RC: resource cost
BT: build time (unitless, maybe call it something special like Hirshelm)
H: health (how much damage it can take before being destroyed)
DM: damage
ROF: Rate of fire

Buildings don't have armor in the strict sense, so I take it when you say this you mean, "how much damage can it take?".  I know it sound sound weird to talk about building "health" so that sounds good to me.

Regeneration upgrade
- Regens every 2 seconds
- Heals 1 point at level 1, 2 points at level 2 and 3 points at level 3

Redemption upgrade
- Only will fire when alien is at 40% health or less
- Will never redeem you to a hive that's 500 range away or closer
- I can't really give you any numbers here, they are unitless. 

Adrenaline:
- Aliens within range of primal scream get energy back 60% faster.  Screams don't "stack" (umbras don't stack either)
- Aliens recover 8% of their energy per second.  Each level of adrenaline increases this by 33% (so level 3 adrenaline would give adren back double speed, at 16% of the full amount per second)

Celerity:
- Each level increases speed by set amount.
- This set amount varies from alien to alien.
- These amounts are as follows:
l1: 25
l2: 25
l3: 25
l4: 25
l5: 45

So a skulk with 2 levels of celerity moves at his base speed plus 2x25.  The base speeds for the aliens are as follows:
l1: 290
l2: 170
l3: 200
l4: 210
l5: Depends on galloping.  The max is 350. (don't worry about documenting this yet, it's a bit weird and will likely be reworked or removed)

So a skulk with 2 levels of celerity moves at 290 + 2x25 = 340

Silence:
Sounds that are affected by silence are reduced in volume.

Enhanced sight.  Oops, this isn't "Advanced Hive Sight" but enhanced "regular" sight.  Each level of this ability makes enemy structures and entities glow brighter.
It's currently a bit buggy though, as low levels of enhanced sight can make entities harder to see instead of easier.

Scent of fear - If an enemy player or structure is at 33% of their full health or below, and is within range, they show up as a special type of entity on hive sight.
level 1 - range 700
level 2 - range 1400
level 3 - range 2100
