Most of us should know what this means. If you don't, Mann vs machine, tf2, personally my favourite mode. I don't know why, but I love the theme almost as I do the rocket jump waltz (9 minute extension FTW) Spoiler: What classes I go as I only ever go as 2-4 classes. Engie. He is good in some maps, especially coal town. Harry/soldier. Again, I like soldier in coal town. I've only really played on coal town Heavy. I do sometimes go as heavy, I just can't play this class right. Too sluggish. This one is obvious. Like, super obvious. Scout. I go him when we have a lot of heavy classes, not heavy merc, heavies, soldiers, engies, etc etc.
