In response to your responses:
Chickenzilla; One hell of a compliment man, you jump on to post first with me. Thank you.
I admit, i hasn't thought about grab immune for serk when I made Avarice. I suppose the grab immune would apply, but damage would be by a hit bases. Serk runs by, Avy reaches out and try's to grab hit, does light damage, and that's it. Lets keep the long range the same, since that makes it a dangerous foe to be dealt with (like a husk and clot mixed a bit), it's only like 15-20 feet. And yes, It could spawn on round 1, instead of a bloat.
As for Vengeance, the idea was to make a 'scary' foe, like a fleshpound. But you can't do the same thing. What makes a Fp scary? Tough, high damage, and fast when you piss it off. Vengeance is like a mini one shot Fp, fast and dangerous. The diffrence is hp. He only has med-high, so siren plus a little bit. That makes it not hard to kill him, but if your foolish and damage him without thought to kill him, he'll make you pay! It also means SS one shots will negate his VENGEANCE spikes, since he wasn't mad at the time. So, actully chicken, he is pretty weak, but dangerous if shot without thinking.
As far as you Great Brain ideas, yea, I like the idea of him making them more coordinated. How the game would do that, well... As far as reverse zed-time, yes, it is horrifying. That's the idea. Suddenly, every once and a while, the zed can whoop all your *** for a short time, and this makes the attackless brain a huge threat! (even if its a indirect one). One of the ideas I had for all my guys was shaking up the way the game is played a bit. Stand in one place, weld door, shoot guy who come from other direction. Yawn. Maybe some classes could have protection, but then It wouldn't be scary for them
Well, chicken, the idea was, YOU HUNT HER MWHA HA HA, not the other way around. You can kill the pods, and they go back tot lv one. It takes on normal, 2 minutes before one can start popping Fp. Remember, when fighting Matty, never stand still. Always hunt her and her spawning pod ilk (it makes very distinctive sounds). If she takes forever to get to you, she's doing her job. And she will almost never kill you. Those billion crawlers and whatnot will, because you refused to fight her right (like how just running from Patty gets you killed)
Now for Wannas: I like the Brain avoiding players, just behind a group, yep.
So a single, but more believable illusion, hmm? Could work (even in addition too actually).
Next part is basically what is so far, except the taking damage part, if they are more believable, that could work.
Make sure It finishes attack, since sirens attack over time.
I like this, but for mine I had it so commandos WOULD NOT see the illusion at all, however, for these more believable ones, it'll work.
And yea, I know no one likes the Fp spawns from matty, but she's gotta finish off a dumb team somehow. If you know what your doing, you'll never have to fight Fp at all.
