Shroud

The shroud is a unit with stealth capabilities. They are fairly weak, and rely on hiding using attacks of opportunity rather than openly attacking enemies. Because they need allied colonizing enzyme to hide, they also make great defensive units. While exposed to an allied colonizing enzyme, it becomes invisible to other bacteria and predators.
