Are there any help pages for this, or maybe we can use this thread for some?

No matter what I do I can't snag a perfect score on the 2nd mission, and that's just THE SECOND MISSION!!! :P




HA! I found something!
And fuck I forgot I can't post a links anymore. :P Thanks Wakkalo.

Not all of the missions require a perfect for the bonus. That's going to be hard to do anyway when some of the humans have weapons.

EDIT: ~~STRATEGY SPOILER~~ I just got a perfect on the second mission. You have to use the mutation (syringe) tool only on people with weapons. They are very eager to kill your zombies, but they often still will panic for a moment. For one of the rooms with multiple weapon holders, I timed the entrance of a zombie horde with an injection to come at the people from both sides at the same time.
