Okay, so not sure how accepted this may or may not be by the community but I'm going to throw it out there.
A lot of people are saying that this spider monster might be some sort of parasite or of parasitic origin. I agree with this and what if one of it's abilities were to create some sort of minion?
This monster is basically being speculated to be a parasite or necromancy type of monster and what if they're right? I mean look at it:
It's almost as if a human was taken over by this parasite and turned into this monster so what if you could spread your parasite and as some have since speculated to "raise the dead"?
What if one of the monster's abilities is to use something that is already a part of the game...
The Dead Colonists
Now it might seem a bit far fetched but when you think of the original idea of a parasitic monster it was
So what if they had something similar? There are dead colonists spread throughout the maps on maps like Fusion Plant, Dam, Refueling Tower, and a couple others I can't think of, so why not give this monster an extra purpose? Instead of only being able to eat these corpses like all other monsters can, what if you could infect them with your parasite and they would follow you like the Goliath minion you can get as a map effect and over time the parasite grows and becomes relatively powerful.
Ways to prevent OP
There is only a specific number of dead colonists per map.
After killing the "minion" it cannot be resurrected again.
The minions grow in strength over time so it discourages early fights otherwise they will be defeated easily.
It takes some time for the minion to take control over the body.
And the ability can have other uses however this is one of my ideas that I have, think is great, brainstorm it, then immediately forget everything I just brainstormed the moment that I try and write it down.
So I want to know everyone else's thoughts on this.
