I can't risk an assault on the Tyranids at this stage. Besides not knowing where they are, my minions have only ballistic weaponry, which the 'nids have long since adapted to. Hell, they're used to stuff like bolters and lasguns. Using conventional guns would only result in wasted ammo for me and dead minions to feed the swarm.

Until I can steal the secrets of some future tech or even tiberium, I don't really have any means of directly combating them.
