Here's some semi-functional excerpts:
SA.1.1 New Stats
Along with other changes to the BrikWars rules, units are given two additional stats to make them more detailed. For the sake of simplicity, they are modeled after the WH40K stats used in Necromunda. These new stats are Wounds and Leadership.
SA.1.1.2 Wounds and Taking Damage
Though most soldiers go down when their AVs are penetrated, some fighters are tough enough to keep fighting. This is represented by a secondary defense statistic called Wounds. Though most units in the game still only have one wound point, which means they behave like a normal unit, particularly tough units may have two or more points in their Wound stat. A fighter loses one wound point when he would normally be killed (i.e. his armor roll has been penetrated). When he has no wounds left, he must roll a d6 to see what happens to him.
1 Flesh Wound
The fighter is hit hard but bravely keeps fighting. He loses 1 point of skill for the rest of the current battle. The next time he takes a wounding hit, roll again.
2-5 The unit goes down. He is on the ground, barely conscious and dying. To represent this, lay the minifig prone. Units who are down lose 2 points from their skill, move, and armour values until they are taken out of action or until the end of the battle. They are only allowed to either move or make an action each turn; not both. If he is wounded again, he goes out of action (see below)
6 The unit goes out of action. It is removed from the game table and may die or sustain serious injuries (SA.4.1)
SA.1.1.3 Leadership and Testing Morale
In addition to the wounds stat, units in SoA have another one called Leadership. Leadership represents the unit's composure in battle and its ability to stay in control even when it is being blown to hell. The standard starting value for leadership is the same as its skill (base 1d6). Whenever it takes a wounding hit, or when a friendly unit within 5" goes down or out of action, it must take a leadership test. To take a leadership test, roll the unit's leadership. If the roll is equal to or greater than 1d6 + every wound the unit has lost, the unit is able to grit his teeth and fight for another round. If not, the unit breaks. If a unit is broken, it spends every turn running as far as it can away from the enemy. Whenever it has a chance to act, it uses its action to move its full movement value towards the edge of the field and forfeits its attack to dash in the same direction. Immediately after it does this it is allowed to make another leadership test. Once a unit regains its morale, it may act normally on the following turn.
And some basic units to put the stats in context:
Cost to recruit: 20 Credits
Initiates are little more than violent guys picked up off the street who think they can make a name for themselves by fighting for something. Initiates may be armed with weapons on the Close Combat, Pistols, and Grenades list. Recruits all have the following base stats:
Cost to recruit: 50 Credits
Fighters are the core of any warband, and they are based on the Brikwars Trooper stats. They may be armed with weapons on the Close Combat, Pistols, Basic, and Grenades lists.
Cost to recruit: 120 Credits
A gang can only have one leader at a time, and all members of the gang look up to him. If a gang leader is knocked unconscious or killed, then every member of his gang must immediately make a morale check, and continue to do so at the beginning of every turn until he is revived. Leaders may be armed with weapons from the Close Combat, Pistols, Basic, Special, and Grenades lists.
Armor: 1d10 (Generally Simplified to 6)
Cost to recruit: 60
Heavies are expert fighters that specialize in bringing the really big guns. Besides possessing the strength needed to hoist and carry heavy weaponry without slowing down too much, they possess magnificent skill in order to both use and maintain those weapons. Due to their immense strength, they also do a lot of damage in close combat. Heavies may be armed with weapons from the Close Combat, Pistols, Basic, Special, Heavy, and Grenades lists.
Ballistic Skill: +1
2 Power (See notes on power in BW2001) Among other things, damage done by close combat weapons is multiplied by 2.
Mechanical Expertise: if a close combat, pistol or basic weapon is broken during a battle, a Heavy may use an action to repair it. These fixes aren't permanent, however, and the weapons UR is increased by one. In future battles it may be used normally.
As you may have picked up, the weapons lists will be split into different categories that restrict certain unit types to using different kinds of weapons, making class differences more distinct, particular in the case of 'heavies' (the only ones allowed to have heavy weapons like oversized flamethrowers. Leaders should get their own BFGs, though). Experience I haven't totally worked out, but units with enough experience should be able to 'class up' at some point, giving them access to more badass equipment and character options. Splicing, for example (a Batman Beyond tech that lets you take on animal traits, from leopard spots to scales to full blown werewolf bodies) will give units interesting character options sort of like mutations in many other games (Warhammer in particular). Normal point costs are totally thrown out in favor of a new credit system that lets players collect income from territories and other resources they control and slowly build up their gang. Unevenly matched gangs won't be a problem, as underdogs can either hire mercenaries to even things out or take an 'underdog bonus' to the exp they get.
