Unit Cost (Advanced)
From Alpha Centauri Wiki
The basic cost formula, to which there are several modifiers, is:
Cost = Weapon × (Armor + Speed) × 10 ÷ (2 ^ (Reactor + 1))
- Weapon value never less than half armor value
- Cost is halved for units with speed of one
- Cost is halved for sea units, and armor is discounted 50%
- Cost quartered for combat air units
- Armor cost doubled for air units
- Cost +25% for each unit of special ability cost
- Cost +25% if unit has two abilities and the ability it has which appears in alphax.txt first is not free (if the free ability comes second, it will increase price)
- Cost +10 minerals if both weapon and armor greater than one
- Cost +10 minerals if land unit’s weapon, armor, speed all greater than one
- Minimum cost (Reactor × 2 - Reactor ÷ 2) × 10 unless all values are one
