Would it be possible to make this work a bit differently (I am sure not your plan)? But where a buried nest with eggs is spawned in the starter zone, and no biters exist. Then when the buried nest is mined, biters are then enabled, or maybe upon the first escape? Or something to like that... resulting in a cataclysm where an extinct species is brought back to life through mankind's ignorant efforts, sort of a horror/monster movie kind of theme?
Story line aside, I prefer not to mess with biters until I have my base well underway. So having them not exist for a while, until I trigger them, would be a welcome game mechanic.
Biter Power and Fluidic Power, both are brilliant.
