New bullet damage model
This update changes how much damage bullets from firearms deal and how armor works.
First of all there are a lot more calibers than before and each weapon should use the right one.
Damage is independent from the weapon now and only depends on the fired caliber and bullet type.
There is a new modification slot for each weapon, that lets you choose the bullet type. For most calibers, there are 4 bullet types:
Full metal jacket
Hollow-point -> ~ +20% damage, -20% armor penetration
Armor-piercing -> ~ -20% damage, +20% armor penetration
Incendiary -> ~ +15% damage, +15% armor penetration, 4% fire chance

Armor model
There are 4 armor classes now: Level 1 - Level 4 with protection values 20, 40, 60, 80.
A bullet will penetrate the armor if it has enough penetration power (> protection value).
Bullets with at least 10 more penetration power than the protection value of the ammo, will deal the full amount of damage to the unit
Bullets with penetration power that is close to the armor protection value will slowly start to deal a little more damage
Bullets will very low penetration power (< protection value - 10) will only deal 10% of their damage

This will result in small calibers from pistols will almost do no damage through level 3+ armor
However, armor has a durability value now, which will get lowered with every hit. Again, bullets with high penetration will damage the armor more that low penetration bullets.
Once the durability reaches zero, the armor will not protect the unit anymore.

The bullet and armor changes will need some more adjustments in the next updates, but I think it's a much better system because the damage on the weapons is easier to balance, less random and the armor does actually do something. Also, there will be more armor items available in the next updates, so feel free to share your suggestions about armor.

Dyeable armor
From now on, you can change the colors of Helmets, Chest armor, Arm + Leg armor like the colors of clothing items.
