I find the ticks too hard to hit. Even using the shotgun with wide-spread ammo having them dead center in the aim doesn’t always work. So usually I just out-manoeuvre them. That’s easy. But I think that it is very considerate by the ticks that they don’t explode in your face.
But they do that.
Am i missing something, my games they just hug the house walls, or jump against constantly the front door. Rare occasion when you stand near window or peak out they jump in.
What i meant they should always find path to closest window and directly jump in to hunt player down. Even you hiding in 2nd floor bathroom door closed. 
Yeah, that’s what I mean.
Wouldn’t that just be annoying though?
Extremely with current rate of tick spawns robots spam. Little less tick spamming and this ability would balance out nicely, i think. Just give a player incentive to fight or escape. Not just hold and wait perfect shot places.
If you stay too long in the house doing nothing, you get nibbled to death by ticks (horrible and cruel way to go).
Or fight the robots and make them D E D (dead).
