[Emperor Pan I]

Since I already know everything already, I'll add something so irrelevant to the game but I found interesting. Some people were complaining about the infester's appearance, but apparently it started as a siege units that sent out (some sort of bio bomb thing) from a fair distance, only it could be intercepted by the enemy. It later was taken out because it functioned badly against some units like Zealots when trying to intercept it, but they liked the concept art so much when the idea for the infester came up the traits were given to that unit.

That is why the infester looks a little heavy and more like an artillery bug form starship troopers, and not as fast as a unit that can tunnel under ground.
Just so you know.
