About The Pull Request

Port of PMC-Unga-Marines/Unga-Marines#308.
The balance has been de-russified with some upgrades being implemented differently (e.g. regeneration/crush).

There are new building blessings that Xenomorphs can purchased via Psy Strategic Points.
Each building can be purchased up to 3 times:

• Shell Chamber (250)
• Spur Chamber (200)
• Veil Chamber (300)

Sprites of the buildings appear in the order listed above:

The Blessings button is now visible to all, however it is disabled if you are not allowed to use it.
Xenomorphs can access a new menu via a button in Hive Status as seen here (outdated):

The hive now has a resource called "biomass" which can be gained by draining or cocooning.
Draining gives 15 biomass while cocooning gives up to 30 biomass overtime (including completion).
Biomass can be used to purchase upgrades. The cost of purchasing upgrades depends on their caste's tier:

• T1: 15
• T2: 20
• T3: 25
• T4: 30

Upgrades can only be purchased if their respective building is built.
Only 1 upgrade per category can be purchased. Purchasing an upgrade from the same category will replace it with no refund.

Each upgrade scales with the amount of buildings there are. List of all upgrades and category they are in:
Shell

• Carapace: Increases all hard armor by 1/2/3.
• Regeneration: Every time you heal your wounds by being on weeds, regenerate 0.8%/1.6%/2.4% max health and 0.167/0.333/0.5 sunder. This is not affected by regeneration power.
• Vampirism: When you slash a living human, heal 10%/20%/30% of damage dealt.

Spur

• Celerity: Move -0.05/-0.1/-0.15 faster.
• Adrenaline: Every time you regenerate plasma by being on weeds, gain 5%/10%/15% more plasma regeneration and 1%/2%/3% of your adjusted maximum plasma. It is doubled if rested.
• Crush: Deal a second instance of damage that is 33.3%/66.6%/100% of your melee damage with 15/30/45 AP to objects.

Veil

• Focus: Increases your melee damage by 1/2/3.
• Pheromones: Allows you to emit pheromones that increases in range and power for each building that exists. For castes that do not have pheromones, it is emitted at 1.25/1.5/1.75 power. For those with pheromones, their current pheromones is increased by 0.25/0.5/0.75.
• Trail: Leaves a trail underneath you randomly every time you move. The odds increase by 10%/20%/30%. Options are acid and thin sticky resin; it can be changed by clicking the status effect icon. Acid trail lasts a random time between 2-5s.

Biomass carries over through evolution, however upgrades do not. Caste swap/evolve at your own risk.
Note: This is only for Nuclear War as Xenomorphs in Crash do not get psydrain or cocoon.

Changes (First Testmerge - 12/8/24):

• Cocoon gives no biomass initially (down from 15), gives 0.1 biomass every 5 seconds to all, and 4 biomass to all on completion (up from nothing).
• Minions & Hivemind cannot get biomass.
• Toxin injects one tick/cycle's worth instead of 1u.
• Sticky thin resin from Trail lasts 3 seconds instead of forever.
• Biomass can be seen in the Status Tab instead of having to go through the upgrade menu to see it.
• Shell cost 300 -> 250, Spur cost 250 -> 200, Veil cost 200 -> 300
• Pheromones scaling 1.00 -> 0.75.
• Trying to stack pheromones will boost it instead of making an useless aura.
• Trail scales from 33/66/100 instead of 50/75/100.

Changes (12/8/24 - Now):

• Biomass is no longer an individual resource per xeno. It is now group resource for the hive.
• Drain gives 15 biomass to the hive.
• Cocoon gives 0.3 biomass per 5 seconds and 12 biomass on completion which totals up to 30 biomass.
• Toxin Mutation has been replaced with Focus Mutation which is a simple +1/2/3 melee damage increase.
• Pheromones scaling 0.75 -> 0.25.
• Trail Mutation has been replaced with Camouflage Mutation. It grants various stealthy effects: slient step (1), immunity to tactical sensor detection/pings (2), and stealth that is lost on taking damage & regained when healing (3).
• Vampirism heals 10%/20%/30% based on damage dealt making it better against no/low-armor enemies.
• Carapace no longer gives soft armor. It now gives hard armor of 1/2/3.

Closes #16737

Why It's Good For The Game

Adds scalability that isn't "evo tower primo / resin silo we need more xenos" to xenos that is similar-ish to marine's req which rewards not dying (because dying means you can't have this cool thing).
