i already saw this coming since the release of mann vs machine,
i remember discussing the game mechanics with a friend, and said "what if valve decided to replace the Robots with Zombies for the next Halloween?" and we all were like "Naaah",
and coincidentally(OR IS IT?), that actually happened..
Zombies, Couldn't be anymore generic.
But since its valve, will still play and love the game and spend all my money on keys and unlocking boxes until the announcement of hl3(hopefully)
Edit: in mvm "wave 666" mode, the robots are replaced with zombified player models wearing random halloween hats, coming in a single wave of 666 enemies, thats it
