Incubator

The Incubator is a structure in Darwinia that functions by Engineers placing Souls inside of the device. Once souls are placed into the device, over time new Darwinians will spawn from the Incubator. Not many know but, The more souls in an incubator the faster they are spawned, After the hundredth mark one can presume its more than just One darwinian spawned per second.

Theres also a variant of the incubator in levels after Receiver and Pattern buffer that don't take souls from engineers but have the souls from the Receiver and have a limit on how many they can spawn before they hit the limit of live darwinians, They emit a Red smoke from where the souls are usually kept for spawning.
