TGMC:Xenomorph Mechanics
Here you can check out xenomorph mechanics more in-depth, with formulas and rules taken directly from the source code.
Health and Armor
Regen is pretty complicated. It always works on weeds (or off weeds if you have CASTE_INNATE_HEALING), and changes according to several things:
- Doesn't work if you're on fire.
- Base regen is 1+3.75% max HP.
- On resting weeds (white), regen increased 20% (after all modifiers, so it's always 1.2 times faster). But you only gain the bonus if you rest.
- When standing, a major debuff (modifier is 1.1 resting vs 0.2 standing, so about 5 times as slow).
- When you have Queen of Shrike alive (on same z-level) any regen is doubled.
- Pheromones increase regen by % of max HP, depending on aura level.
Formula:
REGEN = (1 + (maxHealth * (0.0375 + 0.01*Regen_aura_level))) * Multipliers
Multipliers = (0.2*Standing + 1.1*Resting) * (1+Ruler_alive) * (1+Resting*Resting_weeds*0.2)
Regen works with a delay.
- If under regen aura, delay is small.
- Without aura, it gradually double every tick until reaches max as given by formula above. So it is worth resting for a while, but also note that timer starts working if you're standing up. So you can stand alert, wait for regen to ramp up, and then rest.
Sunder
regens a little different.
- Activation of regen is under same rules.
- Base is 0.5% per tick.
- Resting doubles regen.
- Resting weeds double again.
- +10% per regen aura level.
Sunder_regen = 0.5 * (1+resting) * (1+resting_weeds) * (1+0.1*Regen_aura_level)
Among other things, healing abilities (Psychic cure) also give 5% of HP restored to sunder heal.
Critical
After getting smacked well enough, xeno goes to critical condition. He cannot perform actions, but still affected by regen mechanics. Also, off weeds he loses 5 health per tick.
Plasma
- Resting doubles regen
- Resting weeds give +20%.
Fire damage
Fire turns off regen, auras and some abilities. Damage per tick is
(#fire_stacks + 3) * (1-fire_resist)
Pheromones
| Pheromones | Effect |
|---|---|
 Recovery |
Described above. Gives 1% regen per level. Also increases effect of healing abilities. |
 Warding |
Gives 2.5 Soft Armor (in each category) per level. |
 Frenzy |
+0.06 base speed per level. |
Aura_range = round(6+Aura_level*2)
Aura (pheromone) level (strength) is on each xeno's page. Varies from 2 to 6.
Queen mechanics
Hive leaders have Queen's pheromones (type and level). And of course they can choose their own if they posses this ability.
Rally minions summons minions nearby, note that activation sets behaviour to "aggressive". This patch Queen should get a rally point ability similar to that of Hive mind. Every minion will go there - including those who spawned after. Minions have low degree of independence, so if enemy is nearby they will aggro and attack.
Buildings
Resin wall. They regen on their own. Starts at 150 HP, regens at 3 HP per 5 secs, up to 300 HP. This maximum is same for all castes, starting health differs. Has 40% bullet resistance.
Resin Door. Has 100 HP for Drone with 1.5 Hardness and 160 HP for Hivelord with Hardness 2.
Before Containment SHitters are open, all weed costs only half as much.
LARVA SPAWN FORMULA
Points are given each minute, as below:
PTS = ((1.75 + SILOS) * (marines * 0.035 * (marines_on_ship * 3 + marines_on_planet * 2)) / (1+1.75)) * (1+Hijacked*2) + BUFF
So, taking BUFF as 0, with 1 silo you have multiplier of 2.75.
With 2 silos, you have multiplier of 3.75, which translates to 36% increase in larvas.
Buff base is 0. Updates once every 5 minutes.
Changes according to:
- Monitoring decides that balance is off.
- There is a stalemate.
- If live players are less than ghosts. Then there is
BUFF = GHOSTS * 0.75
For distress, you must gain 8 points per larva. Also, at the start you gain 2 burrowed larva.
