Development Bounty - 100 to 125 USD

[ReadThisNamePlz]

Hello! I've decided to open up a bounty. 
I, along with a few others, have been wanting to see some sort of 'infestation' event and possibly game-mode. Essentially, Xenomorphs. 
I do not want them to be actual xenomorphs, however. I am thinking more along the lines of reworked Gremorians that can be played by players. 

What I am looking for - 

• Must be player controllable and have unique abilities. Similar to what Xenomorphs had.
   
• Must have the ability to create more, without relying on the cost of crew/player life. No chest bursters. 
  • I am not against the idea of there being a way for "nutrients" to be used to further their progression, but I do not want the event to rely on the death of others to continue, like Zombies. 
     
• Five Types (Six if you count the Larva).
  • Ranged, Melee/Basic type, Builder/Healer, Juggernaut/Tank, Queen.
  • Each type needs to have a set of basic abilities, but one or two that are unique to themselves. 
    • The Basic type should have - Ability to travel through vents, pry open doors, destroy walls, spew some sort of acid, and of course a scratch and bite attack. Also, they should have the ability to devour heads, like the Vaurca Warforms for health - so it isn't always reliant on a nurse archetype.. Or perhaps there can be some sort of nest item/floor type that'll passively heal. 
    • Ranged - All basic abilities, but with a ranged attack. Similar to the Horror form Bone Dart, just.. more powerful. 
    • Builder/Healer - All basic abilities, similar to an Artificer. This one should be capable of building nests/areas of Operation laying eggs for more larva to spawn, ability to heal other creatures, etc. Light on attack and health, should really just be support. 
    • Juggernaut - All basic abilities, but much higher health and natural armor with strong melee attacks. Similar to cult Juggernaut. 
    • Queen - The Queen is the big bad boss. The matriarch. Think queen from CM. Strong, fast, and extremely tough. Terrible to fight alone or with two or three others, but no match against several people.
       
• Hivenet of some sort. Changeling talk is a good example, with the Queen speech being a larger font.
• Weakness to Fire
• Better Sprites that do not scream "simple-mob"
   

Here is the PR that removed Xenomorphs originally. I don't know how useful it'd be since I am not looking for a one-to-one port, but it might help?
