Yes.

Trying to survive is hard enough, surviving with zombies everywhere doesn't help. However these guides help your survival rates go up and your deaths go down.

So you've got a Mann Up ticket, and you want to put them to good use. But maybe you've never played Mann Up before. Or maybe you've never even beaten advanced before. Because of my lack of faith in you endless generosity, I've decided to compile a list of guides for MVM to help you not be dead weight!

Now, that's a lot of guides, so I wouldn't expect you to read them all in one session, but I would recommend you read "Drawing and Losing Aggro", the class guides for the classes you want to play, and skim through "METAMETAMETAMETAMETA".

Do something cool and you might get it.
