I've been playing TF2 over the years but only recently entered its Mann vs Machine mode.
Still learning, but I think I've gotten somewhat decent at it.

I've gotten lucky a few times too:

Tour 28 - Australium Black Box
Tour 29 - Australium Scattergun
Tour 50 - Australium Blutsauger
Tour 79 - Australium Wrench
Tour 116 - Australium Black Box
Tour 194 - Professional Killstreak Medi Gun Fabricator

Am I ever gonna stop playing it? Once I get a Golden Frying Pan... perhaps.
