Predators
Try sneaking up on and attacking a lone enemy with a cloaked Spear Master and see what happens.

Aliens
Bring several drones along with any hunting parties. You can use them
to drop hive nodes as you move along, enabling you to regenerate any
units that become wounded by enemy resistance. Moreover, hive nodes
see just like other aliens, enabling you to track any enemies that
cross your prior path. Finally, if you upgrade your drones, their
cystic acid spittle ensures that any hosts you subdue will produce
offspring of stronger stock than normal.
