also equipped with) it mainly uses directional low or high frequency radio waves. These are not usually detected like conventional radar, so the target rarely knows that it is being targeted until it is hit.

Another "different" feature of this mecha is that is has sub woofers on each upper arm. Since the cannon is a rail-gun, it creates a sonic boom when it is fired. The sub woofers have been synchronized and setup to emit a sound that counters the sonic boom at the instant that it fires. Only the initial sonic boom is countered while the next booms can't since they are from the rounds acceleration. This quiet shot allows the mecha to fire and move before its exact whereabouts are discovered.

The rail gun that is mounted on the Archer does not initially propel the round at extreme velocities. Therefore the recoil is minimal. This causes the Archer to be able to fire and move. The rail gun creates a sonic boom because the round reaches the speed of sound when it exits the barrel. The round continues to accelerate with the help of the ramjet installed inside the round itself.
