Costs

Most stats are bought on a sliding cost scale. The base cost to do so is as per the table below.

Level 1 - D4 - 1 CP - Hobbyist/Amateur
Level 2 - D6 - 3 CP - Trained
Level 3 - D8 - 6 CP - Professional
Level 4 - D10 - 10 CP - Skilled Professional
Level 5 - D12 - 15 CP - Experienced Professional
Level 6 - D14 - 21 CP - Expert
Level 7 - D16 - 28 CP - Master
Level 8 - D18 - 36 CP - Ancient Master
Level 9 - D20 - 45 CP - Superlative
Level 10 - D22 - 55 CP - Exemplar

In short, the base cost to improve a stat costs (current level + 1). Depending on the stat being bought, this may be multiplied as follows.

Attributes have a x5 multiplier.
Specializations have a multiplier of (4 + 1 for every additional specialization in the same attribute). Furthermore, Specializations may not be higher than 1/2 (round down) of the base attribute.
Skills have a variable multiplier. If no value is listed, it has a multiplier of 2.

Attributes & Specializations

These are the defining 'hard' characteristics of your character. Attributes provide additional dice to be rolled to any associated skill, while Specializations increase success cap under appropriate circumstances.

Physique

This is the raw physical prowess of your character while she is on her own two feet, governing everything from strength, agility, endurance, athleticism and general toughness.
Available specializations for Physical are:

Dextrous

Big

Fit

Intellect

Your innate intelligence, as well as your ability to notice things and act on your feet.
Available specializations for Intellect are:

Quick-Witted

Intelligent

Perceptive

Charisma

Charisma measures the likeability of your character in several ways. Although few player characters are anything but superior in physical attractiveness, those with high Charisma do tend to be the coolest or hottest, and they do tend to sell more figurines.
Available specializations for Charisma are:

Attractive

Manipulative

Friendly

Aleph

Alephs (or colloquially, Newtypes) are, depending on whom you ask, the next stage in human evolution, an ability gained due to the invaders, their faith in God, or something that has been with us all along. Your character's Aleph rating governs her access to "magical" abilities.
Available specializations for Aleph are:

TBD (role-specific)

Skills

Skills are things your character has learned how to do. Swordsmanship, spellcasting, accounting, monster ranching, all are skills. Skills are broken into various groups, depending on what attribute or specialization they are controlled by. Skills provide both rolled dice and success cap.

Somatic

This includes things like swordsmanship, fistfighting, track and field training and null-gravity movement.

Athletics

Brawl/Martial Arts

Melee

Firearms

Legerdemain

Stealth

Endurance

Resolution Rules

Fundamentals

Dice pool size is equal to the appropriate Attribute. Dice pools are rolled using dice of the appropriate size (skill 1 being D4s, skill 4 being D10s, etc), with every dice equal or exceeding the target number scoring one success. Having a suberbly-toned mind or body doesn't make up for lacking in critical skills.

Specializations can be used to reroll any dice, even a success - possibly resulting in a Max Roll and the benefits therein (see below). It takes 2 rerolls to reroll a 1.

For most tasks the target number will be 6 to score a success, but many things may modify this up or down. Note that positive modifiers increase the target number and are thus bad whereas negative modifiers decrease the target number and are thus good.

Rule of 1s
A 1 on any dice eliminates one rolled success; a reduction to less than zero successes results in a fumble. Fumbles are generally disadvantageous in some form but should not be specifically punishing or lethal (unless it's a rather explicitely dangerous situation, like fumbling your Use Lightsaber or Tightrope Over Lava rolls). Rerolling a 1 costs 2 Specialty rerolls.

Rule of Max
By contrast, rolling the maximum value on a dice lets you do one of two things. In both cases an additional max result lets you continue rolling until no more max rolls are made.

If the roll is not a success, you may roll again and add to at -1. (eg, a 6 on a D6 rolls again at -1, giving a total of 6 to 11)

If the roll is a success, you may instead roll an additional dice. (If the difficulty on the above roll was 8 and the second roll was 6, for a total of 11, you may roll a new dice and attempt to get another success)

Rule of Supremacy
If the roll exceeds the difficulty by at least 100%, (ie rolling a 12 when the difficulty is 6), you may opt to roll another dice as if you had rolled maximum and gotten a success, as per option 2 of Rule of Max.

Damage and Survival

Hitting with a weapon requires at least one success; bare-handed attacks, melee weapons and ranged weapons with Precise add one dice to their damage roll for every additional success scored on the to-hit roll. Attempts to dodge, parry or otherwise avoid the attack eliminate successes on a 1:1 ratio.

All normal characters (ie humans or transhumans) have the following hit point tracker:

-0 hit points equal to Physique plus Big, + 1

-2 hit points equal to Fit + 2

-4 hit points equal to Physique + 1

Incapacitated hit points equal to Physique plus Big, +1

Any damage past this will land the character in the morgue or, if they're lucky, in a long-term regeneration tank or download pod.

Parahumans, cyborgs, etc may have modified trackers due to their sometimes wildly different anatomy or physical structure.

Mecha Resolution

Mecha and other war machines are unsurprisingly a core part of More Robot Wars and have their own statlines, and for the following section 'Mecha' can be taken to read as any vehicle-sized object such as tanks, airplanes, giant robots, etc. Starships and similarly-sized entities are broadly similar with a few additional rules to reflect their size.

Mecha Stats

The following stats are the core values for mecha and serve to describe the platform itself.

Agility: Agility is a measure of how responsive a mecha is to its controls. Agility adds a positive modifier to to-hit rolls made against the mecha, as pilots will naturally take advantage of a machine's agility to avoid shots. Agility also adds a negative modifier for melee attacks' to-hit rolls.

Speed: Speed is a measure of how fast a mecha moves. Speed can also be used to Zoom and Boom (see Advanced Actions below).

Strength: Strength is a measure of how strong a mecha is. It acts as a negative modifier for melee damage and additionally is the size limit for any non-fixed weapons - weak mecha can't exactly carry around 500mm hyper mega autorails.

Output: How much Power the mecha's onboard power system generates per turn. This may be 0 for vehicles or mecha with fixed-output power systems or battery-powered units.

Battery: The maximum amount of Power a mecha's onboard power system can store. The amount of Power in a battery may temporarily exceed its maximum value - the hyper mega beam cannon is being powered directly by the reactor while also drawing down the battery. Any excess at the end of the turn is removed.

Electronics: This is a measure of the generalized onboard electronic gear of a mecha, ranging from sensors to targeting equipment to ECM. See the Special Moves section for the full effects of Electronics.

Stealth: This is a measure of how difficult a vehicle is to detect with sensors. See Advanced Actions for more detail.

Armor: Armor is a measure of how difficult is it to breach the physical defenses of a mecha. Armor is the target number for Penetration rolls.

Resilience: Resilience is a measure of how resistance a mecha is to damage. Resilience subtracts from the damage inflicted by weapons strikes.

Durability: Durability is essentially how difficult it is to render a machine unable to fight. More durable mecha can fight longer. It is essentially the mecha's 'hit points'.

Carrying: This is a value for how much 'stuff' a mecha can carry externally, such as mecha-scale assault rifles, missile packs, sensor pods, etc etc. Most giant robots and aircraft have high carrying values as they use externally-fitted weapons. Carried weapons and systems provide flexibility, but the downside is that they are much easier to lose.

Weapon Stats

Weapons have their own distinct statline with several values as follows.

Accuracy: Accuracy is a measure of how easy it is to hit with a weapon, and it adds a negative modifier to to-hit rolls.

Burst: Burst is a measure of how fast a weapon can fire and adds its value to the dice pool on to-hit rolls.

Slow: This is for weapons with extremely long cooldown periods; a weapon with Slow must wait for that many rounds to fire again.

Range: This is how far the weapon can fire accurately. Going up to double this imposes a -2 Accuracy modifier, tripling -4, so on.

Penetration: Penetration is the dice pool rolled to penetrate Armor on a successful hit.

Strength: Strength is how much additional Durability damage a weapon can inflict and can also be used to reroll Penetration dice. Generally speaking, Strength correlates to explosive power/area of effect; Strength 0 is pure kinetic/energy impact and increasing levels represent some form of explosive effect.

Draw: How much Power a given system needs per turn simply to remain active. Systems can be activated or deactivated as desired, though they can only be on or off during a specific turn.

Charge: How much Power a given action takes; for example a flash shield might have a Draw of 1 for standby and then have a Charge of 1 per attack blocked.

Weapon Abilities

Hardened: The weapon is strengthened with integral forcefields and energy-dissipating alloys. It can be used to parry/block Overpower weapons without being destroyed.

Disruptor #: The weapon has enhanced ability to penetrate non-physical defenses. It reduces the Shield rating of a target by the Disruptor rating.

Armor Piercing #: The weapon has enhanced ability to penetrate physical defenses. The difficulty on Penetration rolls is reduced by the Armor Piercing rating.

First Strike: The weapon can strike from beyond normal melee range and consequently gets an extra attack upon entering melee combat.

Entangling: Can be used to disable an enemy's weapon (normally melee). Specifics TBD

Grapple: If an enemy fails the first roll (Seek Opening) in a Melee Lock situation, the Grappler may immediately make a counterattack as per normal rules.

Overpower: The weapon will automatically destroy any non-Hardened, non-Overpower item used to block it. Crunch!

Limited Ammunition #: How many shots the weapon has before it needs to reload (available seperately). This typically represents weapons that have bulky, heavy ammunition.

Precise #: The weapon is optimized for high-precision attacks, including enhanced targeting equipment, accurized barrel, etc. For every # successes above those required to strike, the weapon gains +1 Penetration.

Scatter #: The weapon has a variable-aperture muzzle, adaptive focus or some similar feature that lets it 'spread' its shot widely at the cost of terminal effectiveness. For every point of Penetration spent, the weapon gains +# Burst.

Assault #: The weapon has an extremely high rate of fire and can easily put a large number of beams or shells on a target in a short period of time. For every # successes above that required to hit, the weapon scores an additional hit, resolved as per normal rules.

Advanced Actions

The rules above cover basic combat as portrayed in most scifi, with intense close-range furballs and madly jinking attack craft. While these will suffice for games that do not have a strong vehicular combat component, for ones centered around military units or other situations where giant robot combat is common the following rules provide greater depth and diversity.

Melee Lock

Mecha fighting each other with melee weapons can be likened to humans doing the same. And like their small counterparts, a mecha trying to disengage from a melee fight risks getting hit before it can open the intervening distance. This is Melee Lock, the tendency of melee combatants to stay in melee.

Breaking Melee Lock is an action, with associated penalties if multiple actions are taken. It is an opposed roll, Mecha Fighting modified by Agility. If this roll is failed, there is no effect; an opening is not found. If it is successful, the initiator must now roll Piloting/Speed against the enemy's Mecha Fighting/Agility. If this second roll succeeds, the initiator can immediately make a normal move. If the roll is failed, the enemy can immediately make a counterattack at current penalty (if any), and then the initiator can immediately make a normal move.

If any time a melee combatant botches a melee weapon strike roll, the enemy craft can disengage from Melee Lock with no roll and move its remaining move away, if desired.

Zoom and Boom (aka Lightning Strikes)

While the normal flow of combat assumes that fightercraft will be engaged in turning contests and complex, high-agility maneuvers to gain position, in some situations high-velocity craft will instead perform rapid strikes before pulling away to come about for another pass. This is common in air combat and rather less so in vaccum.

In space, a Lightning Strike allows the performing unit to accumulate excess velocity above the norm and essentially 'slash' past the target(s), firing all weapons then (hopefully) coming about outside of the target's defensive envelope. For every turn a unit is Lightning Striking, it may increase or decrease its maximum move by 100% (one 'level'); however, its minimum move is also increases (or decreases) by one full level. EG, a mobile suit with move 5 doing a lightning strike can move between 6 and 10 spaces on its first turn. Machines doing Lightning Strikes must also move their minimum distance before making a turn of no more than one side.

A craft doing a Lightning Strike has other advantages; it replaces its Agility with its Speed for offensive

Dive Bombing (aka landing on a spaceship and shooting the crap out of it, point-blank)

Mecha that are at 0 or 1 range from a ship are assumed to be 'dive bombing', which allows them to ignore many defenses a ship has as well as precisely place their shots in weak spots.
